Hello everyone, I’m new to the group. This is my 2nd year as a pool owner. I’m struggling to maintain healthy water levels. These are my readings:
instant salt 0 ppm
salt levels reads 3900 ppm
Cell type: T-Cell-15
Gallon: 19000 salt water pool
I struggle with 0 chlorine and 0 free chlorine. CYA was 0. I shocked it and a few hours later added CYA. My pool guy recommended 2 bags.
EVERY trip to the pool store is at least 250-300.00…I’m trying to get it right without being taken advantage of.
Any help would be greatly appreciated. Have an awesome day!

Hello everyone, I’m new to the group. This is my 2nd year as a pool owner. I’m struggling to maintain healthy water levels.
Hello Max, and welcome. Can you tell us a bit more about your pool? Are you the original owner or did you buy home with existing pool? I know it helped when I joined to put all my stats into my signature line so others could provide quicker (and more 'dialed in') support.

These are my readings:
instant salt 0 ppm
salt levels reads 3900 ppm
Not sure what this means, unless your SWCG was off (the T-15) and therefore wasn't reading 'instant salt.' Have you tested water using a Taylor drop test kit (like K2006 Salt) or did you get these readings from a pool store?

Have you ever used chlorination pucks? Seems incredibly odd that a >2 year-old pool would have 0 CYA.

I know a lot of members here will ask for you to conduct a self-test with K2006 Salt (or similar) kit, then post your full results here. Also, PoolMath app if fantastic and highly recommended for tracking results, calculating quantities to add, and figuring out what happens in various "should I add" scenarios.

Also, more details about pool's history and quipment will be great. We'll help get things sorted...
 
This is the basic information we need to know in diagnosing a problem:
  • Show the Chlorinator Diagnostic Screens
    • Reverse Polarity and recheck the readings.
    • Show the Diagnostic Screens in both Polarities.
  • What are the first seven characters of the cell and box serial numbers?
  • What is the actual salinity and how are you measuring it?
