Iron sand and adding fertilisers
Hello, please forgive me, I am new to keeping planted aquariums and new to this forum. Please let me know if I have posted correctly.
My tank has iron sand and fluvel plant substrate. A bunch of crypts, Anubis, val, Java fern and big fat goldfish. (Yes they leave the plants alone)
I want to start adding fluvel plant micro nutrients to it, but I am concerned the iron in the bottle and the iron sand will be too much for my plants but also my fish.
