Reef safe pvc pipe?

[NE reefer]

Hello everyone I’m getting ready to upgrade my reef tank into a 90 gallon system. I was in the local hardware store today and found these. Is electrical conduit pvc reef safe? I hope so because it fits perfectly.

Conduit is not intended to be used in liquid service but given the low pressures in a reef tank plumbing system it should be acceptable from a pressure standpoint. It does not carry the US Sanitary Foundation certifications for potable water, but I expect that it would be fine for a reef tank.
