Thanks Waterbear for enlightening me. That link was both informative and a bit amusing.
If I read you right this unit is a combined SWG and ionizer?? Too bad I couldn't dissable the ionizer and just let the SWG function normally.
You see I found a good deal on this Duoclear25 $70 bucks for the control panel and leads to cartridge top, but no cartridges. so I thought I could get a SWG for under $200 bucks. Which would take care of my brushing the algae from my pool 3x per week. Maybe I'm doing something wrong. I had high calcium levels last year. So I drained 2\3 of my pool. But the problem still persists. Looks like I'll have to peruse this forum and/or post in another catagory.
thanks
Craig
