Through the glass returns question

which is better running the returns over the top or through the glass? and if i do run the returns through the glass how do i keep it from siphoning out in case of a power outage? thanx alot

 

I have my return going through glass and to keep it from sucking out tank in outage Just drill small hole under elbow an make sure that part is out of water. But over the top works just fine also.

 

how far away of from the water line does the return go through?

 

not quite understanding this.

 

how far it sticks out of tank is only like one inch. this is just enough to make sure it can break any suction

 

it all depends on how much work you do. I would go through the glass if you could. but in that case you are going to want use a quality check valve, i am going to use two on my next tank. just in case on fails.

 

u mean using check valves instead of drilling the two holes to break siphon?


and 10acrewoods i mean how far down from the top of the tank are the holes drilled sorry if i wasnt that clear

 

ive got my hole drilled in the bottom of the right angle pc on top of the stand pipe it has never failed i keep a check on it every time i change the filter floss in the over flow just to make sure nothings growing in it..I canm put a pic of it if you like

 

My returns go over the top and I use a check valve.

 

are your holes drilled in the bottom of the tank, because im not sure i wanna risk drilling the bottom? im not sure the brand and if the bottom is tempered or not as it is a second hand tank. im drilling the back glass for the overflow and figured while im drilling for that i mine as well drill for the returns if its worth it. just not sure if its actually worth it and where to do it and how to stop a siphon from draining my tank to much.


to RemickJ do the check valves work good at stopping the siphon?
