Thanks for the nice comments.
I put a female guppy in the trap, she was in my 20 gallon planted tank but for reasons to long to explain I put her in this one just temporarily.
As for Co2, I go the poor mans route and use hagens Co2 "natrual plant system" and yes, you can get this and other ones similar in pet stores.
About liquid ferts, I used solid and liquid.
I have plant sticks in several root systems on various plants and I add the recomended amounts (actually, about 1/2 to 2/3 of the recomended dosage) of seachems "Floursih comprehensive supplement", Plant gro iron enriched, Florapride, and the occasional dose of blackwater extract, which is peatmoss and other ferts in a liquid form.
I also use flourite substrate, a clay based substrate for the planted tank.
Peat moss fiber in my filter, and the mopani wood also helps with water quality and plant growth.
