so I changed from gravel to sand, its amazing how much filth is kept in the gravel, I had not idea, the first pick is when the gravel was taken out and was all black, I had to put two filters on there and then clean them again to get it to look nice again but it looks alot better now, and I didn't change the water add or take any out.
