Would adding a second fixture be asking for trouble?
If anyone remembers I've asked this in previous threads.

My tank is 44g, with a 15 watt 6700k light T8. I have 4 valls, 2 swords, a ton of crypt wendii, some java moss, java fern, and an anubias, as well as a dwarf lily and a red tiger lotus that is SLOWLY COMING BACK FROM THE GRAVE. :D (can't wait for it to get larger.)

Well anyways, I asked before and got some mixed answers. Byron said to wait and see how things grow and that it should be enough. A few people said 15 watts wouldn't even be enough to grow plants. Well, the latter was wrong... they are growing... slowly...

Anyways, last night, I was fishing out a otto that didn't make it in my fish tank (day after I bought it :() and I had moved my lid a bit inward toward the front of the tank so the light was shining near the front of the tank. I have to keep it in the back so it shines on the vallesneria at least a bit. But, anyways, I noticed how beautiful my fish actually were since often they are in the front top which is pretty dark.

Anyways, I kind of just wanted to test out adding another 15 Watt fixture to my tank and see how it does.

Would this be completely asking for trouble or do you think I could manage it?

Anything is possible. Just remember, when you double the light intensity (which this would be doing) it will upset the current balance and create a new "balance level" and issues can arise. Second issue is, the fish may well stay where they are in the dark because that is what they want.

Will it be too hard to keep balance between nitrogen and CO2 and the light?

Sometimes finding the "balance" is not easy. I tend to start at the lower end and work up until things seem balanced. This allows nature to do most of the work, we just provide the essentials (light, micro-nutrients). Your algae problem in the other thread is solely because things are not balanced.

Is this the same tank?

Thanks byron for the help. :) I don't think I'm going to do this as of now. Everything is doing fine it seems. I have less algae problems in there than my other tanks. This plant stuff is really hard!!! I have a huge algae explosion in my 10g tank. :( So much hair algae x.X seriouslyy it's all over the plants and idk what to do. I'll keep trying to solve that though....

Anyways back to the 44g I think I'm going to just keep the one bulb. The sword is growing, so is everything. I just thought another bulb might make everything grow even better but until I get my other tanks under control I don't think I will attempt that.
