High Free Chlorine (FC): Over 30

[PoolStored]

Good to go!

I cleaned my pool water container and vial with alcohol. I held the reagent bottle vertically. I used only 5mL of water.

A couple questions, even though I’ve been testing my water on my own for a few months. (I have a tfp auto stir device)

When I’m adding drops, sometimes the test will go clear and almost immediately turn back to light pink. I assume that the test needs to stay clear for longer than one second to determine FC level.

I’ve read that the test water can turn back pink after sitting for a bit, but that’s not what’s happening.

Also, i looked at my equipment today. While the panel shows 0% output, my physical intelliclor is completely lit up. See photos.

Thoughts?

Once the sample turns clear, test is over. Even if it turns back pink after a few seconds.

Ya'll, I'm so frustrated. I've done all the things to perform the most accurate test and my FC is at 35. Should I be adding less of the DPD powder, if I'm just doing a 5mL test? My panel still shows 0% on the intellichlor, but the actual intellichlor equipment is completely lit up.

"0125", I haven't been following your thread, but I'll try to assist. First, if you are using the 5ml water sample as a temp measure to save on reagent, no more than one scoop of powder. That is plenty and won't cause a high FC reading. Your cell is on max output. Is that what you are intending? While it's still a bit warm in TX, the sun's angle is lower, so you might need to lower that output. Unless you are doing a SLAM for algae, have you considered turning the cell off for a day or so? Let that FC drop down to about 10 or so at least?

No, I wasn't intending max output on my cell. Previously, when I tried the buttons, they weren't doing anything. Even had my pool builder guy was out here a while back and he couldn't figure it out. However, since you had mentioned it, I tried the buttons again -- and they are working!! Wondering if I had to change the salt output to 0% of the panel to get the buttons on the SWG working? Dunno, but happy that I tried again. My FC is finally going down. I'm at 17, so I'm HAPPY!!
