Can I generally rely on the readings I get from my Hayward AQR15 for salt PPM or ought I really do a test? If so, are Aquachek strips good enough or do I really need to buy a K-1766 or something similar?
Additionally it seems that my salt is dropping off rather quickly. Evaporation should not affect a change, right? Mine was high (up to 4400 according to my SWG) but then I lost approx. 20% of the water (over days, I was refilling) due to a leak which dropped it to 3100-3200. I added a bag and it read at 3300-3400 for a few days but then dropped back to 3200, any thoughts? There are no apparent leaks now.
