Yep, came out cleanly last month, but fused and cracked this month. Not sure what caused it, but yeah, I just have a bunch of coralline algae in the tank without any other sort of algae. I have to Flipper the glass once a week, but that's not bad considering how much I feed daily. This seems to be an issue with the older wet sides. The QD wet sides were supposedly rebuilt to address some of the issues that the regular models were having. Ecotech shipped out replacements for the wet sides, if you were having the same issues, as long as they're under warranty. My pumps were built back in January 2013 so they've been out of warranty for awhile now.
