We have just completed the wait time specified by pebble tec (4 Weeks) and as owner builders we don't have much customer service available to us. We are also still waiting patiently for our test kit. We have been able to maintain chlorine and Ph with tablets in a float and slowly decreasing acid additions. Should I wait for the kit to test my own water or use the local pool supply? What do I need test before we add the salt? I have estimated that we have between 18,000 and 20,000 gallons between the pool and spa. Any help/direction would be greatly appreciated.
