I've had this tank set up for about 6 months. Recently the tank got cloudy after I had been treating it for ick for about 2 weeks on and off. It all started with a few clown loaches that I got and they kept getting ick, well anyway the ick had cleared up and the water was cloudy for some reason. I thought I would just wait awhile and see if it cleared but it's been about a week and it hasn't. I did a water change and it didn't make a difference, and one of the clown loaches died a few days ago. All of the fish look ok, but it's cloudy. All of my readings came out normal for the water, any ideas? Thanks.
