Hey guys! It sure has been awhile.
I am doing my regular multiple 5 gallon bucket water change routine. I live in Texas, and it is summer, so the water is really hot (83*F out of the tap today). That is way too hot for most of my fish, and out of the prefered range for all, as they are all tropical. My room is cooler than the rest of the house, so I know after afew hours
the water will be about the right temperature.
Here is what I am wondering. I know ice that comes through our fridge has chlorine in it (maybe chlorimines and other stuff...who knows what else), so I wouldn't want that to melt in a 5 gallon bucket. The concentration could be enough to injure the fish, and I don't want to take any chances with that. However, I though maybe it would be effective to take a small plastic bag, fill it with ice, and then put that inside another small plastic bag and seal both bags really tightly. I know that the water can leak out of the first bag into the second if it is left in there long enough, so I am watching it. Maybe I can find some bags with a water-proof seal.
But does this sound practical? It certainly seems like a more effective temperature decreaser. It seems at this stage like there may be a risk if the bag is left unmonitered (so I can't recomend this yet), but other than that is there anything that would be an issue with the bag in the water? I am not flucuating temps with fish in it or anything like that, but still I am just making sure that I didn't miss anything.
Hopefully I can find a plastic bag type that will make this work. Please feel free to comment.
