Ok thanks for the reply. Fill water CH is 300. More650 is workable (I am just north of 800 now) - maybe even until a full drain come early spring. Keep your water balanced and keep you CSI in the 0.00 to -0.30 range to reduce the chance of scale buildup.
Remember, any water you drain will be replaced by fill water with a CH in the ~225 ppm range so a large replacement will be required to make any appreciable change.
300What is the hardness of your fill water? You may not be any better off if you do.
So do you do a full drain at some point?200-300 is our "normal" tap water hardness - it varies a bit throughout the year.
With our evaporation rates in the "Valley of the Sun", chances are your entire pool volume evaporates every year (maybe more frequently). If your fill water is 300, in a year or less it will be 600. You can usually manage it up to about 1000 ppm CH.
Oh cool, I may have to look into that at some point. ?Yes, a total drain and fill. My plan this fall is to plumb my autofill into my water softener so I can add make up water that has low/no CH. Fill from empty from the hard water tap, use soft water to replace water lost to evaporation.
Yeah, I think I’ll be ok through this swim season at least. Thanks for your advice!Yeah, you should be agle to easily manage thru summer and maybe even knto early spring. Just continue to test and keep your CSI in the 0.00 to -0.30 range. As the CH continues to climb, you will need to lower pH to keep CSI in that range. But keep pH in the 7's.
Always best to drain/refill when the weather is cooler. As you know, we are into our 105+ temps. And not going to cool down much until some time in October.
