Overfeeding
had a horrible experience with hair algae just recently
+ 1 on overfeeding I know I was I also reduced my lights To 5 hrs from 10 on the mh and went from 12 to 7 on my pcs.....
i also found that without an auto top off my skimmer was way underperforming due to the fluctuating water level. as soon as I added the auto top off it leveled out and pulled way more I'm sure this was the icing on the cake.
Not an expert by any means.........Just 2 cents
