fuge overflows

luvnpc69 · 12/07/2007, 02:32 PM

i am setting up a fuge on my 55 gallon that uses a powerhead in, gravity overflow out method...do i need to drill holes near the waterline in both the in and the out to prevent reverse-siphon overflow in case of power outtage, or just in the out?...thanks

The out shouldnt be a problem if its gravity fed... The in probably needs one if it is pumping up to the fuge...

why not the out as well? i have one in the return from my sump/filter for this reason...i figured it would be the same thing for the fuge....what am i missing?

Are you using an overflow Box ???

i use an overflow box to my sump...return with magdrive and hole drilled in return pipe...setting up a fuge powered with a pump in, gravity overflow back out,, how do i keep this from overflowing with power outtages?

You don't need to drill any holes if it's hanging out the main tank, if power goes out, water level will be at the same as the tank no spills on floor

If it's gravity overflow out of the fuge and into ??? ... then there is no possibility of overflow of the fuge during a power outage b/c the input (the powerhead) won't be running. Once the powerhead stops running the water level should balance out right below the line where the gravity outflow starts.

is it not possible for a reverse siphon to start since both pipes are under water in the main tank?

Maybe a picture or diagram of your setup would help us understand your concern a bit more.

here is the instructions to the fuge i have, complete with a diagram...this will be a hang on addition to a 55 gallon tank...nothing fancy...don't know if the link will work...if not, hope you can just copy and paste

I actually own the same item you are showing. I have the Large model hanging on the back of my 75gallon tank.

During a power loss the fuge will drain back into the main tank via the input side only until the water falls below the top of the baffle that separates the input tube's chamber from the middle chamber. Which is about 50% of its volume.
