Hey guys. I keep getting told I don't need my mechanical filter. That I am fine with just my hob skimmer and I don't need my sump. I want to start getting some coral sometime shortly and was wondering what I shoud turn it into. My sump is just a basic fluvial filter. There is an egg crate bottom and I was thinking maybe chaeto under that and something lse on top of the egg crate. If anyone has any ideas on what I should do with this think feel free to chime in!!!
