My coralline algae had been growing like crazy over my LR and glass for many months. But recently had started to recede and turning to a green and whitish color. I haven't made any changes to the water chemistry apart from the regular dosing of calcium and dKH. So what could be wrong?
My water parameters are Ca=450, dKH=11, PO4~0, PH=8.2, NO2=0, NO3=25. I know my nitrate is a bit high, but it has always been about 25 when my coralline algae are growing fine. I have 160W of PC lighting. I have not changed salt and is still the same batch of salt for the past few months.
