My anecdote: I owned three Nero 3sfor my AIO. They worked well. They did get stuck with snails, but it wo uld error out. I wish only that the magnets be stronger.
As for the organization of components into different “tanks” is weird. Why can’t I have an aquarium named Reef and add all of my Primes and Neros?
Within a tank they should add groupings so we can group components we want to work together.
For example “(object) User Provided Object Name”
- (tank) ReefLivingRoom
- (group) Lights Hi
- (group) Lights Lo
- (group) Lights All
- (group) Nero3 Back
- (group) Nero5 Front
- (group) Nero All
