overflow box

[JimmyJohn]

Ever since ive been doing my fish tank for about a month everytime i have to siphon its the hardest thing to do. I have PVC pipe running from it to my fuge and its the hardest thing to do i have the over flow that hangs on the back and i have to take the front box off and hold the tube over the sipon hole an put it in the tank and then open the valve under the tank very complicated is there an easier way of doing this so its not so complicated?

i just put my mouth on the tube coming out of the bridge of the overflow and suck the air out to close the siphon

Does your box hold a siphon. Once you get it going you shouldnt have to do it again. if you have to start it up all the time what would happen in a power out?

You have to stick a piece of airline tubing up into the high spot of the utube. Then put it in place and suck the air out through the airline tubing. Hurry and pull the tubing out. With practice it should take no longer than 10 seconds.

i have an aqualifter plugged into airline coming out a hole on the top of the utube. its always on so it starts the siphon if there's ever a power outage or if i happen to break the siphon when doing maintenance. its a pretty useful thing. i hate starting siphons by sucking, it always take me forever and i always get shocked when the water comes down and i end up spilling water all over my face and the floor!

Back when I used that type of overflows, tube and formed I had some little check valves you could put into a hole in the top of the curve and them attach airline to the other side of to suck the air out. Leave the tubing on for the next time needed or take it off, the check valve would remain closed and keep the syphon. Like kraze3 says you shouldn't have to start it every time the pump shuts down if you have good sealed unit.

A properly designed U-tube overflow box should hold its siphon at all times. (( unless you remove the tube yourself. ))

I have a LifeReef one, in the 7+ years of having it, it has never lost its siphon -- excluding me removing it.
