Yeah sorry for the lack of info.
I have a 90gal reef ready tank, 20 gal sump. 100 lbs live rock. icecap 660, 2 x 50/50 2 x actinic 110 VHO's, 440 total watts. Hang on bakpack skimmer as well as another skimmer in the sump. I am dosing only Combisan once a week as well as C-balance (once a week at lights out) and kalk, (never at the same time)
My corals are all soft, polyps, mushrooms, tube worms and anenomes, some sponges. Nothing spectacular, but wht i have thrives.
Its been up and running for 5 years. Use to enjoy tons of coraline pink and purple algea when it was all in a 55. I switched to the 90 about 6 months ago. I havent wintessed a noticable loss of coraline algea on the rocks, however i used to have in growing on the glass, powercords..everything. That when it was in the 50, which was NOT reef ready, i.e. no overflow/sump.
Maybe i just need to give it more time, i would like to know how others are dosing their 90's though.
