No insult was intended. I can see how it might be perceived as such, and I apologize. Children of all ages have a right to play with their toys and even to be foolish. Harmless foolishness can be great fun. Aquaristics falls into a different category, though.
Unless you are physically present, in a sense getting your hands wet, any intervention in aquarium operations or chemistry would be ill-considered, I think. There are exceptions, like automatic alternate power sources kicking in if there is a power failure, but there are limits to what should be entrusted to brainless devices, and to reliance on remote interventions based on what some hand-held pcd is telling you. Aquaristics is at least as much an art as it is a science. I've heard and read endless complaints about things dying even though "every parameter is perfect".
