Refugium Help please

[firemedic0135]

Just got my refugium up and going and only have one slight problem.
The return line hose siphons water back into the fuge when it goes off. so if I lose power I am gonna have that thing draining my tank much further than the overflow could ever do.
BTW the return line is pumped by a rio 1100+.
diff pump mabye?
Bring the return head to the top of the water mabye?
what have u done?
thanks again
John

Drill a siphon hole in your return line just under the existing water line, power goes out, return line sucks air thru the siphon hole, and stops the siphon. HTH

Nice I did that exact same thing that night. Only prob was it was jetting bubbles from the weep hole so I stuck a piece of foam around it.
Thanks

Does it still break the siphon with the foam around it??

[firemedic0135]

yeah it fits real loose just snug enough to stay put.

What kind of foam did you use? The reason I ask is that I have a bunch of siphon holes and I do get some bubbles. Do you have a pic, or can you get one?

[firemedic0135]

yeah I can take a pic for ya.
I got the foam from my overflow box and just cut off about half an inch.
i will post a pic here in a minute.
