the cube was set up in Nov but was done with water and live rock from my 120. I only had one fish in there and I feed him every other day, so I know it is not that. Do you think I need to cut down on just one dose of 1/8 tsp? like half of that once a day? Oh and I do a 5 gallon water change every week. The wierd thing though it happened right after a water change too. I blew off all the rock and in the back of the chambers in the Biocube, which I have not done before this time. That could have caused this bloom of white fuzz with the vit C.
