I tested the water again - the CYA is 130 and Leslie pool insists it is the sole reason for my problem - the other place that I use, equally insists that CYA of 130 is not the main problem but the total dissolved solids. Not sure what to do and whom to believe!

I have a 12000 gallon in ground pool in Northern California. I drained the water about two years ago. The TDS is now close to 4000 and the pool store is telling me that is the reason it is not holding chlorine. I use liquid chlorine as needed ( which is every couple of days now) as well as chlorinating tablets - I don;t use shocks or other powders. Everything else is fine and I check my water regularly. The level of stabilizer is also fine. Any other reason this is happening. I don;t want to drain the pool again so soon and have the solids go up so fast. Thanks for the advice, in advance.
