Looks like a slight cost savings for me, even after adding in the testing cost. Compare the cost using the 10L size vs the 1L size; it's cheaper. I see several Pros to going with the Triton method even if it costs more. Time savings and stability increases are worth it to me. Using the 10L jugs will let me go around 130 days without having to mix stuff and refill containers for my dosing, which I have to do every month currently. Not carrying heavy boxes of salt down to my basement and having to stockpile them to avoid frequent orders. Less guesswork. I'm going to give it a shot.
