View Full Version : Dechlorinating with a Python
The literature that comes with a Python says it's use eliminates also having to use a dechlorinator, thanks to sufficient aeration. I found this notion repeated at the skeptical aquarist, so...
Does anyone here use a python here without a dechlorinator?
Does anyone use a diminished dose of dechlorinator with their Python?
Other thoughts?
Thanks

I still use a dechlorinator to be on the safe side. I add it while the water is beeing put back in.

I wouldn't add more than 10% to a tank without dechlorinating.
Just out of curiosity, how could aeration get rid of chlorine and chloramines? I've never heard of that.

The exposure to the air when it is coming out of the tube is supposed to dissapate (did I spell that right?) the chlorine, but the chloramines will still be in your water. I wouldn't chance it unless you know this stuff is not in your water supply. It's not worth the few cents you would save to chance losing your fish. Just add the dechlor just before or during the time you refill your tank.
I can now attest to the fact that you must put de-clorinator in. I use the Python for my water changes. Saturday I changed the water as usual, put in the water conditioner, I thought everything was just like I usually do. I cleaned-up, put everything away, looked at my tank - there were all my fish at the top of the water gasping for air. It took a few minutes to sink in that I must not have put in enough, so...I added some more. Still at top, put in some more...finally everyone looks like they are getting back to normal except my cardinal tetras. Unfortunately I lost all the tetras! I thought everything was like I usually do, but apparently I lost count of what I was putting in. BAD MISTAKE!
I've had my tank for almost a year now and thought I was doing so good. Hadn't made any mistakes that had cost me any fish! I can't say that now! Really makes you feel bad!

Like Gunnie said, the aeration will eliminate the Cl2, but not the chloramines. That is, after all, why chloramines are used. Cl2 is not very soluble in water and even left sitting will be pretty much all gone after a day (which is why a brita filtered pitcher in your fridge for chlorine elimination is a bit of a waste). Chloramine on the other hand does not evaporate.
