Thanks for the info. I did purchase the Tertra filter/pump combo. So far it is working great. Here is a updated picutre of the setup. I am still having trouble with the top section. Is there anyway to minimize the amount of algae build it receives? The bottom is very controllable. But the top section, not so much. I did have some fish in this section, but that didnt really do anything for the algae. (so I placed them back in the bottom pool) The setup is in full sun all day with little or no shade.
thanks
