unless you are doing a HUGE water change, having the levels somewhat higher in your salt isnt going to be a big deal, and most people with lots of consuiming creatures will still have to dose on days they do signifigant water changes.
Im in the same boat. I use RC and recently their new batches are insane on the alk........like 13. Im sure one of the big guns here knows specifically already or could write a formula for it with real hard numbers on hwo to deal with that, but how it works for me more or less is every couple of weeks when i pull my standard 20% water change, I will only dose about 1.5 ml a gallon of alk that day instead of 3 ml/g.
YMMV dependign on how much you consume. I could see that high alk really being a problem if your tank didnt consume much of anything and you did larger water changes
