Automatic pH controllers

The problem with the pool industry is that it is light years behind in automation. I have probes that have needed no adjustment in over 4 years but i have tested quarterly. The controllers are limited. Find a good electrician, get a plc with a small touch screen, with a few visits to even a cheap site like you will be way ahead of the pool industry. I am into my system for less than $3k and i can see all the data from my house.

how about a low cost (<$1,000) full controller, sounds to good to be true?
Late 2007, I went out to buy one such system, and after seeing the prices I decided to take the challenge and here we're now trying to provide it's benefits to everyone else out there.

Putting the final touches to the product and it will be available soon for the like minded DIY's and service people.

I did, and for my comment I'd like you to specify which "several states" have outlawed CYA due to the accumulation of cyanide.

Are they arresting people for selling trichlor tablets now?

Of course, as you have figured out, that site has a bunch of baloney on it. CYA does NOT produce cyanide. The only reason it is banned in commercial/public pools in some states, such as New York, is that it reduces chlorine's effectiveness and apparently in that state they are unable to manage proper use of CYA (say, limiting it to 20 or 30 ppm in commercial/public pools) without an outright ban.
