    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.

    My plants thank you!

    Posted by Megan Short on 12th Jan 2020

    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

    Posted by Robert Hoffmann on 18th Apr 2019

    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

    Posted by Jesse on 24th Mar 2019

    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!

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