Ok.. I had problems with cloudy water.
Since it was a new tank and high light and not heavily planted yet, for almost a month I thought I was fighting green water algea. I was doing large water changes every few days, and it kept coming back. I borrowed by cousins 'green killing maching' UV bulb and did large water changes, and it kept coming back..
Then finally with nothing left to try, I figured I would let it go, not do anything about it and see if it can just run it's course. After about a week and a half the water wasn't really looking green anymore, but BROWN!
I was leeching dirt into the water. The petco sand was too light and/or it was leeching from under and behind the DIY background.
I drained the entire tank and got rid of all the substrate. Now my substrate is MGOCPM with clay capped with black blasting sand. I also got rid of the background.
I also added some limestone from around the pond behind my back yard. The look I am going for now is a nice carpet and midground with stems in the back to cover the overflow a little.
