Please review my overflow

  • We are currently upgrading MFK. thanks! -neo
I seen in a few post that people moved their T up several inches to prevent air from getting into the overflow...... is that what I should go? I thought that would slow down the amount of water this would move.
 
Come on guys I need a little help. I just changed my intake length but it didn't help. Do I need to cap off the T thats there now and install a new one higher up

From what I can see is that your U pieces are not even meaning one is higher than the other. You want the u pieces to be even with each other. A mirror image on the inside of the tank and the outside.
So when the electricity shuts off they are even pressure on both sides and keep the water in the overflow.

The higher you make the T on the output the slower the flow will be. You want the T low as possible without loosing your prime when the electricity shuts off.

Having the U piece higher in the back will cause the water to back flow when Electricity shuts off and possible suck air in through the breather tube loosing your siphon.
 
If it were me, with a empty tank... I would drill it and install an inky box or something similar. I recently did something similar and thankful for it...

My U's on the bottom are even, the overflow will stand by itself. The pictures above were just dry fits and not seated all the way. I don't have a way of getting the tank to the glass shop to drill and I don't trust myself. Ya I don't want to drop the flow rate at all.
 
Ya I can't afford to repair or buy a new tank if I screw up. I do intend on trying it with something cheaper/smaller though. You can just hear my overflow sucking in air and my aqualifter does not keep prime I have to suck on the outlet hose of the aqualifter to get it started.
