Where has this been!
Awesome stuff, GLA! This is just incredible and thank you GLA for the very detailed write up and instructions. This is a game changer in aquarium fertilizer options. Pay attention people, this is a complete macro mix and they provide you easy mixing instructions to create your own liquid stock. Blown away! Can’t wait to try the micros when my old Plantex runs out.
