Cloudy water - What is going on.

Ok this seems stange to me.
I did a large trimming and water change about 2 weeks ago. This is when this all started.

Every morning the water is very cloudy. So cloudy that if looking through the tank end to end, you can not see through. I have tested Ammonia and Nitrite, both are 0. Phosphate is .5 and Nitrate is 5 PPM. I keep my co2 at 30 PPM during the day, and shut it off at night.

It is cloudy, not green. As the day goes on the cloudiness clears up and is essentially gone by the time the lights go off. Then the next morning it is cloudy again. Repeat.

This seems to be related to the Co2 and light levels but what would cause cloudiness to go away with light and co2, only to have it return when the co2 and lights are turned off?

Since the plants are not making O2 at night, could the cloudiness be lack of o2? I have never heard of that. Should I bubble some air at night?

Thanks - I hope some else has seen this.

Could be a bacteria bloom, if so it will go away.

The thing is its clear by the time the lights go out, and cloudy by the morning. Bacteria would not bloom nightly and go away daily would it?

I remember when my GW bout first came on, and it looked like a bacterial bloom. There was no greenish tint to it at all. But it went away at night and came back by day. So I knew it had to be, but I didn't believe it. Then eventually (it's hard to tell exactly when because it happens gradually) I looked at my tank and there was no longer any way I could deny it-- the water had taken on a greenish tint.

So to the store I went, to buy a UV filter, and I lived happily ever after...
