What water conditioner do you use?

Prime is always the first choice.

Amquel plus would be next.
 
I always used Prime, before I moved up North and now have well water. It is a reputable product, and it not only removes chlorine, but chloramine as well, which is another additive in some municipal water supplies.
 
Prime.

I used to use Stress Coat, but it tends to foam up if you add too much at once (treating the whole tank for instance). Plus, Prime is far more economical (2 drops per gallon) and it neutralizes more things than Stress Coat did.

Prime is one of the best things I've learned off of this forum, and I've learned lots here :)
