Yeah, you don't need everything quite as precise as you seem to be shooting for. You could lower the pH if you like but I wouldn't (until it got to 8.0 which then becomes out of normal range). 7.2 - 7.8 is normal so just monitor it a little more carefully as it hovers around 7.8 and, if it's convenient or if it goes to 8.0, bring it down.
There are instructions in the kit to test for FC in .5ppm increments which will save some money on reagents but I certainly don't mind that you are testing in .2ppm increments, either..........I'll have two in college next year and will need all the refill orders I can get!!
How does your water look?
