My riccia has become choked with hair algae this week- is there anything I can do to remove it? Excel isn't an option, as last time I used that in my tank any riccia that came into contact with it turned white.

I believe the hair algae is forming from a combination of old flourish gravel and my fert dosing. Everything will be fine in my tank until about one week after I do a water change, then hair algae will break out. Doesn't touch my stem plants...it just grows thickly on any exposed gravel, and the riccia since I added it.

Tank is 10 gallons, 40watt pc lighting, diy yeast co2, dosed daily with the Pfertz line. Ph 7.0, ammonia 0, nitrite 0, nitrate 10

Try amano shrimp. They eat hair algae.

Well, I've already got a virtual legion of shrimp in there now..plus some -very- fat otos. Aren't making a dent in the riccia (but they keep my stem plants looking great)
