damn, weird thing is that i don't have any micronutrients deficiency using it, or maybe the substrate do the jobHumidity means water. Water is the prerequisite to microbial life. Nutrients aplenty, obviously. Micros-blends contain organic compounds. Brown colour seems to indicate that your iron oxidized into Fe(OH)3.
Throw it away, now it's worthless, and potentially damaging to you tank.
so in my trace mix, iron is the only that is bad or every other micronutrients are useless now, because i have a bottle of easylife ferro ?My recommendation concerning micronutrients (not only for you): Use ordinary salts (sulfates, chlorides) for Mn, Zn, Cu. You wouldn't need any 'stabilizators', meaning organic compounds. Such salts are stable eternally, dry and in solutions (but better not blend them with anything, just DI water!).
Iron is the only element where chelation makes sense. Get chelated iron and keep it separated from anything else. Keep in dark the stock solution, and the powder dry.
Perhaps you'd notice no micronutrients deficiency without it as well, except for iron...i don't have any micronutrients deficiency using it
... which you have in separate solution. (I don't know the formula of EasyLife Ferro, I only guess it's a blend of iron chelates.)i have a bottle of easylife ferro
