Tank has been cloudy like this for almost a week now. Coral and fish seem to be doing fine I have my power head and return aimed at the surface for more disturbance. Just seems to not be clearing up. 20g aio, included filter sock with cut up filter floss in it changed out every couple days. Not sure where this came from, nothing has died or changed, only feed about half a frozen cube a day and do it slowly as the fish eat it. Weekly water changes 20%. Tank is about 2.5-3months old. Test results are from a few days ago. It doesn’t seem to be improving, should I invest in a uv filter?
