Having a hard time getting and maintaining CH. Adding calcium chloride but it continues to drop. Is this typical for in ground plaster pool in Central Florida?
 
The only way to get CH out of a pool is to replace water.

It may be that you have a leak...try the bucket test.

Do you have an autofill?
 
The WaterGuru tests indicate everything is in the Normal range (FC, pH, CH, TA, CYA) but PoolMath SCI is on the low side at -.61

Unfortunately it doesn't indicate what is out of wack or how to fix it.
