Hi, so I have a biocube 32 that is almost 5 years old. I am just now getting comfortable with testing water parameters and caring for coral so in the last year I have built our zoa, frogspawn, hammer, and torch gardens (all in their own respective areas with no contact to one another). recently I have been noticing that when mu blue light turns on, my corals tend to be super full and have great pe but then recede and I have no clue why. My parameters are dKH: 8.9; Ca: 430; pH: 8.2-8.4 (API); NO3: 10 ppm (API); Salinity: 1.026; Phos: 0.14. I run my lights for 6hrs blue, 4 whites, 8 hrs blue, and no light for 6 hours. Can anyone shed some advice on this problem?
