W Bell,

Check the thread below of my experience with SWCs or SWGs.

Keep the pH at 7.2 - 7.6 for best Cl production. Use plenty of acid for this.

You will be brushing every day to remove the calcium hardness from the pool bottom and walls as the plaster cures. Vacuum to waste, to keep between 200-400 ppm CH, and refill with softened water if you can. Once the Cl starts to steady out from 3 - 5 ppm, the curing should be nearly over. Do not scrimp on this part of the process.

Not knowing your SWC model, I would suggest adding salt, and maintaining 3000 - 3500 ppm level, and replenish after vacuuming to waste. The CYA should be about 40 - 60 ppm, and that too will have to be replaced.

Your running time is more than adequate, and you may be able to cut back, as you get to know your system.

Hope this helps, and post some figures when you have worked out the PS234 kit.

Have a great pool party.
