Redundant returns?


New member
New to the group, thanks for info in advance. Building 90 g reef tank with Reef Octopus INT 150 skimmer. Plumbing it for two returns with one way valves so I always have a back up, but popular marine aquarium store near me says it's not necessary. Is having a redundant return overkill? Looking at VerioS, but not decided.

Two returns are popular in larger tanks but I've never heard of a valve being used inline as a backup. They are used to balance the flow back into the tank. IMHO it's a waste of money to shut down a return line.
Varios is a good pump.
