You mean 90, and 110 ppm, right?
If so, no, I wouldn't be concerned, as long as your pH is not too low. Make sure your pH occasionally is above 7.0, so you can be sure it's not t 6.2 or something like that!

Re: Dealing with scale problem
Yes, I meant 90 and 110 ppm. Guess I got carried away with the zeros. The lowest PH I've seen is 6.8. It has not been hard to keep it at 7.0 until the recent monsoons. Even then, 7.3 was the worst after our deluge on Wednesday.
