If it's a vinyl pool then Alk is not a problem. If it's concrete or plaster or tile, you'll need to lower it.

With a CYA of 100, you'll have to maintain your FC between 8 and 15--you're now a 18 so you are fine.

pH is a little high, but that may be an artifact of the high FC of 18--but it's still in normal range.

About the only thing you should do is wear last year's bathing suits as the higher level of chlorine may fade them.

In short: For a high-CYA pool, your numbers look pretty good. Try adding to drops of the # 7 reagent to your pH test before your add the 0014 reagent. That's chlorine neutralizer and two drops neutralizes about 10ppm of FC--you have nearly 20. You may get a lower pH.

If your TRUE pH is lower and you have a vinyl pool, AND you are willing to maintain a high CYA pool, then I think you are just fine and good to swim.
