Support FAQ

GLA orders typically ship the same or next business day. Processing times may be extended during holidays, peak periods, or unusually high order volume. Orders do not ship on weekends or carrier holidays.

Once your order ships, tracking information is sent to the email address provided at checkout. Check your spam or junk folder if you do not receive your shipping notification.

Shipping processing time and carrier transit time are separate. Estimated delivery dates do not begin when an order is placed.

Shipping rates are calculated at checkout based on the order contents, destination, and available carrier services. Use the cart's Estimate Shipping feature to preview shipping options before checkout.

Free-shipping promotions apply only to eligible products and destinations. Oversized, heavy, or otherwise excluded merchandise may incur shipping charges even when the order exceeds the promotional minimum.

Review our Shipping Policy for additional information.

Yes. GLA provides pre-sales assistance with product compatibility, CO2 regulator selection, complete system configurations, fertilizers, and other planted aquarium equipment.

For CO2 equipment recommendations, include your aquarium size, filtration equipment, lighting, cylinder connection requirements, and the equipment you intend to operate. These details help us recommend the appropriate configuration.

Orders totaling $250 or more, and other orders selected by GLA, may require signature confirmation at delivery.

Signature requirements help protect higher-value merchandise and reduce delivery disputes.

Customers may request signature confirmation for their orders before shipment. At your request, a $7 signature service fee will be invoiced and must be paid before the order ships.

Carrier-required signatures must be completed according to the carrier's delivery procedures.

Contact GLA immediately if an address correction is required. Address changes must be requested before shipment whenever possible.

After shipment, address changes are subject to carrier restrictions and may incur a $25 intercept or correction fee. Additional carrier charges caused by incorrect or incomplete customer-provided addresses are the customer's responsibility.

GLA is not responsible for delivery delays or losses caused by incorrect or incomplete shipping addresses submitted at checkout.

UPS My Choice allows recipients to manage certain delivery preferences directly through UPS, including package redirects, release authorizations, and delivery instruction changes.

Customers who modify delivery instructions, waive a signature, or authorize release through UPS My Choice assume responsibility for the risks associated with those changes.

GLA does not reimburse packages lost or stolen after UPS completes delivery according to customer-authorized instructions.

GLA does not guarantee carrier delivery dates. UPS 2nd Day Air, UPS Next Day Air, and other expedited shipping services are subject to carrier transit schedules, cutoff times, weekends, holidays, and service conditions.

Transit time begins when the carrier accepts the shipment, not when the customer places the order.

GLA does not reimburse expedited shipping charges solely because the carrier delivers later than its estimated delivery date.

Carrier service guarantees and eligible refund claims are governed by the carrier and their applicable terms.

Shipping carriers may experience delays caused by weather, routing problems, operational interruptions, customs processing, or other transit conditions.

If a package appears lost or significantly delayed, contact GLA with your order number and tracking information. Carrier investigations or claims may be required to determine the appropriate resolution.

Once a carrier confirms proper delivery, customers are responsible for securing their packages. This includes deliveries made to apartment offices, mailrooms, package lockers, and authorized delivery locations.

If tracking indicates delivery to an incorrect address, notify both GLA and the shipping carrier for investigation.

Report shipment damage within 24 hours of delivery.

Email GLA with your order number and clear photographs showing:

• The damaged product.
• The exterior shipping box and shipping label.
• Internal packaging and protective materials.
• Any visible damage to the shipment.

Retain all original packaging and damaged merchandise until GLA provides instructions. Carriers may require photographs, packaging, and other documentation during an investigation.

Failure to retain required evidence may prevent completion of a carrier damage claim.

Report incorrect or incomplete orders within 24 hours of delivery.

Include your order number, a description of the missing or incorrect merchandise, and photographs when requested.

No. GLA refillable CO2 cylinders ship empty and must be filled locally before use.

CO2 refill services may be available through welding gas suppliers, beverage gas suppliers, fire equipment service companies, and other qualified compressed-gas providers.

Contact the supplier before visiting to confirm cylinder size, valve compatibility, and filling requirements.

Contact GLA immediately if you have placed multiple orders and want them combined.

Combining orders requires GLA approval and is only possible before the affected shipments have been processed or dispatched. Combined shipping is not guaranteed.

GLA will determine whether combining the orders is practical based on fulfillment status, product requirements, and carrier arrangements.

Contact GLA immediately before the order ships. Corrections or cancellations must be requested before shipment.

Once an order ships or tracking information has been issued, cancellation is no longer available. Shipped merchandise is subject to the applicable return eligibility requirements.

