pool green - chemical imbalance?

Duraleigh is on the money.

But it's always good to see our methods working-which they always do (unless there's something else at play).

okay, i did let my child test so here are my levels again a few hours later....

will get the other kit ordered.

TH: 400
FC: 10+
pH: 7.5-7.8
TA: 120
CYA: it is kinda in between the 0 and the 30-50 so i would say midway?

Test strips?

Then I have little confidence in them. Sorry. Drop testing works better. Drop testing: You add drops of stuff into a water sample.
