Hey... I have a 30 gallon tank with UGF (under gravel filter) with 18 fish and i'm planning on doing a full tank clean out.
When i take out my fish what should I do?
Where do i put them?
I need some advice on what to do and what to watch out for?
This is the first time i'm doing this and the tank really needs it.
