What clients say

'best of the best'

Green Leaf Aquariums is my go-to place for high-quality CO2 regulators. I’ve never used any other type of regulator on my tanks and don’t plan to any time soon. These regulators are built to last and really are the “best of the best”. The customer service that Orlando provides is AMAZING to say the least. I have never had to wait more than an hour to receive an e-mail response from him, and most of the time it only takes a matter of minutes (i swear i sometimes wonder how he even has time to think about what he’s typing!). This guy really cares about his customers and i can confidently say that i have never seen such impeccable customer service from any other company.

Don’t believe me? Try it for yourself. Order something from GLA and i promise you won’t be disappointed.

Thank you for all that you do for the hobby, Orlando and GLA!

'I couldn't be more pleased'

I just wanted to say thank you I received my order today and I couldn’t be more pleased about the care taken in packing my shipment and the quality and craftsmanship of the products ordered. This is the second time I have ordered from GLA although my account will only reflect this most recent order, my first experience was ordering Cal Aqua Labs 17mm Eflux and Influx filter pipes. I look forward to continuing to do business with your company and will praise both your customer service and quality products to everyone concerned with aquatics.

'quality at all levels'

'I wanted to let you all know how impressed with my first orders of ferts and a CO2 regulator. Everything was packed very professionally. Every corner taped, all labels perfectly symetrical and very clear instructions. I order on line a lot and your company is at the top of my list for showing pride in your work and quality at all levels.'

'I’m just starting into planted aquariums as a hobby and Green Leaf Aquariums has made it a smooth ride. This is by far the best customer service of any web site I’ve ever ordered from or quite possibly any business I’ve ever delt with. I will definitly be ordering the rest of my parts from GLA. Thanks again for all the hard work guys!'

'the most helpful and knowledgeable person I’ve ever talked to for customer service'

I was trying so hard to create the perfect planted tank that I had imagined in my head but I kept running into problems what seemed like every step. I had problems with correct fertilizer dosing, CO2, circulation, you name it. Orlando has answered all the questions I’ve had and is probably the most helpful and knowledgeable person I’ve ever talked to for customer service. Thanks to his help, I think I’m beginning to get the hang of it and my plants started pearling for the first time.

'you guys saved my planted tank'

'I just want to say thank you. You guys saved my plant tank. I’m new to the planted aquarium world and was either giving to much fertilizer burning the plants or not enough and yielding little to no growth. I now have your regulator and pps pro package and I got to tell you it’s off the charts!!! The regulator is fine tuned to perfection and the pps Fert method takes the guessing out of the equation. Everything is vivid green and pearling like crazy. I will never use another Fert method again. Again thank you guys for your professional advice and exceptional products.'

'these guys are the best'

'I’ve been keeping fish since I was 7 years old, since then, I’ve always put plants in my aquarium and tanks. Over the years I’ve lost interest in the hobby due to a lack of equipment available in my country to support my interest in planted tanks. I did some searching and found GLA, I must say, these guys are the BEST. They answered my million and one questions and guided me along the way. I am a very brand loyal person & I’ve found a brand i’ll stick to!

I have nothing bad to say about these guys, I must thank them for all their help & i’ll definitely buy from them again!'
