Initial TF-100 Readings

[houstonguy]

Just got the TF-100 the other day and after getting familiar with it and doing some more pool school reading, I'm comfortable that I have my first set of accurate numbers with the test. I had used a combination of a PH/FC kit and test strips before this. Obviously, some of the numbers are drastically different that what the test strips were showing. The only thing that is really off target is the CH level, which were showing about 250 with test strips but doesn't seem to be nearly that high.

Ph - 7.6
FC - 6.5
CC - .5
TA - 110
CH - 150
CYA-60

Any advice beyond what the pool calculator recommends? Is it a good idea to have the pool test my water just to get a comparison?

Thanks!

Other than CH, everything looks great.

Trust your own testing. Doing your own testing with a top quality test kit is much better than using the pool store.

With such a big jump in CH needed, is it best to adjust it in several stages to make sure I don't overshoot the target??

How long should I wait before retesting after adding calcium chloride?

Thanks!

An hour with the pump running should do it.
