I've been thinking about dipping my feet into corals, i have a very well established 55 gallon system, my question is what things do i have to change?
Tank 55 gallon w 30 gallon sump
Temp: 77 degrees
Filter Media: GFO
Skimmer: Aqua C Remora w Mag drive 3
Trace Elements: None I think
Salt Mix: Tropic Marin
Lighting: T5HO 36" light fixture ( Midday geismann bulb 1 Super Atinic geismann bulb) and 1 Atinic Ecoxotic Stunner Strip
Nitrate: below .10 ppm
From what I know now I'd have to upgrade lighting, salinity, and calcium, test kits?
