Sure I tried getting a good photo but its hard. Looks worse in person, almost looks like nothing in the photo. I scrape it, water gets cloudy then algae re-appears on the glass within an hour. Phosphate at .03
Nitrates undetectable. Light schedule and PAR in photos. Any suggestions?
I had the same strange problem in my 20 gallon AIO (all in one). Even though the water was crystal clear I could still dust algae off the glass two or three times a day. (At least it was better than having algae on the rock.) But like you, I got a little fed up with it, so I bought a large Sea Hare. He pretty much gets to it now before I have the need to do it myself. LOL.
I had the same issue with my tank at the 5-6 month stage. Eventually my tank balanced out and this stage has now passed (currently at the 9 month mark)
