I have no idea what is causing this but it has been going on for 2 weeks or so now. I have searched the internet and the two options seem to be algae bloom or bacteria bloom. Every morning the tank is very cloudy. As the day goes on, the water clears up. Then the next morning it is cloudy again.
So what would cause cloudy water in the dark with lower co2, then clear up with light and co2?
I am running 2.9 WPG for 9 hours, pressurized co2 at 30 PPM. (Turned off at night). Fish load it light for a 75 gallon.
Water tests show the following levels
Ammonia 0
Nitrite 0
Nitrate 5 PPM
Phosphate .5 -> 1 PPM (Hard to tell for sure on the color chart)
I am using the EI fertilization method.
Looking at the aquarium from the front it shows some cloudiness but if you view the length of the tank by looking into one end, you can not see through the water. This cloudy water was triggered by a large trimming and water change a few weeks ago. Maybe it is a bacterial bloom but It is interesting how light and Co2 make it go away.

Ok, I actually figured this out a few weeks ago. I added a HOT Magnum filter and DE powder and the tank has been crystal clear since.
