Hello,
Looks like Mastertronic came out with an updated version of their automatic tester that tests: Ca, Alk, Nitrate, Phos, Mg, and water clarity. Just wondering what if anything anyone has heard. The original had mixed reviews and some issues. This one looks promising for an all in one. BRS has it on sale for $910. The reviews on BRS are pretty negative, but they are all over a year old to 1.5 years old.
The most recent video I found was from June 2025 which is more of an unboxing and not a long term usage review.

 
I owned the original MasterTronic. Too many reagents to manage, too many moving parts, too much to calibrate. You also can't really trust the Mg tests anyway, and I don't need to test nitrate/phosphate that often.

Now that it includes Alk, it might be a compelling purchase for new tanks to keep an eye on things while they stabilize. But for an established tank you just don't need to invest in that level of testing at that frequency, other than Alk.

I am a big fan of both the Alkatronic and Dosetronic from the same company, FWIW.
