After a couple days of my zoas and a few other corals not looking so happy -retested nitrates and phosphates.
Phosphates at 0.4 -not bad -nitrates -uh -0.3 -this was a few days after testing around ~3.
At the same time I see a cyano bloom-where it was centralized on the sand -it has now
Appeared on rocks, rear wall, and the sand. I assuming the cyano has made good use of the nitrates and is feeding the cyano.
My thinking on this -is black out the aquarium for 3 days and massive water change (10 to 15 gallon a day) ? Let the experts weigh in if there is a better solution? Should I be dosing nitrates back in during those three days?
Bah.