CO2 regulators, systems, pressurized components, and other non-returnable merchandise are not eligible for voluntary returns due to incorrect customer selection.

Contact GLA before ordering if you are uncertain about product compatibility.

Yes. Green Leaf Aquariums ships from the United States to eligible international destinations.

Certain products are restricted based on import regulations, carrier requirements, or destination-country limitations.

International customers must verify local import requirements before ordering. If shipping rates are unavailable at checkout, contact GLA for a custom shipping quote.

GLA dry and liquid fertilizers ship within the United States only.

This restriction is maintained because international fertilizer shipments involve varying customs, import, and regulatory requirements.

International orders containing fertilizers will be adjusted or canceled at GLA's discretion.

GLA may remove the fertilizer items and refund their purchase price while shipping the remaining eligible merchandise, or cancel and refund the entire order before shipment.

No. Import duties, VAT, tariffs, brokerage charges, customs fees, and other import-related expenses are not included in GLA's product prices or shipping rates.

The recipient is responsible for paying applicable import charges required by the destination country.

GLA does not collect or pay destination-country import charges on the customer's behalf.

International customers must accept delivery and pay applicable import charges required for clearance.

If a shipment is refused, unclaimed, or abandoned because the customer fails to pay customs duties, taxes, or other charges, the order is not eligible for a full refund.

Outbound shipping, return shipping, carrier charges, customs expenses, and other costs incurred will be deducted from any available refund.

No refund will be issued for merchandise not returned to GLA in recoverable condition.

International orders may be modified or canceled when merchandise cannot be shipped because of carrier restrictions, import requirements, destination-country regulations, or product eligibility.

Restricted items may be removed and refunded when the remaining merchandise can be shipped. GLA may cancel and refund the entire order when shipment cannot be completed.

GLA determines the appropriate adjustment before dispatch.

Yes. Customs authorities control inspections, import reviews, holds, and clearance procedures.

GLA cannot guarantee customs clearance times or the release of shipments restricted by destination-country import requirements.

Customers must confirm product admissibility and any required import documentation before ordering.

GLA is not currently registered to collect or remit UK VAT.

Orders shipped to the United Kingdom with a combined merchandise value of £135 or less will be canceled and fully refunded before shipment.

Orders exceeding £135 are subject to applicable import VAT, customs duties, and carrier handling fees payable by the recipient.

The £135 threshold applies to the combined merchandise value of the shipment, not to individual items. Separately stated shipping and insurance charges are excluded when calculating that merchandise value.

For complete details, review our International Shipping Policy.

Returns and exchanges require prior approval and must be requested within 7 days of delivery.

Approved returns receive a Return Authorization (RA) number valid for 30 days from issuance. Merchandise must be unused, uninstalled, undamaged, complete with original packaging and accessories, and suitable for resale as new.

GLA inspects all returned merchandise before issuing any applicable refund. Products that do not meet the return conditions may be rejected or receive a reduced refund.

Certain products are not eligible for returns. Review the complete Return Policy before requesting authorization.

No. GLA CO2 regulators, CO2 systems, reactors, and pressurized equipment components are not eligible for returns, exchanges, or change-of-mind refunds.

This restriction includes incorrect product selection and compatibility mistakes made when ordering.

Qualifying manufacturing defects are handled separately through the applicable warranty process.

Customers should contact GLA for compatibility assistance before purchasing CO2 equipment.

The following products are not eligible for voluntary returns:

• CO2 regulators, systems, reactors, and pressurized components.
• Dry and liquid fertilizers.
• Used, installed, or altered merchandise.
• Special-order and custom products.
• Clearance and sale items.

Original outbound shipping charges are nonrefundable on approved returns.

Orders shipped under a free-shipping promotion will have the actual outbound shipping cost deducted from the return refund.

Customers also pay return shipping and insurance. A 10%–25% restocking fee may apply depending on the inspected condition of the returned merchandise.

GLA CO2 regulators include a Limited Lifetime Warranty against qualifying manufacturing defects in covered mechanical components, including the original regulator body, pressure-reduction mechanism, factory-supplied gauges, precision needle valves, covered mechanical manifold components, and original factory-supplied bubble counter assemblies.

Mechanical coverage continues for as long as the original purchaser owns the regulator and is non-transferable. Proof of original purchase is required.

Electrical components are covered separately under a 2-Year Limited Warranty against qualifying manufacturing defects.

Warranty coverage does not include normal wear, aging, or damage resulting from improper use or maintenance.

Review the complete Regulator Warranty for coverage details, exclusions, and claim procedures.

