Test Kit for hot tub only?

[QuiltinMom]

I have had a TF100 test kit for a couple years. We initially had an above ground pool. We have gotten rid of the pool and now just have a 410 gallon hot tub/spa.

I need to order replacement chemicals. I feel like I won't use all of the chemicals, so not sure if a TF-100 refill kit is what I need or just purchase the chemicals I need.

I do have a SmartSpa SWG and do not currently have a way to test the salt levels. Is that something I should be testing?

What kits and or re-fills should I order? I was hoping they had a hot tub/spa kit, but so far have not found it.

THANKS!!!
