Here is a picture of an algae that has been growing in my tank for a while now. It doesn't pose a problem with any fast growing plants because I prune the effected leaves, but it does make problems on the slow growers like the Java fern, crypts and on the driftwood. It grows mostly, but not always on the leaf edges. I've read a lot of descriptions of algae but I'm not sure exactly which one this is. It has a gray color and it sometimes grows over 1/2 inch long. My shrimp seem to trim some of it down but they don't keep up with it. The ottos and SAEs don't seem to touch it.

Any idea which algae it is and how to keep it under control?

29 gallon
20 ppm Co2
5-10 ppm nitrate (KNO3)
.2-.5 ppm phosphate (KH2PO4)
2.5 ml flourish Iron (daily)
3 ml TMG (daily)
2X55w PCs
Water change once a week

I was thinking that it could be hair algae but it seems more meaty than the hair algae that I previously had in the tank. I'll try increasing the Flourish to 4 ml per day. Does that sound like too much for 29 gallon 110 watt? I'll post the results after a few weeks.
Thanks for the help.
