Thanks, would they do okay w/ my current livestock? I have a Volitan Lionfish, an Engineer Goby, a Yellow Tang, and a Kole Tang. Is this too much bio-load for a 75 gallon? Parameters are Amm-0 Trite-0 Trate-0 Phosphate-0 Calcium-600. The tank is fully cycled, has a DSB (120 lbs), a a wet/dry filter, here's the order. 1. An overflow collects the water which flows downwards into a 2. tower, mine is filled with a prefilter, phosphate pads, a mesh bio-roll, and 1 gallon of bio-balls, or 74 balls. From there my water is sucked into a 3. SeaClone 100, and after it leaves the skimmer it is forced through 4. heavy-duty phosphate pads, and then is 5. pumped back up by a 750 gph Mag Drive pump. I also have a Magnum 350 Pro w/ 2 Bio-Wheels. The canister is filled w/ Nitrate Reductor. I also have 2 Hagen 402 powerheads. I have 125 lbs of LR, and for lighting I will have, in a couple of months, a MH/VHO system, supplemented by PCs. 2 175 W MHs 10000K, 2 110 W VHOs, and 2 55 W PCs. Are there any problems in my setup that would prevent me from getting a King Angel, if so, please let me know.
