I'm about to purchase the tf-100 test kit +XL option. it comes to $97 and I need to spend $100 for free shipping. what single reagent should I add to push me over my $100 mark?

I figured I could save $50 and just shake the bottleDid you order a magnetic speedstir? That's a must have.
It is really that easy, and people did it for decades, but trust me it is SO nice to press a button and only have to count drops.figured I could save $50 and just shake the bottle
Weird. I’ve always run out of 870 first. Perhaps that’s because I do a lot of hot tub testing in the winter where the FC may be lower than normal if you’re testing a pool. Or I’m using too much.Testing doesn't happen in a closed bottle, it happens in an open test tube. Swirling while dropping is absolutely possible but if you're in TFP you're going to save enough on everything else that many people here treat themselves to the speedstir. It's available on Amazon cheaper.
To your actual question, you'll run out of 0871 first (for the chlorine test).
Or get an extra test tube and a plastic spoon.
