Is it a bad thing.. ?
When I scrape my tank walls, there is usually always that green film that's caked onto the glass. When I scrape it, it all just goes floating away in the tank... is this bad? I never really thought anything of it because it's just the film, but then when you scrape it off you see it all float around in your water column. I use an AC500 with sponge so I am sure some of it get's sucked up in there. But is it bad to have that free floating film algae go all over the tank? If so, I need to figure out how to siphon while scraping.
