Assuming that those test results are correct, you probably ought to lower your pH to 7.2 -7.4 -- you're awfully close to levels where calcium carbonate can precipitate, clouding your pool.

Also, you do NOT want to crank up a salt system with no CYA in the water. Unless you have a massively oversized SWG, there's no way it can keep up, with the sunlight consuming your chlorine as it will with no CYA.

Of course, this assumes that the test results are correct. From what I gather from seeing Leslie's results posted here, their stores are somewhat erratic. You might want to take in a second sample, and see if they get more or less the same values the 2nd time. If they do, you'll have better reason to trust their results.
