I think that a good thing is to make a brief summary of my system. So, I have been using DVH biopellets for about six years, firstly np reducing biopellets, then aio and now I came back to np reducing biopellets. I add biogro 123 marine bacteria and once in a while Colombo bacteria after each change water (w.c. about 10% weekly). My tank has been bare bottom for about two years. I used to have something like balling method but I came back to calcium reactor several months ago and added also mixer with limewater. There are real reef rocks in my tank. Lighting, of course ATI 10 x powermodule with 4 channels. T 5 combo: blue plus, coral plus, ultra royal blue, blue plus, giesemann pink, aquablue sp.,blue plus, ultra royal blue, coral plus, blue plus. Salt, microelements and aminoacids from Colombo - don't confuse with Colombo lieutenant ;-). I feed my fish twice daily, corals twice weekly. Think that's all.
