I have been wanting to buy a white SpecV for a reef setup. Did you keep the stock pump? What kind of filter media are you running?
Filtration is only live rock and and the mechanical sponge/carbon that came with the tank. I use media bags and buy my own carbon only run it when I need to. It has some bacteria media to but I would just use that for some GFO or something if phosphates get out of control.
Did swap out the stock pump with a minijet 606. Light is a coral compulsion PAR 30 18k bulb with 90 degree optics.
