Congratulations, it looks like you did a great job!! Your numbers look pretty good, just don't let that chlorine drop below 3 ppm--if you do, you're inviting algae. With a CYA of 35, you need to keep the chlorine between 3 and 6 ppm.

When you do the alk test, you keep adding drops until the last drop you added makes no color change. If that's what you did, and 125 is the number, then that's actually pretty good. If you stopped before the sample stopped changing colors with additional drops, then you need to do the test again, this time adding drops until you get no color change at all. The alk could stand to come down a little bit, but it's not really bad where it is. If you keep adding acid to drop your pH, the alk will come down slowly anyway.

Good job!!
