Well here goes... Its a 55gal. with 2 hagen powerhead 402's, 2 65watt smart lamp power compact florescents, 1 48inch 10,000k coralife florescent, aquaclear 500 filter, and a turbo floater 1000 multi skimmer. I have about 35lbs live rock which is covered in coralline algae..nice purple. argonite reef sand for substrate.. I'm considering changing my filter though.. Ammonia is 0, Nitrite is 0, and Nitrate fluctuates from 0-20ppm.. Partials are administered twice a month at about 15 to 20% each time. Oh I also have an ebo-jager 250watt heater which maintains my tank at about 75-78 degrees.. I found this area of temp. seems to work well for me. I use coralife sea salt for my mixtures... Hope this helps in deciphering wether or not I should try certain chems..
