I have a new to me but old fiberglass pool. The CH was around 60-80 when I took it on and I have raised it to about 300 over the last couple months. I do have some stone around the pool and the spa overflow is all limestone/sand stone.
The strange thing is I live in San Antonio where the water is traditionally super hard - a friend has a CH of 700-800 (we get our water from an aquifer). So I've been fighting some leaks and having to refill from the hose. My first thought was the hose was sent through the water softener. I have another home a few miles away and test the hose water at CH 120. I verified my Taylor 2006 tests with a couple pool stores.
Anybody else in the North Central San Antonio area that can test their current hose water CH? The reason I ask is the city has recently started using water piped from 150 miles away and I'm wondering if it's just naturally low in CH.
Should I be trying to get my CH to 350 anyway? The pool is 15 years old or so and there is a lot of scaling - I'm not sure if any attention was ever paid to CH. My thought is that is was very high for the majority of the time as San Antonio has traditionally high CH water and has gone very low in the last couple years due to the possible water supply change. I know CH doesn't just go away, but I think this pool has been losing over an inch a day for a very long time. (under control now). I'm beginning the calcium cleanup but thought it wise to get to the optimum CH.
