Ok so I just finished setting up my ats yesterday night on my 75g w/15g sump. I removed my filter floss, skimmer, and carbon from my system. The ats is hooked up to my drain from my display. the return is more than 545 gph at 7ft and I have it at 4ft. On one side of the ats I have 150 watts of energy saver spiral bulbs. They are rated 23watts but equivalant to 75watts. So my question is do I need to do more to my ats or am I ok. I made it get rid of my hair algae problem and waiting on results. Oh yea the screen size is 10widex13long and I ruffed it ip pretty good.
