What do people think about the automatic water testers that are currently on the market? I know the mastertronic essential just came out and the reviews seem pretty mixed with a bias maybe leaning towards more unhappy customers. Then there's the trident and trident NP series but i'm currently on hydros and would have to switch over to neptune's ecosystem which would be financially painful haha. The Maven just seems like a false promise at this time. Anyone have any recommendations?

The biggest question is what do you care most about testing or what parameters are important to you? All testing has downsides and their own flaws.

I had the reefbot a long time ago. First revision. It worked pretty well for a couple of years, then died.
Nice that it tested a lot of different values.
New version looks pretty nice.

I switched to the Neptune Trident. Also old version.
That worked well, and had a big advantage that it could control Alk/Ca dosers automtically.
Very handy.

That said, as I go to a smaller tank in the future, I am not bothering.
For a large tank, it was worth having the auto warnings and doser controls.
For smaller, I am just going to stick with auto-water-exchange, no dosing, no worries.

What do you plan to use for the auto-water exchange?
