Very high FC

[RNeumann]

Opened the pool up starting last Sunday. Everything seems fine but the fc is very high 30+ (I stopped there because I was using a ton of reagent).
pH was 7.0 raised to 7.4

CYA was at 0 so I raised to 50.

TA 50

FC 30+ for 2 days now without adding chlorine. I've knly added 4 gallons total of 10% liquid chlorine since I've opened it. Had pump running about 75% of the time it's been open. Water is very clear and not irritating to swim in. I have ordered fresh reagents but same fc test results. Pool almost feels just barely slimey in some areas but not really and could just be baking soda, stabilizer, sand etc.

Whats up with the high free chlorine reading?

Also it seems a Bobby pin left some rust stains on my liner in a few spots. Is there anyway to clean these off?

Here is a picture of the rust spot.

How much chlorine you adding each day?
Never mind. Missed it.
Sounds Hinkey to me.

Maybe describe exactly how your doing the chlorine test?

10 ml sample, .5 ppm per drop of reagent right?

Yes that what ice been doing. I've used new reagents and multiple sample containers as I thought maybe the one I had was contaminated somehow.

I just went out and retested after swimming and I stopped at 40 (80 drops) as the pink was not fading at all. Seems very strange to me as I tested the water all last year with no issues. There is no smell of chlorine. Is it possible I have bad reagents? I ordered a new bottle of r-0003 off Amazon last week.

That is not the correct reagent for the FAS-DPD test.

Use the R0870 powder and R0871 reagent.

Okay, thank you for the answer. I will pretend like this never happened now.

. Laughing with you not at you! Hate it when I publicly display an oopsie!
Good news is these folks get us back on our merry way to a crystal clear pool!
