I am looking for recommendations on a SWG for an above ground pool. I have a 28' round, 52" inch Doughboy Desert Spring (steel construction with resin top rails) and want to convert to a SWG. We installed the pool last year and the main issues were high alkalinity which I lowered with muratic acid and aeration and high CYA (due to use of chlorine pucks in automatic chlorinator). Too lower CYA I had to partially drain and refill, then had to lower alkalinity again because of the refill. Switched to bleach as chlorine source after that.
Doughboy discourages the use of SWGs and promotes a dual Frog system that they sell exclusively. I believe Doughboy voids your warranty if a SWG is used. Nonetheless, I am looking for other people's experiences/recommendations on a SWG for AGP. I would think a system that is able to produce a sufficient amount of chlorine with a lower salt input would be desirable in terms of lowering the potential for corrosion.
Any thoughts on the Autopilot AG series? I considered the AquaTrol but worry as my pool size would be at the top end of the 18,000 gallons the cell is rated for, possibly I should be looking at the AquaRite.
Would I be better off with a larger cell that did not have to run as frequently to produce the desired chlorine since my natural fill water is high in alkalinity? Does the SWG always run when the pump does? I know I didn't have to, but I ran my pump last year 24/7 just to keep the water moving.
Sorry for all the questions, but thanks in advance for a helping a newb!
