I get electrical alerts if something shuts off or if its power draw is outside of my parameters. If say a heater was leaking current or exploded in the tank and I can shut anything i need to off remotely. If my water parameters are off, the mindstream should be able to tell me that. I don't run a chiller or calcium reactor, just don't see what a controller offers me personally. I want to keep things simple so there is less that can and will go wrong. If my tank springs a leak and I'm at work, what is the Apex telling me that my floor is wet do for me? I'm not there to do anything about it.
The mindstream website also states that it is in talks with controller manufacturers (GHL and Neptune I suspect) to integrate their testing with established controllers and that the unit already has the capacity to do so built into the units that are shipping. If that is the case and I can set up a dosing pump to keep my water parameters in check automatically, i might consider an actual controller but then again the GHL stand alone doser may function in that regard anyway if it is GHL compatible.
We each manage risk differently but for me, the cost of the Apex and the added functionality far outweigh the relatively small cost. How do those alerts work with the heater? If it stays on for x hours, you get an alert? If it doesn't go on for x hours, you get an alert? If not, you could end up cooking or freezing your fish if you don't also get temperature alerts. My Apex has saved my tank from total disaster any number of times over the years in situations where there would be no electrical draw alerts. My low and high sump level float switches have prevented the tank from overflowing or the return pump burning out. The temperature sensor has shut off a heater when its thermostat broke in the on position. And my moisture sensors have turned off an RO/DI when the float switch stuck overflowing the storage tank. Luckily the moisture sensors under the 340g tank have never been triggered, but if I got that alert, I'd get my butt home in a heartbeat if only to witness the disaster in real time!!
I'm also excited about the Mindstream and it would be great if it was integrated with Apex simply from a tracking standpoint, but I use a CalRx so would not easily be able to take advantage of that added functionality.
