Just a quick thought. I wish they made a clear body for classic eheim canisters. That would make a great reactor. I was just think of the reactors that I’ve seen and some of the possible failure points and maintenance issues. Eheimcanester are super reliable, easy to work on and already proven in many ways. I would love it because you wouldn’t have a feed pump, the shut off valves are easy. Also, mechanical and additional chemical filtration. Just a quick fun thought.
