Thanks for the information, had not thought of using the CYA to counteract any corrossive effects. Will try it out... Tks

Thanks for the information! Great thread with SWCG. I am looking at putting a similar system on a Sundance Capri...we have moved and no longer have access to my HS Grandee (1996 model) that I placed a EcoSpa (Australian model) SWG on in the circulation loop. Worked well, had flow control to ensure water was circulation before activating electrodes, salt indicator to tell whether enough in to generate chlorine, indicators for high, low and activation, self cleaning. So in essence, it worked very well once you understand what it was doing and how to balance the water. I did experience some corrosion at the water heater (welded bolts are low grade stainless), but after replacing one heater coil and sealing unit tightly, no ill effects. After a decade of use, I figured I was due. The thought of using zinc to counteract the galvanic effects crossed my mind, but have not seen a need for them. The upfront cost is high, but the satisfaction from using, not adding chemicals (my wife does not monitor), soft water and fact that I can walk away for a few days without monitoring are enough for me to do again... Again, thanks for the information!

Anyone out there with any experience using a Salt Chlorine generator on their spa? Like the pool set-up and soft water, but will this work on a spa also? I understand the effects of SW on dissimilar metals, corrosive and galvanic effects that may affect heaters, pumps, and PVC piping used in spas. Read a lot of manufacturer's claims, but what I am looking for is actually use from the informed consumer. Other than initial cost and possible lifecycle costs, Will this system work...and what should I expect? Have scoured the spa forum, searched and not found a lot of feedback on the subject. Did I miss something? Thanks for any opinions and input!
