Science Question for the Chemically Challanged

My fishtank is getting too warm, because the outside temp in the house is too darn hot. I've been doing water changes in my aquarium, taking out the warm and putting in cool from the tap after treating it to remove the tap water chemicals.

Here's my question.

If I freeze tap water in an ice cube tray, will that freeze away the chlorine and the assorted chemicals that are in my tap water? What would happen if I froze the treated tap water? Would the dechlor stuff still work? :?

I'm stumped on this one, so any ideas would sure help!!!

My answer would be no, I close my swimming pool in the fall and I put about 5 gallons of chlorine in it. It freezes over the winter and in the spring I open the pool and the cholrine is still in it. I think the sunlight is the biggest killer of cholrine. Not a scientific opinion, just drawing on my experience.

Wow, I would have thought the chlorine would have evaporated away long before that! :shock:

I cover the pool in the winter. One year I did not and the pool turned green by March. It was not even warm yet. I was told the sunlight killed the cholrine and I have always covered it since. It has never turned green again.

Nope. The chlorine might evaporate out before the water freezes (or after it thaws), but the freezing itself won't get rid of it.

Dunno what kinda treatment you do. But once you got the chlorine out, freezing the water won't put it back. Or you could de-chlorinate the water after melting it.

So it sounds like best way would be to declor the water and then make ice cubes with the treated water.

Thanks guys!!!

DA's right.....chlorine hasta evaporate before freezing...gotta let it air out for a few hours...we hadda do that with city water before we put it in our tanks too...then you can freeze it :headbang:

don't keep the tank near a window either...that'sbadmkaaay :-D

The big tank is away from any sunlight. The Betta's bowl, though, gets filtered light during the morning.

No algae yet. :D

cool Julie! :headbang:

if you can, buy some algae eaters too...they do such a good job, you gotta buy algae to FEED 'em after a while...

Sigette keeps fish too, so she's pretty savvy about that kinda stuff....

Hot water does not stay chlorinated for long. If you run your tap til it's hot and then put some of the hot water in a container and let it sit overnight, and then freeze it, all should be well.
