Thanks Len. I do have one otto in my tank and he's doing very well with the green algae. I couldn't believe that he alone could clean my gravel the way he has. I'm definitely keeping him. But, he won't touch the other algae in my tank. I know that these fish aren't the answer to my problem, but I would at least like some control over it.
I know I have a problem with my water, I can't believe that I have 0 nitrates in my tank. I'll take care of the problem as soon as I get my phosphate kit. I do feed very lightly and every other day. I have seen the fish eat some of the algae (the proof is in the poop, he, he.) They are always pecking at my driftwood.
Right now, I have at least 75% percent of the tank covered with healthy tall plants (thanks to the DIY CO2 3 litter bottle. I use it with the Hagen latter). My plants are: Sunset Hygro, Asian Ambulia, Rotala Indica, Bacopa, L. Repens and one Java Fern. In the last week I have pruned my plants at least 5 times.

It looks like a jungle in there.
The algae started when I added the 20w No FL light. I only added the extra light because there were some shaded areas in my tank. The wpg rule is somewhat confusing to me because some have said that long tanks require more light to cover shaded areas. I did that and now..Boom...I have algae. According to the wpg rule, I have 3.75 wpg in my tank (or do I?).
So my question is, did I make a good move getting an extra light for the shaded areas, or did I mess up my tank with the extra light? I figured getting a No FL (not as strong as CFL) wouldn't be a big deal , but I guess it is. Can you give me an opinion on this? Maybe I shouldn't use it anymore, what do you think?
Thanks for your help.
