I have a 75gal Tank with a 75 gal sump (( Has like 50 -55gal water ))
20gal fuge and no skimmer yet.

Hello,

I think the answer is pretty clear.

ummmmm answer for what??? Im confused?

Hello,

The fact that you are running a system without a skimmer and talking about water quality issues. You need a skimmer.

definatly get a skimmer, carbon needs water to be ran thru it in order for it to work. some make a little shelf under the drains in your sump but its wise to either use a filter sock on the drain or make another shelf just above the carbon shelve. clean it regularly. canister works as well but a pain to always take apart. BLACK DIAMOND is good and carbons longevity depends on water quality but lasts longer then 48hours. If you have lots of nice SPS becarefull not to burn them. when starting carbon it will make your water clear so reduce light by a few hours. just like acclimating a new coral. they will bleach if you don't. I've seen/read were people just start carbon and wonder why they get instant bleaching.

oh i have a skimmer its in the mail got a turbo floter :) But some people say u dont need a skimmer and some do. The main reason i want carbon is to keep the smell down cuz my tank is so new that the water isnt pretty
