The tap water itself, in some places is quite nice for
these purposes.  Although I don't use a top-off-for-months
method, the water here would work well for that purpose. It
comes out of the tap with very little of anything in it but
chlorine (no chloramines), which is easily taken care of. 
Yet a little bit can add up if you are adding back 1 or 2
gallons a week per 15 gallons of tank.

I doubt that it's a method easily adapted to open top tanks
;-) .

Amen to that.  You have to watch your fish and plants.

Folks measure the water, the chemical ferts, traces,
carbonates but just toss in fish food by eyeball estimate. 
Newbies could do worse than to measure the food they add.
It's not hard to do, and it's a helpful way to avoid over
feeding.  Not a cure, but a help.  With the high protein
content of prepared foods, fish need much less than many of
us supposed when we started out.

Uh huh. Anyone that does tens upon tens of gallons of water
change every week has asked, even if only silently to
herself or himself, "Can't I avoid all this drain and

Sure you can avoid a lot of it, but you have to follow
through on your method; you can't do half one method and
half another and then expect things to come out alright.

Well, I can't take credit for that -- so many others have
done it so well. I think it's good for other methods to be
floated on APD.  Every now and then we need a change from
all the Change talk, or things can get a wee bit stagnant.

Good luck, good fun,
