Canister in sump. Yes or No?

Replace the PH in the tank with the can. tubes.
 
I had the same thing in my sump, a layer of brown goo in the bottom. I added an airline with a 12" airstone to try and get some turnover of water within the sump. Maybe putting a small powerhead to add some current would help.
