Something's out of balance. Please post your stats. Also, are you dosing
with trace elements?

I am still fighting algae. What I have now is dark reddish brown but not
"powdery" like diatoms. It is definitely more like green algae in texture.
When I trim the plants, the algae looks black once out of the water.

I have a 29 gallon tank with a 55w CF, fluorite substrate, and Nutrafin
CO2
kit. Plants include Nana, Amazon Swords, Onion plants, Java Fern, Pond
Penny, Anacharis, and Rotala indica. After two hours of light they all
perl
like crazy. There is a shower of small air bubbles floating up to the
surface.

I have been cutting back on the light and am now down to about 10 hours.
Will it count toward a light reduction target if I start turning off the
light in the middle of the day? Will it inhibit growth or damage the
plants?

I am hoping that by slowly cutting back on light I can eventually get the
algae under control. On the other hand, I want to see the tank while I am
at
home. Any advice?
