Testing hot tub water again today using FAS/DPD. 8 drops turns it all clear and then it turns pink again. Scratching my head. Just keep adding drops?

Can u be more specific? 8 drops turned it clear. Before I could start the CC test it was pink again.
In my pool the FC is at 8-10 ppm always and the sample remains clear

No specific factors. Ignore it.
CC test is not needed unless you are finishing a SLAM process.

I did a CC on hot tub yesterday and showed 4 so I wanted to repeat it today. Just a few unusual things happening
CC can bleed through on the FC test.
Are you on bromine or chlorine?
Are you using MPS non-chlorine shock?
Do you have an ozonator?
If yes, what model?
What unusual things are happening?
See above posts. Sample turning pink after it turns clear so I can’t even do a CC test
Using liquid chlorine.
I use some non chlorine shock once a week. Having 4 CC yesterday very unusual.

Once it goes clear (colorless), the FC test is complete even if the sample goes pink again.
Proceed with the CC test immediately after the sample goes clear.
When was the last drain and refill?

Fresh N Clear will cause high CC readings.
It is an oxidizer only - it does NOT sanitize the water.

Thanks guys. Refilled 2 months ago. I use liquid chlorine daily and toss 1/2 caplful of clear and fresh in on Fridays. Never had CC before and never had water sample not stay clear. Water is clear as bell 300 gal

Have you tried running the hot tub the same way as you run the pool - and not add non chlorine products to the hot tub? It may take a bit more time initially, but once you get into a routine it should be easy.
I just did a few cya tests and for some reason it’s at 80-100. I’ve never added stabilizer and when I stopped using powder chlorine ( has cya) my cya was around 30 ( unless I did test wrong back then. I think I’m gonna drain 1/2 tub at least at start again with full tests
I also use the frog ease and I think it may contain CYA

Yeah - that isn't the best to use. Consider removing the cartridge inside of it.
