I have a 90 gal tank with a wet/dry for up to a 300 gal tank. The wet/dry has a built in protien skimmer, then the water drips down threw media balls into the sump, and back into the tank. I had a huge algie problem, and the tank wasnt very clean. I took out 1/2 of the media balls, and put 3 12" / 14" media bags. 2 filled with carbon, and 1 filled with a carbon,phos mix, I also added a phos. pad on top of the media bags right below the tray with the holes in it. So basically the water drips through the media bas before it reches the media balls and retuns to the sump. I also switched to a 1300 gph pump up from a 400 ghh pump. My question is will this set-up work? The water is crystal clear. Its been over 1 month now and the water is style crystal clear. I used to have to do at least 1 water change a week. Do you see any problem putting the media bags over the media balls? Also I no longer get anything in the collection cup on my protien skimmer? Is this because the water is already clean, or did I screw something up? Right now I just have ciclids in the tank, But I am going to be switching to a saltwater tank as soon as I can aford a 200+ gal tank. Will this setup work on the saltwater tank also?
