I can't see my reply I guess because I'm new otherwise I'd edit last message.
I checked the Best guess chart and what I don't understand is the accuracy of this when using a SWCG and mineral cartridge.

Since I was told to get my CYA up to 80 but my chlorine levels need to be only .5 since I have the mineral cartridge. On our own we're getting them to between 1-2 but this chart tells us they need to be even higher.

I can't remove the mineral cartridge as there is nothing to cap it.

Appreciation once again.
