. This sounds more like an algae (possibly diatom) bloom. Is it on the sand and rocks as well? How hard is it to scrape off?
Since the rocks were cured, it is hard to tell. Sand looks slightly green and the algae is just starting on the side walls, but just lightly. I haven't tried to scrape it off (I am away from my office on a biz trip), but will check it out when I get home. This might just be green algae. Is it common to have any algae on the back and side glass or are they supposed to remain crystal clear? I will post a photo in a day or two.
