PSA : Check your Reagent Expire Dates

Yeah.

On the flip-side, TFTestKits sells all of the reagent refills and usually has a good sale in the early spring. So even if you think the old reagents are still working, you can pick up a fresh set for a good price and just not worry about it. Test kit reagents cost nothing compared to what people normally spend on a pool in a season. So trying to eeek out every last drop of reagent just to save a few bucks is mostly being penny-wise/pound-foolish.
More good advice. I've been on TFT all day debating between upgrading to a Pro kit (for the cool case) or just buying refills. I'm leaning toward buying the case + refill chems. Thanks again for the guiadnce.

If you have the stirrer, comparator block, vials and Googly Eye 4 letter word maker, then case + Tfpro refills is the way to go.

If they're all beat up and it's time for new anyway, then get the whole kit.
