I set up my tank around the 2nd week of January. It's been planted ever since. About 3 weeks ago i increased my light output to about 2.1 WPG. I am not dosing ferts and am not running CO2 at this time.
I have typical plants suck as anacharis, amazon sword, java fern, banana lily, dwaft lilly, crypt wendii, bacopa and a melon sword. All the plants are growing well and healthy after about 3.5 months.
Only problem is a slight growth of what i beleive is algae on my tank walls, OLD plant growth and my driftwood. The gravel is relatively clean. The growth is brown in color, about 2mm in lenght and looks like a strand of hair. On my driftwood it grows so dense it looks like a fuzz swaying in the current. It also grows back fast. If i clean my tank walls it will appear in a few days and start to grow again.
FOr algae control i have 5 ottos and about 50 snails (MTS, small ramshorn and pond) and they don't seem to make a dent in it at all. The ottos always seem full and happy.
I run my lights for about 12 hours a day. Lately since the growth has taken off i've cut back to 8-9 every day
Like i said, the plants are growing well and the algae on the driftwood actually looks good right now and the tank walls are not that hard to clean. It's just he growth on older plant leaves that bothers me.
Anyway to properly identify this type of algae and curte the problem? Someone mentioned to me it might be diatoms.
The growth spurt seemed to have started around the time i upped my light output from 0.5WPG to 2.1WPG. I was running CO2 before but stopped at the same time i upped my light output since i was told i didn't really need it.
