I was looking in my kit and I am running low on the pH drop test reagant. I have seen the same test kits at walmart. Will this test kit work the same as what is in the TF100 kit. The only reason I ask is that is all I need as my other ones I just ordered recently.

The ingredient is the same (phenol red), but the concentrations are different depending on the size of the sample to be used. You'd have to replace it with the same number Taylor reagent (R-0004, I think).
