Estimative Index EI - Best Aquarium Fertilizer Package
Our Estimative Index EI Package includes:
- GLA EDTA Micromix (M) - 1lb/bag

- Estimative Index/EI is a planted aquarium fertilizing system based on routine high dosing of dry micro (M) and macro (NPK) nutrients. The underlying principle is to dose more nutrients weekly than the aquarium plants require. This ensure that nutrients are in adequate supply without plant deficiencies; and algae growth in the aquarium is properly controlled through a balance of fertilizing, high lighting, a densely planted aquascape, and a stable CO2 supply (at 30ppm). During an EI dosing week, micros and macros are alternated daily for six days, followed by a 50% water change on Sundays to reset nutrient levels in the aquarium and remove excess nutrients.
- Test kits / nutrient testing of aquarium water is not required with the EI system, although it is recommended to monitor CO2 saturation in your aquarium with a CO2 drop checker to confirm its at 30ppm.
- It's easy to get started with EI routine fertilizing your planted aquarium. Follow the instructions outlined below and review our detailed Estimative Index instructions to make your aquascape a success with daily dosing.

High quality aquarium fertilizer.
Switched from Niloc bags because those bags were just crap. The potasium at GLA is also much higher quality. Also GLA GH Booster is the best I have used, including Seachem. The GLA stuff is just super nice and fluffy. This EI kit will grow plants like crazy so get your scissors ready.

Really good deal.
Good deal on this kit. My tank is large so I have to dose EI I have no other options. Liquid dosing would be stupid expensive so I use this. This is my 4th kit from GLA and its always perfect.
-
Super happy!
Very happy with my new EI bags kit. This is a refill from my previous kit from a year ago although I was dosing PPS at that time. My tank is a fast growing duct tank and I use T5HO lights from TEK so its super high PAR and I felt it was time to start EI dosing. Its been a banger improvement. I do perform very large water changes on Sunday with this EI system and I feel it works better for my system than PPS. My plant load is massive and thick so I need a little extra of everything. The bags are very nice, they stand up and make it easy to dose daily without trouble. Love these bags!
-
Worth every penny.
I dont know why folks buy that liquid stuff. You can make gallons of liquid fertilizer with this alone. Use that fertilizer calculator and your set to go. If you cant use a calculator thats fill in the blank this product is not for you. If you want t grow plants to maximum ability on the cheap, this is for you.

Great planted aquarium fertilizer system.
Ive never used this type of fertilizer before. I always used liquid but felt my tank was always lacking so I gave this a try. I noticed improvement in only 3 days time. Dosing is easy and quite fun. My plants are much more happy and that makes me happy:)

E I. Fert set
As always, gla is rock solid. I have used these in the past with good success. Next Time though, I think I’ll spring for the jars instead of the packets.

Love GLA fertilizers
Fast shipping and super great service. This is my 3rd EI kit with GLA in the last 6 years, totally happy and always a return customer.

My plants thank you!
As a beginner I was very skeptical if I would be able to use dry fertilizers in my aquariums( I have 3). The first thing I noticed was how quickly my plants responded to using GLA fertilizers. After only a few days of dosing I was shooting myself in the foot for not going this route a year ago. I would have saved myself loads of money not buying these all in one fertilizers in premixed bottles. This is so easy to do and will cost you pennies compared to liquid dosing. If your just starting out dont hesitate to go with GLA fertilizers because its super easy. It also cost next to nothing compared to liquid fertilizers, what a waste of money.

EI package
Its definitely worth trying. My plants are growing like crazy. Even new plants act like nothing has happened and just start to grow and be happy. Im currently using co2 around 20ppm and everything is well balanced now. I was trying to use seachem products and they were not working very well at all for me.
-
Almost perfect bundle
This is a great little bundle to get started with ei dosing. It includes macros and micros, as well as easy to follow dosing instructions on one of the bags. The only thing that could improve this bundle would be a set of measuring spoons, dosing for smaller tanks is as little as 1/32 of a teaspoon a day, it would be nice if tiny measuring spoons were included for these smaller ammounts. I used larger measuring spoons to make a dilution with water which works, but dry dosing is probably easier. Overall I would still highly recommend though!

EI pack
Better packaging in black bags than the older clear bags. Ferts will keep longer.
