Siphon Break in Loc Line?

[mark]

why don't you run your pump, top up the sump to normal level then power off adjusting the Locline to get an how much backflow your sump can handle.

Yeah thats a good idea. My sump can handle a decent amount for sure.

I was just hoping to keep the return quite low in the tank pointed behind some rocks but I don't have to. The sump for sure would not be able to handle that kind of back siphon.

I have mine setup so the locline nozzles are just piercing the water surface, gives a cleaner look and you don't need to drill holes. I've always seen problems with siphon holes, they require constant cleaning to keep them from clogging and they can sometimes create a little rippling noise. It's kind of like relying on a check valve, best to avoid them all together.

I have a 1/4" or so hole drilled in my Locline but I like sphelps' idea better and when I re-do my plumbing that is how I will do it. No worry about the siphon brake hole blocking and less ugly plumbing in the tank.

Yes this is how I ended up setting it up. Seems the best.

No back siphon, nice surface agitation and creates an insane amount of shimmer now from the halides. Plus as you said, You don't notice it at all.
