Hi, fish and fish tank lovers!
I am developing a battery-free pH meter. My hypothesis is that many aquarium owners who use hand-held pH meters would prefer battery-free solutions which are better for the environment.
I'm looking for data to support or reject this hypothesis (hence the poll) and any feedback about critical features or requirements to ensure we make something that is useful while being good for both the fish inside the tank and everyone else outside of it.
