Whoa ...well...I'm kind of the antithesis amongst many here, however still believe in the basic parameters of reef keeping. My salt is Instant Ocean Reef Crystals, however, many others are just as good. My lighting is actually quite low for a 90 gallon, 2 T5's and a 54 watt Fluval LED , programability of Dusk/Dawn is the biggest thing with a slight bump to daytime. I don't dose, never have. Water changes 2-3% every 3-4 days keep my elements in check. If you want PM me, and I can send you some images....I'm not suggesting my methodology, but just saying it works for me....no skimmer, no fuge, no cannister, no sump.
