PS233 for Salt?

[PoolDoc]

I bought the PS233 kit last fall for my brand new pool that was filled in January this year. The kit works great. I noticed the new PS234 kit will have a "salt - PPM" option. Will this be available for us PS233 users? Or do I really need it and just trust the 3200 PPM reading on my Aqualogic panel?

There are several questions here, that I'm sure others have, so I'll try to answer them.

+ Purchasing a PS234 does not mean you have to toss* the reagents in the PS233. The reagents themselves have not changed between the PS233 and the PS234; I've just changed labels and quantities. There's already a cross-over chart that lets you tell how to match up Taylor numbers with the new PS234 numbers.

* Exception: the DPD powder (Taylor: R-0870; PS234: CHL #1) should probably be replaced annually, regardless. But, if it's still light gray and powder -- you may have to shake it up -- it's probably OK.

+ I don't know how relable the electronic sensors supplies with various SWG's are -- but my experience with many different sensors makes me suspicious and untrusting. Also, I'm pretty sure that those sensors do not actually measure salt; rather they measure conductivity. Conductivity levels result from the combination of ALL conductive ions in the water, and not just from sodium chloride. As a result, unless a field tech uses a chloride test to initially calibrate the sensors to YOUR pool AFTER it's filled . . . it's likely that there may be significant errors. This is especially true out west where some areas have high levels of ions present in drinking water.

It will be interesting to see, after a number of people have PS234s kits, how dependable the SWG sensors really are.

+ Eventually, I'll probably offer a standalone salt kit. But not before we're caught up on everything. Judging from past experience, that's unlikely to happen before mid-July.


Hope this helps;
