These are in a 14gl frag tank that is in sump line with display. This is the 75gl display.
Planning to move to a 150gl very soon.
Lighting varies depending on how I feel. Sometimes PC, MH and/or T5. Temps stay stable but does change sometimes +/-5 degrees. PH swings from 7.8 to 8.5 but I am getting it moreso under control since I did a DIY PVC kalk reactor. Flow in the diplay is sump return from a Quietone 3000 that splits to the frag tank (only flow in there) and the display has two maxijet mods.
Salinity stays about 35, really there is a lot of changes due to simple set-up and sometimes laziness. I always use Reef Crystals and do water changes when the corals start to look tired (anywhere from weekly to 3 weeks). I feed corals and fish daily. I do have a large refugium. Basically I don't do anything different from anyone else, though I do and always have without fail since I started reef-keeping back in 92, daily dosed Kent's Iodine, Moly/stront and liquid calcium.
Let the arguments begin! lol. Sorry to those that don't think dosing is good, but I do and always have and have always had great tanks.
