I have been testing my salt pool water weekly with no problems, after shocking (boost) it last week the nano- machine said to add salt, which I did, the next day, the light on my salt machine was blinking warning add salt, I did, tested the water and the stabilizer was low and the free chlorine was low (according to the test strip) went to the pool dealer and they gave me stabilizer, told me to pour half the bottle of crystals into the basket and test the water in 3 days, if still low, add more. I did this, stabilizer was still low after 3 days and testing, so I added a little more, but the salt cell machine was only asking for 20 lbs of salt so I guessed something is working correctly, tested the water this morning, 3 days after adding stabilizer the second time, and it was still low on stabilizer. The machine is asking for 7 pounds of salt now.
The water is clear, no algae, but I am concerned about adding too much stabilizer? The test strip reads that the stabilizer is between 50-100 and the pool dealer told me to bring it up to 100 (on the test strip) is this why the free chlorine is low as well?
