New pool owner trying to understand test strip reading

All you do is squirt a bit into the tube and glance. Then squirt more and glance again. It is low. Get yourself a couple of lbs of granular CYA and put it in a sock in front of one of the pool returns so it can dissolve. You can squeeze the sock to help it along. Give it 24 hours before you test it again.
Yes I did that. But the black dot only went away if I squirted harder and bubbles formed. It sounds like we have low stabilizer if it didn’t blur.

I have skimmer socks. I’ll use pool math and see how much to add. Thanks.

It is low. BUT DO NOT ADD ANYMORE RIGHT NOW. LET'S DO THE OCLT TONIGHT. Adding more now will make slam harder.
We want to rule out algae before you add more CYA.

We don't want to raise CYA until after we do OCLT. Higher CYA makes SLAM harder and more expensive.

Did you add it?
How much did you add in ppm?
How did you add it?

I did not add stabilizer yet. Was going to add it to a skimmer socks and about 2 pounds. But I will wait. Added the muratic acid about 45 min ago. Now adding two bags of salt. Then I’ll do my first test for the overnight test
 
WHEW!

Great! Fingers crossed. Print out the OCLT directions and follow them. Tests must be AFTER sunset and BEFORE sunrise. Use weather on your phone for the times.
Run pump 24/7, or at least 30 minutes before the tests.

Going to start it now. For SWG. Just pressing the less button until no % shows means it’s off right? (Tried looking in the manual but didn’t see it)

Dude, you didn't print out or read the OCLT instructions. Really need FC to be greater than 3ppm.

Do you have liquid chlorine? Then follow this from the OCLT instructions:

If your FC is less than 3 ppm, add enough liquid chlorine to achieve 3 ppm FC, wait 30 minutes, then retest with the FAS-DPD test.

It really does help, for new members to print out test instructions, OCLT, SLAM and keep them with you when doing the first time.

Missed that part. I was trying to figure out why yesterday’s reading was 4 and today’s was 2. I don’t have any liquid chlorine yet. I’ll have to go out and buy some tomorrow. I’m going to go out and test again now. Maybe it was just a bad reading. Still learning how to test with this kit.

Just tried again and it was 2.5 for FC. So I’ll have to stop and get some liquid chlorine to add tomorrow and do the overnight test tomorrow night

You have, at least, proven the reliability of the test. Good Job!

You will get there and the angst and time will greatly reduce. In 6 mos., you will say pffft, testing? Easy.

Also, instead of liquid chlorine, can’t I just up the percentage on my SWG. I lowered it a couple days ago to 20% from 40% after analyzing a test strip. Should I put it back to 40% tomorrow when I turn my SWG back on from adding the salt tonight?
