The tank was getting taken over by halimedia and some caulerpa. When all the work was done, there was almost a whole 5 gallon pail of algae.
Your tank looks fine to me, don't sweat the small stuff. Everyones tank has to find an equilibrium, and every tank has a different equilibrium. IMO you worry to much about the small things, and never stick with anything long enough to find out if its working or not. (Sorry that sounded kinda harsh, but it wasn't ment to be.)
