I am currently plumbing my sump and tank (40g breeder and 20L glass sump).
Return pump will be an Eheim 1260 in the sump.
Do I need to have something under the pump to insulate it from vibration?
I have a scrap piece of insulating styrofoam (blue board used to insulate exteriors walls for a house).
Would this work (and is it reefsafe) or is there something better?
