I've avoided putting anything in the main tank but I have some areas that are low flow and 'I think" I have too many soft squishy sponges init. I know that powerheads are suggested for low flow areas but how many do most folks have in their tanks? Also, how big of a powerhead should I get? Can I place the powerhead behind the LR
to hide it (my LR
doesn't lean against the back glass)?
Maybe some sponges are ok but I don't like all of the ones I have. Should I manually remove them?
Jeeze! You'd think I was playing 20 questions here or something
