Jacuzzi JLXL
planetary:
I also like the look of the LX series. If Jacuzzi offered an "XL 470", I'd've been done shopping a while ago. :)

I find myself hopping from one seat to the next for different massages. The two powerful jets in the footwell are my personal favs.
My one complaint... The jets, when on the high setting, sometimes spin themselves closed on their own. Not cool....
Plus...
Whats the difference between pH and alkalinity... I am a high school chemistry teacher and that doesnt seem to make much sense. An alkaline solution is one with a high pH...

I wondered the same thing about pH and total alkalinity. My understanding of total alkalinity (in hot tub land) is that it is a measure of the buffering capacity of your water. You need to keep the TA high enough to prevent big swings in pH but not so high that the pH climbs on its own. TA increaser is basically sodium bicarbonate. A person called "chemgeek" might come along and give you a better answer than what I did though. Good luck.

some good recommended numbers are as follows: pH 7.2 - 7.8, Calcium Hardness 100-150ppm, Alk. 80-100ppm, and of course you always want at least .5ppm chlorine present in the water at all times.
and yes Alk. is a buffer for pH so balancing Alk. properly first is the key to keeping your pH from "drifting" all the time. This is why at startup you should be ACCURATELY testing your water, and no test strips are not accurate...the recommended "home use" kit is the Taylor K-2006 available on Amazon for around $60 or you could always drive your sample to a dealer to check as well
