Has anyone ever tested these theories? I would be interested to see someone setup a experiment. Take the dirtiest tank water you can find and bag it in a few different bags. Leave it for a couple days then try a different method for each. Open the bag up and test ammonia, temp, ph, and TDS which each method.
I can do this but I don't have a TDS meter, but I can do temp, ammonia, and ph and have a drip system I can use. Does it really matter to have fish in the bag, I don't want to stress any of my fish out if I can just use dirty tank water?
