I just moved into a house with salt water pool. The volume is about 17,000 G. SWG pump is more then enough for the capacity of pool. I had the pool drained and cleaned a month back. The chlorine level of the water was at 0ppm and the pool superstore recommended to use quick shock chlorine tabs. I used it the level was at 3ppm. 5 days later it was again at 0.1ppm. they pool superstore recommended to quick shock it, which I did. They said it is normal to supershock with chlorine tabs once a week. The pump is set at 70% chlorine production. I was wondering if it is normal to supershock with chlorine every week? Is the pump producing any chlorine at all?
The test results for the pool are:
Free chlorine 0.1ppm
combined chlorine 0.5
free chlorine 0.4
ph 8.2 (which i lower with muriatic acid)
Cyanuric acid 15ppm (still dissolving)
Any help would be greately appreciated
