Ok I am going to give a heads up on what is in this 90 Gal tank so you all know. Protein Skimmer made for 120 gal, canister filter with a UV Sterilizer which I am not using at the moment (using canister filter but not the UV) the canister filter has bio balls, ceranmic noodles activated carbon and pre filter pads, 60 lbs of live sand, 40 lbs crushed coral, 85 - 90 lbs of live rock, 4 Hydoras, 1 flame angel, 1 koran angel, 1 blue/green chromis, 1 peppermint shrimp, 1 cleaner shrimp, 2 porecelain crabs, 2 pom-pom crabs, 2 emerald crabs, 1 shavers (painters) brush, 1 flame scallop, 1 gold banded coral shrimp, 100 snails, 125 or less crabs, 1 anenome, 1 250 watt heater. We feed our fish every other day with a 1/2 a cube of mysis shrimp. Chemicals we use are Reef calcium, reef builder in our refill water, Reef Calcium advantage that we use in our refill water every other time, reef complete, reef plus which these are all by Seachem. We have a RO/DI system which is a 6 stage unit. For testing our tanks we use API Master Testkit. We do gravel vacing and water changes every other week. The lighting fixture we have on the tank is a Nova Extreme T5 with lunars which is 430 watts with 8 bulbs (4 - blue atinic and 4 white). We use Instant Ocean Reef Crystals. We have airstones, heater and a recirculating pump in our 33 Gal garbage can that is brand new that we store our RO water in when we need it. Our lights stay on for 12 hours and then the lunars are running 12 hours as well.
Any and all help is appreciated to put us in the right direction.
