Thanks guys,
From what you are saying I'll stay with tap water rather than using
rainwater.
We have choramine in out water supply so I'll use choramine remover and
let the water sit for 48 hrs before using as you recommended.

I have a very noisy powerhead that I was going to throw out but it may
be good for pre-treating the tap water before I add it to the aquarium.
I can do this in the outside shed so the noise won't bother me.

BTW are there some brands or models of small inside powerfilters that
are very quiet?

I use mostly aqua clear filters indoors, they are usually quiet. The
power heads I have are quiet when I maintain them properly, keep the
sponge from collapsing, purge them of air when they get air into them.

My filters get noisy when the center shaft of the motor wears thinner.
Replacing the shaft quiets them again.
