... they'll charge ya something like eight to twelve bux for a cheapie test kit that comes with a bottle of reagent and a little thingy to measure your water in. You fill it to the recommended level, and then put two or three drops of reagent in, and then check the colour against a colour chart (usually on the label). As long as you keep the ingoing ph at what it is supposed to be, everything should be fine.

stra8 and BL are of course right aaaaawwwwn, as usual
