TF Test Kits R-0871 for 2025

[Turbo1Ton]

I purchased the reagent refills earlier this year when they were on sale. I also have a friend who just purchased a TFPro Salt for his almost completed pool. I gave him a bottle of my pool water to play around with testing with, so he could see if he was getting the same thing I was to confirm he had the method down. Oddly he tested double the FC that I did. I was using up my old reagents from last year though, and had yet to start using this new batch. So I broke out the new R-0871 bottle and sure enough, it was double the FC that I was getting with the old bottle of R-0871. It also appeared that the drops were coming out about twice as fast and half the size as the old bottle.

A quick email to [email protected] late last night, and Nate responded first thing this morning and let me know the new bottle shape causes static electricity buildup and it causes tiny drop sizes. Asked me to touch the tip of the bottle as I was dispensing a drop and I would feel a slight static shock and it would fix the drop size. Sure enough, I ran home for lunch and did this, and it worked!

I did a quick search to see if anyone had posted about this yet but didn't see anything, so wanted to throw it out there for anyone who may have the same issue.

Thanks to TF Test kits (@Sarah and Nate ) for the quick support, and a huge shout out to TFP for being the best pool care resource on the planet!!!

I make the recommendation all the time to wipe the tip of new R-0871 with a wet paper towel. It is also in the Wiki.

If you have received new reagents, the bottle can have a static charge that decreases the droplet size, increasing the results of the test (more drops). With new reagent bottle, evacuate a bit of air from the bottle, invert, and use a wet coffee filter or paper towel to wipe the tip of the bottle before performing the test. This removes the static charge, allowing a normal droplet size.

Overshot FC during Slam - how??

This pool season has been a doozy for us - winter leak, hard opening (successfully completed slam), broken laterals in sand filter, SWG died, and now performing another slam after noticed slippery floor and failed OCLT on Saturday. I tell you all this because this forum has been so helpful...

Knew this about the R-0009 but never realized it was common for other reagents as well. Thanks!

Seems to be a one time thing when received from shipping. Works fine after That.
