I have a RedSea Reefer 250 and whenever I turn off the return pump to feed my fish, it creates a powerful vacuum when it sucks water back into the sump.
It makes me worried about the safety of the fish in my tank since the force is enough to tear a small fish in half if it gets too close.
Is there a one-way valve I can get that attaches to the return nozzle? I've seen check valves mentioned in some searches but it's hard to find reliable information.
To be clear, this has nothing to do with water filling the sump, that's not an issue, it's entirely to do with the sucking being dangerous to fish.
