How thickly planted is your 10 gallon, how bright is the light, and is it full of fast growing stems? Do you dose Excel? Depending on your answers, it is entirely possible to dose the water column without CO2 and be fine. My current set up wouldn't handle that very well for long.
Kitty litter is a cheap and wonderful way of adding iron to the substrate, which really benefits my crypts and Buce's.
