Having an auto sampler would be great to have and I like the fact you can use test kits to perform the titration and you can corroberate the results by performing a manual test yourself.
entry #2: To be able to test as much as you want and not have to take the extra time is a game changer. You wouldn't have to devote hours to testing in order to have enough data to see trends and know exactly what your dosing is doing or what you need to dose.
I like the idea of the Reefbot because I'm finding, as a newer reefer, that I'm not testing parameters as often as I should. Automating the process would be welcomed.
