Overflow?

We bought an overflow box today....our tank is not drilled so we bought one of these acrylic things that you hook up to a sump (we have one of those for it...) pump the water back up and BINGO-no more scum on the surface of the water! Looks good! Bit noisy and needs some tweeking from Ken but it does the job! This tank will be back to the beauty it was....and algae??? What algae. I gotta say it sure taught me a lesson in cleaning my tank properly. Every night the tanks get turkey basted, scraped etc. No scrimping unless we are away. Also bought a couple of new friends for downstairs. I think that tank is almost maxed out! Now lets start adding fish to this one again!
