I have a brand new pool (finished 2 weeks ago) and just received my TF-100 test kit. Performed a test today and after wasting a bunch of solution (you're not supposed to fill the beaker with the dot to the top line with the solution) I have some results.
Last night I noticed we couldn't get the dirt off the floor of the pool so I cleaned the filter (after only two weeks it was a mess) and today the floor is clean. The water looks very clear.
Water temp 90
Air Temp 98
Thanks for all the great information.
