My pump for my media reactor locked up due to Ca+ build up so I wasn't running GFO for a couple of days. Didn't notice that the media wasn't being fluidized. Nothing seems upset, but I'm sure my PO4 came up some.
I've also cut back my MH photoperiod to see if that helps my corals color up some. My LFS suggested they coud be bleaching given the amount of light I am giving my tank--500w MH and two T5 suppliments in a 55g. I've not checked my PAR but I will soon.
Until next time,
Love the addiction!
