fishcatdog66, 70HD would be too much pump for the skimmer. The air draw would be too much for the body. I tried a Blueline 40HD on my 48" and on my 30" with a 15" extension and both skimmers couldn,t handle that pressure rated pump (had to throttle the output off the pump back halfway with a ball valve). On my 30" with the extension I am running a Blueline 30HD and pulling 20-22SCFH which is perfect for the skimmer.
Thanks for the info.Ya,why ask for trouble right?If it ain't broke...
That's why I went LifeReef in the first place.
