Understanding numbers...

[StephenRMcKay]

Hey guys,

Just need some clarification on numbers in pool math.

So my FC Level is 4 (as per my test results yesterday). When I go to pool math and use the 'effects of adding' feature, I asked what would happen if I added 3 gallons of 10% liquid chlorine. It said it would raise my FC levels by 10. 10 what? Does that mean my new level should be around 14? Or am I missing something? I'm sure it's simple, just need some one to spell it out haha. Thanks in advance.

yes that means your fc will increase by 10 ppm, which will bring you up to 14 ppm

you can also use poolmath to get the same thing.. current FC 4 and target FC 14 and it should come out to 3 gallons

If you log your test results they will show up on the main page then when you select the fc tab it will show your current reading & your suggested target - it will take into account your last logged cya level. You can switch the toggle to slam if thats what you’re trying to do.
