Cloudy water?

[tmccaff]

I just came back from vacation and my water is cloudy. What would cause this? I did have auto feeder on twice can it be food? I did a small water change and added carbon. My mastertronic is saying OLI 7 which is bad I am guessing since its supposed to be zero.

Could be bacteria, or algae. What are your parameters? How the health of the inhabitants?

Depending on the cause, adding UV would help in the case of bacterial blooms, or homemade Coral Snow can also help as a catch-all
