My tank is 125 gallons, I have every single piece of equipment, skimmer, UV, power heads, T5 lighting, Nitrate control equipment but I don't have a refugium.
Parameters for the standard stuff read fine, but I use a standard testing kit.  Calcium I don't test but I add it without failure per the instructions on the bottle.  I've only been keep corals for 3 weeks.
Type of coral I could not tell you because the pet stores confused me, they each name everything differently.  The coral with the mucus is like a plate and with light little fan like heads come out and extend towards the light, it's green.  The disintegrating one is a on a branch type piece of rock and with light each polyp grows wo make what seems to be on large coliflower.  The color is brownish.
