richardhmc;662459; said:I see.. Hmm, So if I add an airstone into my tank, this should de-chlorinate the water?
Then what is the best way to add the water into the tank? and take it out?
Maybe then 15 percent everyday? little by little?
Nope! Never add tap water directly to your tank. There are people here that do all the time, but resist the urge. They are not the ones who have to live in the fish tank.
If you age the water before adding it to the tank, an airstone will mix up the water bringing the chlorine to the surface so it can bleed off. Chlorine evaporates faster than water, that is why this technique works.
If you can not get permission for buckets of water in the house, just use dechlor. Mix it in your fill bucket and let it set for about thirty seconds. It is fast acting but again, resist the urge to do the mixing in your tank.
Taking the water out using the Python is the easiest. Btw, you don't need to keep the faucet going during the whole process. I turn mine on for a few seconds just to get the syphon going. I also drain to my shower rather than the sink. The lower the end of the hose, the more powerful the syphon.
To refill the tanks, I have 1.25g, 5g, and 20g containers. The 1.25 is for small tanks and top offs. The 5g requires some man-handling and the 20g gets a sump pump to do the dirty work.
