What's your DIY Carbon Dioxide recipe?

[WhispTech]

Well this is my first time for plants.

I switched out the carbon filter pad with some black aquarium spongs and some filter floss and the water seems clearer and ths the carbon doesnt remove stuff my plants need.

There is a bio wheel putting air in so says teh manual lol and the fish seems fine.

I have different plants though.

I have an amazon sword which I thin is ok.

The cabomba seems to be thinning out and every once in awhie I see a piece of it floating around.

The java moss I think is ok but I need to watch it a bit more.

My concern though is the corck screw val. It leaves seem to be like going clear in spots and spreading.

The lighting seems fine and saw other tanks like mine setup with same lighting with p,lants that looked healthy.

What type (fluorescent, incandescent, halogen, etc...) and power/wattage light do you use? With a biowheel, CO2 would probably be a waste as all the surface agitation caused by the wheel will release the CO2 from the water. I'd also be concerned about pH swings in a small tank if CO2 were to be used. Others may have more experience on this, though. You may get some other opinions if you post this as a new thread in the plant section. As for carbon filter pads or activated carbon in the filter, I only other with that if I need to remove med's or something from the water. Cabomba is a very high light demanding plant for it to thrive. I'd suggest looking for some Limnophila sessiliflora to replace it. It looks quite similar, but a bit greener. It also does well in low-moderate lighting-to-moderate lighting. HTH
