Hi everyone, I got my 90 gal. running, 100lbs of marco rock,140 lbs, marco sand, added about 10 lbs. of live rock and sand about a week ago for cycling. I am testing water everyday and amn. is slowly going up. I have no filtration going, but a closed loop and vortech for water movement. My ATS is almost complete just some plumbing. Couple things first. When should I start running my ATS. 2nd, a film has begun to form on the surface What should I do? 3rd, I am researching clean up crew, Should I skale down the amount in the crew because of the ATS. My ATS is horizontal, made with black acrylic, 13"x19" with screen 12x18. there are two boxes, one with the screen and flow the other with 4 CFL 27 watts each. The two boxes are stackable for easy access. The flow is gravity fed from 3/4 line going to two 1/2 loc line with flare nozzle which will drain into a sump with sand and rock. I have a skimmer that I do not want to use. Any help or comments would be great.
