QT tank cloudy

I don't have direct sun light hitting the tank. The room is pretty large but has natural light. Not directly on the tank.
 
What meds are currently in the water? Does light from a window shine into the QT?
It did, they are rebuilding the house next door (which we might actually be buying) so when it was just framed out, the sun would hit off the wood,making it very bright, if that makes sense. I shut the blinds and it seemed to have helped. There is only copper safe in there right now. The surface has some foamy bubbles on the edges, which I thought was strange.

Probably a bacterial bloom from all the light. Copper in the water would have just exacerbated the problem.
 
Don't know about the blanket part :D ... but whatever keeps the light out.
Haha, I had a lot of brown algae on one all over my rocks and glass one time, my tank was in a room where light was abundant even with the blinds closed, so I took a towel and tossed over it for two to three days, then took it off and the rock was bright white and very clean looking:D
 
I just did a large water change. And kept doing it until it cleared up. But i did a 75% water change and then 4 days later did a 50% water change.
 
bacterial bloom won't harm your fish, when your done with copper treatment. UV sterilizer will clear it up in 3to5 days. I had this happen to my QT while I was waiting for the main tank to go through its fallow period.

So you can use a UV sterilizer on a qt?
 
Yes it is.
I'm going to vote it as that. Same as at the beach, white clumps of foam= protein based waste=) I sometimes volunteer down at the marine science center on Tybee island GA, to help them out saving injured fish, turtles and what not, all kind of stuff we find. And that's one of the things I learned, but then again that doesn't exactly mean that's what's in your tank, but being your water is cloudy, I would assume that's the answer. The foam is in the QT tank right?
 
Yes it is is QT. Is there anything I can do?
If it were me and I kept doing water changes to no avail, I would just change the water completely. 100% I'm sure there are other ways to beat this but being it's a QT tank, I'd change it all. Or like said earlier, bigger water changes.
