CRAZY Overflow Idea

[Amaroq]

FRONT VIEW

The very top black pieces at the far left and right are where the piping goes over the top of the tank and connects to the other far left and right pipes tipped with black.

Do you think this overflow idea will work? The VERY top bar out of the 5 in FRONT VIEW will be where the overflow will top sucking once they reach the very lowest hole on the top bar correct? and it should restart after a power out? Im REALLY hoping this plan is plossible because then i wont have to worry about dead water zones where the intake pipes wont be able to reach the gunk, for the most part atleast. One more question, this would be for a 55 gallon tank and i want to have 750 gallons per hour filtered so 1.5 inch pipes would work? and for a pump i think i want one that can pump 900 gallons per hour to compensate for all the piping, does that sound about right?

Thanks Guys,
Spencer

Nope, as it is it will drain your tank to the bottom. You need to go up to the top like a normal pvc overflow then connect your grid there.

Theres nothing to break the siphon until it drains past the last pvc pipe...

OHHHH Ok, thanks guys it was worth a try atleast that would be a sick filter dont you think? And about the piping and pump any ideas?

Hm actually i have another idea LOL What if at the back i put a few like 6-12 piece of airline from the bottom PVC pipe and stick the airline to the tank wall with some suction cups and once the water gets past the airline tube it sucks in air luss breaking the suction?

well, i would think that then the overflow would suck air into it so that it cannot restart itself after a power outtage. Unless you have a powerhead or something to use as a Venturi but i dont know if that idea will work in the first place

Is there anyway i could just drill some holes at a certain level on the "main" intake pipes? so when they hit there depth the suction is broken? By the main i mean the far right and far left intake pipes

The problem is the same thing that you'll find with UGF's. The water is going to flow through the path of least resistance. The restriction of the smaller holes is going to make balancing the flow rate of the pump and the overflow very difficult. Unfortunately, though the idea isn't a bad one, it won't work.
