Hey Saltn00b anyone can use the OceansMotions nozzles.....Which ones are you referring too??? I used both type on my setup.....The ones that rotate are called "revs", and they flexible nozzle types are called "omni nozzles"....The revs are nice, and with them not being hooked to an OM, I would say they would spin constantly.....They wouldn't have the drop down motion when pressure was applied to them and they wouldn't pop up as well only because there would be constant pressure applied to them......
I'm not really sure what your referring to when you say I made some tall "U" shapes to prevent back syphon on my CL...... :thinking: A CL won't back syphon if it's a true CL.....
The (2) 2" bulkheads drilled in the back of the tank and plumbed down to the pump that feeds the OceansMotions, and then the OceansMotions is plumbed back into the tank.....Therefore there is no open pipes or ends, so even when the power goes out which has happened it doesn't drain down, because the CL is a continous circle or circuit you might call it.......Water drawn down to the pump and pumped right back to the tank.....
You would have back syphon issues with water being drawn from a sump or what not, but again that wouldn't be a true CL, and that's why I advise people that ask about feeding the CL from an overflow against it for those reasons......It's not a self contained system there is a break in it........
Hopefully by next weekend I'll have the new pump in place for the CL.....I'm not happy with the Dart running the OM.....I listened to the builder and shouldn't have 2nd guessed my thoughts......HammerHead will go
