Csi And Rotomold Spa

[trigear]

I posted yesterday and for some reason it is gone.

Is there any reason to worry with csi on a rotomolded spa?

Thanks

I don't think so. The material isn't plaster and it doesn't have tile so no grout. Basically, you only need to worry about maintaining a near-zero CSI when there is calcium carbonate material to protect. Of course, too high a CSI is a problem regardless since it can lead to scaling, especially in the heater.
