Converting pool to salt water to use salt water generator instead of Cl Pump.
Chlorine prices continue to rise, and once installed this will make pool easier to maintain, no more buying and lugging around bottles of chlorine or bleach.
SWG Unit Hayward AQR15 AquaRite
SWG Unit Hayward AQR15 AquaRite
Choose to use the Hayward Goldline W3AQR15 AquaRite
I bought from Leslies, but lots of places have them
This is a 40,000 gal model for my 20,000 gal pool.
You should oversize so it doesn't have to work at max capacity, and you don't have to run your pump 24/7 for the SWG.
To determine the total output (lbs chlorine gas) per day check the amps while running and multiply by 0.18
Check LED
hold down the Diagnostic button (3-5 seconds) to reset the timer for 500hrs
Time
It reverses polarity every 3 hours, so run at multiples of 6 hours: 6, 12, 18 or 24

I ended up buying salt from Lowes for curbside pickup. But I had to load it into the car lol
Bought 10 bags, used 6 1/2 to get salt to 2800 ppm. I'm keeping salt on the low side and will see how that goes.
5/24: Start at 1200 ppm. Calculator says 300 lbs (7.5 bags) to get to 3000ppm.

40 pound bag = +239ppm
Added 7. bags , 1200 to 3000 = 260 per bag

2.78 ounces/ppm in volume
one cup = 25 ounces = 9 ppm per cup, round to 10 ppm per cup

Bought a bunch of normal 2" elbows @ $4.40 each
2" Spigot x Socket pvc elbow $8.70 each at hd
Shopping list
Unions from Lowes. Bought 4 of them, two for installing swg and 2 to make a bypass when I want to remove the swg for maintenance. Cheap enough to buy 4 of them
I needed another hayward union because I messed up, bought a 2 pack
Layout and dimensions
Normal elbow. 1.5" from end to stop inside, so need 3" for two elbows
two normal elbows are 8.5" edge to edge when as close as possible so would need 11.5" of pipe to install with normal elbows
Kit requires a 6.5" gap so it saves 2". By using a spigot x socket elbow on top.
I have 11.5" max to work with between two elbows from heater to return entrance. So theoretically could do with normal elbows but its leave no exposed pipe so I don't like that, but came up with different layout with help from trouble free pool forum.
Dimensions of parts
15 3/4" SWG + hayward unions on ends
3 3/4 Flow sensor pipe.
15 3/4" Flow sensor + 12" straight pipe that flow sensor requires
Equipment picture before starting
More dimensions
3 3/4" Union
2.5 " spigot x socket elbow to turn far edge
Cut pipe between heater and filter to add flow sensor
Flow sensor installed, no leaks after tightening union

I used 120VAC for power (vs 240V).
Had to knock out a piece on the bottom of the controller to make a hole, then connected a 1/2 watertight straight conduit.
I have some 3 x 12 gauge wire that I used
This stuff from Lowes would work
I also had a heavy duty 3 prong plug. You can also find them easily at HD or Lowes.
I will plug it into my smart switch that I had been using for the Stenner pump that I don't need now. This will let me control when to power on the SWG.
