    TC AND FC----TEST STRIPS

    As of today i only have test strips to check my cl, i plan to order the test kit recommended. So should the fc be equal to the tc on the strip. these are the only 2 on the strip. the test shows my fc is greater than the tc. i know this is terrible info,but any help today would be a blessing. THANKS.

    My suggestion is to get a quality test kit. Take control of your pool and the H2O contained within. You have the ability...aloha!

    It isn't possible for FC to be greater than TC.

    You can head to Walmart and get a 5way kit that at least uses a drop test for chlorine till the "good" one comes in.

    It is impossible for the FC to be higher than the TC. This is just one reason why using test steps is bogus. Without knowing an accurate Cyanuric Acid (CYA) level we can't tell you if it is safe to swim -- with no CYA it would not be safe, with a higher CYA it would probably be fine. Of course, that assumes we could trust the FC reading at all, which we really can't. See this post for a comparison of the resolution of test strips vs the two drop-based tests we recommend on this forum.
