For the last 3 weeks I've been going through an annoying cycle. At lights on my water is slighly cloudy - front to back view is ok but looking down the tank is distinctly "hazy". After a few hours of lights and CO2 the plants are pearling nicely and the water is crystal clear! Next morning the cycle repeats.
50% water change has no effect on this, so I added the JBL filter pad to remove super fine particles, but no difference. However, it came out green so I think I'm up against some kind of diatom algae. I guess it will either just pass, or I have to invest in a UV unit...
But what's going on, scientifically? You'd think they would bloom more in the light. Is the CO2 driving them off, or the O2, or do the plants remove trace ammonia, or something more complex?
