Every one has to understand my replay is based on me being a mechanic.
The more stuff you put on your system the more likely there will be a problem.
I would never, ever, ever, ever, never, ever trust a dosing pump, salinity probe, electric ATO, any kind of computer related mechanism. Never. Unless a malfunction would be harmless. Like a roller filter or lighting.
I already have to rely on my heater and return pump controllers and that drives me absolutely bonkers.
The more you have the more risk and I know some are going to reply that it's actually less risk but you are insane.
I control everything that goes into my tank. I would never trust a pile of metal, plastic, wires, and chips. A power surge alone could wipe you out even if you have a protector. Ask me how I know.
Self driving cars, you can keep that too.
There is only ONE way I would trust any of that. It would have to be built by NASA with their standards of testing of life and death.
It takes me 20 minutes a day and 2-3 hours every other weekend to maintain my tank and that's fine with me. It's easier than our dog.
