What more could i do......(NEED HELP!!!)

[Renegade]

just a thaught what are you adding / using maybe chemicals you are using are mixing causing an ill effect. ? Is your rock very pouris ?? Stick with it. I wish i had half the equipment you have, i unfortanitly cheaped out with i first got into the hobby but i never had alge or death problems but with corals that were a little more finicky. Now i'm in process of upgrading to new system.

Is the tank covered with a glass lid?

The reason I ask is it could be an O2 problem. During the day things are fine do to photosynthesis but at nigh O2 levels could drop. This could be a problem or it could be the resulting drop in PH.

All i add is C-balance (A/B Calcium and alkalinity solution) and some liquid vitamen and foods for inverts. Oh, and sometimes some MG, but only once per week at manufacteres instructions.

What liquid food and vitamens? You probably don't need to add any liquid food at all - even DT's can pollute your tank and right now it seems you are having problems so I would discontinue for a time.
While you are checking out the "clean freak" also check to see if anyone has been using insecticide anywhere around the tank or even in the house. I know I had this problem a couple of years ago and caught my son with the Raid can!
