A friend of mine has a in ground pool. Its roughly 27ish feet long, 11.5" wide and starts at about 3' deep and goes to 6' so above a average of 4.5' feet. Based off my calculations im estimating it to be around 11K gallons. He said the SWG worked good as far as he knows for about 6 months and then stopped working, im not sure how long it hasn't been working. The SWG he has is a Hayward Aqua Trol. So while I was over there yesterday I noticed a few things that stood out. The first thing is that the control panel says "Above Ground Pool Automation", not sure what this matters but its something that I notice. I don't know much about SWG so this morning while researching it, I found a second thing that stood out. According to this illustration in the Operation & Installation Manual I think he has his installed backwards. The wires coming out of his unit is on the inlet side of the SWG not the outlet as per the illustration. Assuming after if I flip it around and it starts working leads me to my next question. How does it work lol?
The instructions say to add salt, you add it directly to the pool by dumping it in and then brushing it around to speed up the dissolving process. Is putting it in the skimmer a option? So with that being said if your adding salt directly to the pool what does the SWG actually do? How does it control level?
The control panel looks similar to this
The instructions also say to target 60-80ppm CYA with 80ppm being best (TPFC says 70-80) and a target of 2700-3400ppm salt with 3200ppm being best (TFPC doesn't show a target salt) and FC target of 1.0-3.0ppm (TPC says with CYA @ 70 FC levels should be 3-5ppm. Im assuming that since TPFC doesn't list a actual Salt level that the Salt level isn't that important, what is important is that you maintain a FC level of 3-5 and whatever the Salt is with FC @ 3-5 is ok. This is only my assumption. Please correct me if im wrong.
Is adding bleach to the pool still needed?
With the desired output % knob being adjustable between 1-100 how do I know what output gets me what ppm?
As for the filter he has that's a Pentair CC100 Cartridge Filter. How often should you replace the filter? I ask because he says everything he starts the pool up after cleaning the filter it blows all kinds of white looking stuff into the pool making it a little cloudy. He mentioned it was salt, I said its probably calcium. I didn't have my TF100 with me in order to test it but will soon!!!