Yes. Original factory-supplied solenoid assemblies, electrical coils, power cords, plugs, and electrical connections are covered against qualifying manufacturing defects for two years from the original purchase date.

Electrical coverage does not include damage from improper voltage, electrical surges, liquid intrusion, incorrect wiring, physical damage, or misuse.

The expiration of electrical coverage does not affect remaining eligible mechanical warranty coverage.

No. The Limited Lifetime Warranty covers qualifying manufacturing defects, not normal wear, routine maintenance, age-related deterioration, or every malfunction that occurs during use.

A regulator's age alone does not disqualify a genuine manufacturing-defect claim. GLA evaluates the cause of the reported failure to determine coverage.

Warranty service prioritizes repair whenever practical; coverage does not provide an automatic entitlement to a new regulator.

Warranty coverage excludes damage or malfunctions caused by improper installation, incompatible connections, excessive force, incorrect tool use, misuse, accidental damage, contamination, corrosion, water backflow, improper leak testing, or improperly performed repairs or modifications.

Do not use wrenches or gripping tools on the regulator body, gauges, needle valves, adjustment mechanisms, solenoid, bubble counter, or manifold components.

Wrench use is limited to the designated cylinder connection nut when required by the regulator model's instructions.

Normal deterioration of seals, gaskets, O-rings, and other maintenance items is not covered.

See the full Warranty Exclusions for complete details.

Customers should contact GLA before attempting internal regulator servicing, disassembly, or repairs.

External gas connections may be checked after GLA's approval using a suitable leak-detection solution applied carefully according to GLA instructions.

Never immerse the regulator or allow water, soap solutions, leak-detection fluids, or cleaning agents to enter the regulator body, internal openings, pressure-adjustment mechanisms, gauges, solenoid, or electrical parts.

Improper internal testing, disassembly, and liquid contamination can damage precision components. Damage resulting from these activities is excluded from warranty coverage.

All warranty claims must be submitted directly to GLA before equipment is returned.

Email info@greenleafaquariums.com with the following information:

• Original order number or acceptable proof of purchase.
• Description of the reported issue and when it occurs.
• Relevant installation and operating details.
• Clear photos or video when requested.

GLA may require guided troubleshooting or physical inspection before determining whether a claim qualifies for warranty service.

Do not ship equipment without prior return authorization.

See our Warranty Service Procedures.

Repair is GLA's preferred method of warranty service.

When a qualifying manufacturing defect is confirmed, GLA repairs the affected regulator or component whenever practical, including covered parts and labor.

If repair is not practical, GLA determines the appropriate replacement component, equivalent regulator, or other remedy according to the warranty terms.

Warranty repairs and replacements do not restart or extend the original warranty period.

United States: The customer pays shipping to GLA for inspection and service. For approved warranty repairs or replacements, GLA pays standard return shipping to the customer's U.S. address.

International: Customers pay shipping to and from GLA when an international warranty return is required, along with applicable import and carrier charges.

All returns require prior authorization. Do not ship attached or pressurized CO2 cylinders.

Customers pay applicable return shipping for non-warranty service.

Original shipping charges are nonrefundable for approved returns. Outbound shipping charges may also be deducted from refunds on orders that originally qualified for promotional free shipping.

Expedited shipping charges are not reimbursed solely because a carrier delivers later than its estimated delivery date.

No. Green Leaf Aquariums operates its official online store at greenleafaquariums.com.

GLA does not operate official storefronts on Amazon, eBay, Walmart, Etsy, or other third-party marketplaces.

Merchandise represented as GLA equipment on unauthorized marketplaces may not be genuine, authorized, supported, or eligible for the official GLA warranty.

Purchase directly from GLA to ensure product authenticity, current product specifications, and access to official support and warranty services.

GLA does not currently offer a general wholesale or dealer program for most of its products.

We welcome inquiries from established aquarium stores, retailers, and industry professionals interested in potential wholesale opportunities.

Green Leaf Aquariums specializes in planted aquarium equipment, CO2 systems, fertilization, and technical aquarium support. Many customer inquiries require detailed information about equipment configuration, installation, compatibility, or troubleshooting.

Email and text allow customers to provide photographs, videos, product links, and installation details. They also allow GLA to provide clear written guidance customers can reference later.

In our experience, detailed technical conversations often require follow-up instructions and documentation. Written support provides a more reliable record of the information discussed and the recommendations provided.

GLA does not currently staff traditional telephone support for general product guidance or aquarium troubleshooting. We actively monitor email and text inquiries, including weekends when available.
