I was thinking about getting a python system for water changes. However, I was wondering about how you add new water to the aquarium if it has not been declorinated yet? Or do you just add declorinator after.
you add it later or if water changes aren't too big i dont even worry about it if i change a lot i get an empty 1 gallon jug and and put the declor in there and fill it up then add the solution as i refill.
First, make sure the water temperature is right, then, as the water is going into the tank, add a few drops of dechlorinator to it. Thats about it, very easy.
I use a python to do water changes in six tanks. After I've vacuumed each tank's gravel and removed about 25% of the water, I then go around and add my dechlor to each tank, then refill each tank. Never had a problem doing it that way.
As a side note, if you use Stress Coat you can add just enough to treat the amount of water you're replacing. If you use Seachem's Prime, you're supposed to add enough to treat the entire volume of the tank.
I have had my python for awhile now, and it's worth every penny. I have a slight disability with my left leg, and the python sure helps out in the water changing department. I always just add my dechlor right before refilling the tank, and have had no problem. I clean 1 100 gal., 1 55 gal., 1 29 gal., & 1 20 gal. long tank is less than an hour! I highly recommend the python.
