Make sure I got this right...

Plus you get immediate results, which is usually important if you have something bad in your pool that is causing the need for shocking. Cal-hypo works too, just costs a little more and adds calcium. I have a SWG and keep a couple of bags on hand just in case.

Thats what I thought, it seems shocking is a little "over sold" and probably overdone by most--at least thats the general feeling I get. A friend of mine has a standard pool, and he says that the only time he shocks is when algae starts to form, and his pool always seems very well maintained/comfortable to swim in.

You really only need to shock when your combined chlorine is over .5ppm.

Thanks, nice pool, I checked out your pics.
