Water test results?

[arwsgirl]

Since this isn't our pool I'm hesitant to buy a test kit so I brought water in to the pool store (I know you don't trust those results but its the best I can do). We had the filter running 24/7 for 2 days (SWG) to clear out the green. It looks great now but the test says the FC and total chlorine is 9. Is that because of running the filter for 2 days straight?

Total Chlorine 9
FC 9
pH 7.4
Alkalinity 85
CH 75
Stabilizer 70
Salt 3400

Should I do anything or leave it?

As long as the water is clear and there are no signs of algae, you are fine.

The SWG runs a set percentage of the time the pump is on. If you increase the pump runtime, the SWG ends up producing more chlorine, which explains the slightly high FC level.

But it's still safe to swim in at those levels? And do I need to mess with the CH level?

You can swim all the way up to shock level. So if that CYA reading is correct (Big IF) shock level is 20, so you're good to go.

If this is a vinyl pool, low CH isn't a problem.
