Ok I had some cyano going on. So I siphoned a lot of substrate and cyano itself off of some rocks. After this my Uv bulb died and day later a bacteria bloom. Today I bought a bottle of fritz zyme 9 and a new uv bulb. Should I just turn the uv on again? Or turn that abs the skimmer off and add the bottled bacteria ? Or is this too much bacteria without enough oxygen in the water??
thanks
