Q on Sump?

[West1]

My 100gal sump on my 300gal tank used to be really dirty in the bottom. So I added a powerhead to clean it up and I love it. My sump is super clean now. I dont see any problem with it. You have to add a powerhead with a sponge on it though. Otherwise all of that dirty stuff will just go back into your tank.

Thanks, Im going to try this first

I would suggest doing this during a water change or when you have your pump turned off. So that the sponge has time to pick up all of the small particles or they will just go into the tank
