I have been having a hard time with my tank.. It has been up and running for a week and three days, I started getting diatoms in about a week, but they are taking over, Im not sure that they are diatoms, or something else, stuff is growing on the glass so fast every day. its looks like hair, its not fuzz and it comes off really easily, it just looks like little short hairs are growing everywhere. I have some snails and crabs in there now but it doesnt seem to be doing much. Should I run some carbon or GFO?
