We moved into a new house with a salt water pool and are just getting started on understanding how to maintain it. Our ECO-matic was getting the two red lights on so we bought a TF-100 test kit and salt strips. Here are some results:
Salt: 1000 ppm
CH: 300 ppm
We had hired a pool guy to "take care" of the pool at first but he seemed a little clueless, and it didn't help that the ECO-matic was getting the red lights and he hadn't even brought it up to us. It appears that he never even tested the salt level because it is way below the approximate 4500 ppm that ECO-matic suggests. We suspect that the previous owner never changed the water in the eight years since the house was built. Since our CH levels seem to be normal, is there any need to drain the pool and change the water? I bought 240 lbs of pool salt today and thought I would check whether is was necessary to change the water before throwing the salt in. Any thoughts are appreciated.
