CWSTNSKO,
Where did you find it online? It seems like an elegant simple solution worth a $150 try and easy to remove and install. I live in Mayland and our pool is not in a very sunny area so my cl does not dissipate as fast. I would like to see if I can use this with a very low CYA (max 20 ppm) - a compromise between the Linux controled and higher cya needs of manual bleach control.
