Never tried . I usually use my 3ft glass cleaner stick, it comes off pretty easy though. I have a Vortech mp40 powerhead so can’t even try to blow it off if that is what you meant.
Not sure to be honest I guess it could be I just feel I clean both the front and back and the same times but maybe not. Maybe I do clean the front more than I realize and maybe it’s that. So if I did t clean the front as often it would get that dark and thick over time?
Before determining anything. please furnish clear pics using white light intensity only. Probably film algae but anything is just a guess. This is what we see:Can anyone identify this, sorry for the pic it’s the best I can do. It’s in the back glass only. My front glass gets algae also but this stuff is thick and looks very dark green or black. It’s never this color or this thick on my front glass. My phosphates are .05, did two test, nitrates were 12.7. I use the Hanna checkers. Thanks
I'm not 100% positive, but I would think so. I try to scrape my front and side glass every day. If I don't, it gets pretty dirty by day 3 or so. Now imagine not doing it for weeks, or months. I scrape my back glass every month or so and by the time I do scrape it, it looks really bad too.
Makes sense yeah, I cleaned both today so I’ll leave it and see until I’m ready to clean the front, the other thing is the blue background on the back that probably doesn’t show the light algae like the front glass shows after a few days
I notice buildup starting within a day of scraping the glass. If I don't scrape it, it looks pretty bad after 3 or so days. I only scrape the back glass maybe every month or so and by the time I do, it's pretty caked on.
