Aquarium Advice FINatic
ok so im making a diy co2 system, and i made a test batch of yeast and sugar to see if everything is working out good. so i left it for 3 hours and there was alot!!! of presure in the bottle, and lots of bubbles coming up to the surface, im just wondering if this is what is supposed to happen becuase when i looked up some videos on it, the other ones had foamy stuff on the surface and mine doesnt. so is mine working fine?
