Always wanted to see a direct comparison of no co2 vs glutaraldehyde, I almost set up a few tanks to do the comparison myself. Cool stuff!

@fatturtleking Thanks. Doing some more in the future right now I'm currently working on diy and tablets, plan on doing a dennerle carbon product, seltzer water, and airstones as well in the future.
