I have one I connected to my Spa and modded to run 8 mins a day, anything more and it was WAY too much chlorine! I plan to move it to my pool slab along with a second one I got. Bought both on clearence from Walmart at the end of last season for a steal. (199 to 150 on red sticker clearance, then was in 50% off isle, then they went to 75% off everything with a red clearance tag for home and garden) So I paid around $38Originally Posted by NWMNMom
I have a 20k gal. pool, I plan to pumb them in parallel. Why not serial? Well, its like batterys, You may connect them in serial to increase output potential (voltage) but at the same volume (GPM or amps) as comarped to a single unit. You may connect them in parallel to increase volume (Amp hours or GPM) but at the same voltage as one unit would be.....hmm this is getting tricky. howa bout this:
Serial= higher PSI/voltage
parallel= higher GPM/amps
The real world reason is simpler. Two units in parallel will divide the GPM between the two units soo the resistance (added head loss) isn't as bad going thru 2 cells as aposed to just one. And serial would be undesirable because the electrical process already happened in the first cell, now how effective could a second cell in serial be? It would be washed with fresh chlorine from cell 1 probaly not great. (thius is why suplemental chlorine dispensors are added AFTER SWG's) Also there would not be as much salt water available to convert as cell one already converted some already.
I welcome anyones input to this subject
