Aquarium Advice FINatic
Well I don't have a python to do water changes because none of the sinks near my tank have a screw-on end on the faucet. I don't have dechlorinator either. When I do my water changes I fill up gallons of water and let them sit for a week or two before I do my PWCs. My question is how long does it take for chemicals like chlorine and chloramine to evaporate out? I've always thought it was a few days but i'm just curious.
