Remove the Bio-balls! They are Nitrate magnets. If you really want to keep them, you'll have to clean them occassionaly. Recommendation is to remove about 1/4 worth at a time.

Ok what should I use in place of the Bio Balls?

I was pondering a closed loop with the second pump using a canister filter with carbon and filter cartrage. Any thoughts?

Filter socks? You could remove and clean those easily!

Just a few more questions for everyone.

I have been having trouble finding filter socks where can I get them?

I am assuming there are diffrent mesh sizes what size is appropriate for a 75 gallon FOWLR?

Should I turn the sump into a refugium?

What do you put in a refugium?
