Python and Water Treatment

Just wondering: why would you need to dose Prime for the entire volume of the tank? There would be no chloramines in the tank to start. It would only be the amount introduced with the fresh tap water. Dosing for the entire tank would be over-dosing. You can do that safely with Prime, but it is more costly.
You have to dose for the entire volume of the tank because when you fill the tank the chlorine and chloramines from the tap mix into the existing aquarium water and contaminate it so you have to dose for the entire tank.

Hm.. so I guess this (using more water treatment) is the only draw back of using a Python. I think the benefit of the ease of water change will outweigh that, haha.

Do you have to let the water from the faucet running when Pythoning? What if the sink is higher than the fish tank?
 
The Python instructions say you use the force of the water from the tap create the suction to draw the water from the tank. If the tank water level is below the bottom of the sink, you will need to leave it running to draw the water out. If your sink is lower than the tank level, at the start and end of the WC, you can turn the tap off once the siphon is started, though the flow out won't be as great.

Many folks just use the Python hose to darin the water to a bathtub or out a nearby window or door so water is not wasted to get your water out of the tank, then just hook up to the tap for the refill.

Prime is pretty much the least expensive off the shelf conditioner you can buy.
 
I read somewhere that you're supposed to turn off your filter if you fill up the tank using a python because you don't want the tap water to get on your filter media (because the chlorine kills the bacteria). Does anyone else turn off the filter? I always figured the conditioner worked quickly enough that it wouldn't kill the bacteria.
 
Never turn my filters off.
 
I turn my filters off on some tanks. Some have HOBs and they just aren't strong enough to continue pulling the water up the tube once it gets past a certain level. Some tanks I drain down past the intake so I HAVE to turn them off. Some, I don't even bother turning them off.
And like Rbish said, I only hook up my python to fill. I run my hose out the front or back door to water my flowers or bushes. They LOVE fish poo water!
