I am going to use black tubing for my return since I can make a sweep over the top of the tank (not drilled) & the into pvc inside the tank. If I do this, should I drill a small hole in the tubing just under the water like you would w/ pvc fro a siphon break? Or should the pvc come over the top so I can drill that?
Also, should you drill a siphon break on a c.l. system as well for the "just in case"?
Thank you,
Chris
