Just got 2 bags of sms for my new 125g?
I just picked up two bags of sms charcoal for my 125g and have a couple questions. Should I put a thin layer of moss under it first? I now have a gravel bottom in my 55 and my air stones are covered. With the sms how do you have the air stones hidden if the sms is so light? Or don't I need them in a planted tank?
