I was out on a pet supply run today and picked up some root tabs-- Pond root tabs-- for my 40 g planted. Are these gonna be okay to use? It is Aquarium Pharmaceuticals Pond Care.
I dont know whether they are or not, but when I found those a bunch of people advised me against using them. Something about Urea, check the ingredients.
how about using very small pieces of the stick fert meant for indoor house plants? I put about 3/8" of one under one of my plants but have not seen any dramatic difference yet.
