That would be 375ppm.
How high should it be allowed to go before thinking about replacing some water?
That would be 375ppm.
So what happens if it goes much above that level, or is it just an issue of being harder to manage CSI?I manage my CSI until my CH reaches 800 to 1000 ppm and then do a water exchange.
I noticed Pure Water Industries that provides on site filtration is in my area. Do they charge by the gallon?As the CH gets higher than that, CSI is tough to keep in range as you cannot manage your TA and pH low enough. First sign for me is the SWCG starts releasing calcium scale flakes into the pool. Also the water line tile scale buildup increases. Beyond that, you can get full on scale build up on your pool shell.
If your water use / cost is a big deal in your area, I suspect they have Reverse Osmosis services that come to the house and remove the TDS from the water. You sitll use about 25% new water volume.
That’s about three times the cost of replacing all my water.I imagine it is a flat set up charge and then by pool size. Most numbers that have been posted here are +/- $1000.
That's pretty much it. Their business model invokes the 'green' view of not 'wasting' water. Kind of odd, the only way to 'waste' water is to pump it into deep well disposal systems.That’s about three times the cost of replacing all my water.
Thanks. I’ll just keep an eye on the CH and maintain -0.3< CSI <0That's pretty much it. Their business model invokes the 'green' view of not 'wasting' water. Kind of odd, the only way to 'waste' water is to pump it into deep well disposal systems.
