How much Filtration is enough?

[saltguy21]

I have a 120 galon fish only tank with a moderate amount of fish...nothing very big. I was wondering how much filtration I should have. I currently have a sump system, a cpr backpac with a skimmer, and an emperor 400. I also have 2 powerheads ( 1 on each end of the tank). I want the water quality to be good but I notice alot of air bubbles in the water and some debris as well. I also have 44 gallon tank with an emperor 400 only and the water quality and clarity are much better.Any suggestions would be greatly appreciated.

More the better. How much LR/LS you have? that does a major portion of your filtering.... I dont think you can over skim... that CPR skimmer might be to small for you tank. I also dont think that emperor is doing much your tank, what are you params? if you have 0/0/0 then your set up is working just fine.

Acpr Back Pak Is Only Suppose To Run On A 60 Gal Tank. Plus It Is Not That Efficent Of A Skimmer Compaired To Others That Even That Mfg Makes. Since You Seem To A Fish Only System Is Your Sump A Wet Dry Filter? Is Your On The Tank Or Sump. You Will Get Less Bubbles If Skimmer Is On Sump.

How Long Has Your Tank Been Running

cpr is on the tank. I have a wet dry sump but the water level in the sump is way to low to have the skimmer on it.

 

[saltguy21]

had 120 since last may... converted from a 75 gal that was up for a year.

Usually Nitrite Is A Sign Of Not Enough Filtration I Would Suggest A Larger Skimmer

Another option for you would be to run some ozone into the skimmer you have. It will clarify your water, get rid of your organics and would really give a kick to the skimmer you have. Their are methods for running ozone that can allow you to avoid any problems and enjoy it.
