Ph crash, cloudy water

[DoINeedAName?]

Please help, I had a ph crash in my saltwater tank and the water is very cloudy. I have already lost two fish and think I’ve lost two more but I can’t find them. My Nem is dying too and I don’t want to lose my urchins.

Open a window, add an air stone, increase surface agitation. You probably have a bacterial bloom which decreases oxygen, decreased oxygen also lowers Ph.

No, I think it is ph, the cloudy will be a bacterial boom and it depletes the oxygen, points the heads to the surface and checks the ammonium

1. I’d suggest a possibly water change (25%). At least get the saltwater premixed when time permits.
2. Increase water flow/agitation (per above).
3. Fairly certain that others more knowledgeable will want to know your water parameters, etc.
4. What (if any) tests have you run, ie: PH, nitrates, alkalinity, salinity, etc.
