Hmmm... Seems wierd. I've had mine running for about 3 weeks now and I am getting the beginnings of algae forming on my glass, plants and driftwood. The glass isnt an issue, as I just can go at it with a scrubber. And I have avoided doing too many water changes as I'm just getting done with my cycle. I've mostly just replaced evaperated water and kept a close eye on ammonia and nitrite/nitrates... I'll start with more regular water changes now that my tank is more established and see if that keeps everything in check.
Thanks again for the info!
