Replacing water to get rid of CYA

[bbb]

I'm using the CYA test in the Leslie's DPD test kit (the one where you add water until the black dot at the bottom of the cylinder disappears). I checked it twice.

Great - I was hoping you were using the black dot test. I just wanted to make sure you were using the proper test, and not just a pool store printout or test strip, before going through all the effort of a drain/refill. As others on the post have said, if you get the CYA down between 50 and 100, you can certainly successfully run the pool (using the higher Cl amounts suggested in Ben's "best guess" table), so make your own judgement about the target level based on the amount of effort you want to put in, the cost and quality of your fill water, etc.

Good luck!
