When you refill the water that you took out for a water change, do you treat it with anything? I went to the python website who sell the python no spill cleaner and it says, because the water traveling through the long tube from your faucet is being aerated that it takes much of the chlorine out and you don't need to treat it. I was wondering if this is truely safe.
 
while aeration will remove chlorine, most water supplies are now adding chloramines precisely because they are more stable. to remove those, you need to use a tap water conditioner that specifically says it removes chloramines.

Python users on this forum, myself included, just add enough conditioner into the aquarium to treat the entire volume, not just what you are adding back in. so far, no one has had any ill effects of doing it this way. My fish, for one, are happier and healthier than ever, now that they're getting more frequent and larger water changes :)

Some folks prefer to still treat water first in a bucket. I understand that, as I thought it was weird to let a chemical reaction happen all around my fish. But the whole point of the Python is to eliminate the need for buckets. Whatever you feel comfortable with and works for you, is just fine.

But I am never going back to the bucket method! I would always spill at least one gallon each time I tried to lug that thing around the house.

Well doesn't water aged for 24 hours take out all the chlorine?

lol... but i still dont get how the python works... how do you measure the temperature so it matches the aquarium?

I would like to know that too, or if you even have to mess with it. I'm thinking if you change 20 percent of the water that the cold water from faucet shouldn't drop the entire temp of the tank's water that significantly to cause shock. And that later it will quickly come back up to normal.
 
i have to let the tap run for minutes, sometimes, before the temperature gets the same as the tank (measure both with a thermometer), so it wastes a lot of money during that time. then you switch it from "Drain" to "Fill" mode.

yes, aging will get rid of chlorine after some time, but it's chlorAMINEs that i was talking about. those pretty much never break down, or if they do it would take years and years of aging. that's why you need a special tap water conditioner, not just a dechlorinator.
 
Ok, how can you tell if your tap water has chloramine?
 
you can call your local water supply, or they often have websites with that info, too. it's public domain info, so they have to have it available to you somewhere.
