Hmm zennzzo not quite sure what you mean by your idea, but looking at it i really dont want a 4" PVC in my tank, trying to minimize clutter in the tank so ya. Also it would be hard to set this up as you have drawn up, im assuming you want to attach the 4" PVC through the bulk fitting as well? Im just not sure how its going to work. Also is this an intake for the water if so any reason for the 4" PVC being long and that close to the bottom of the tank?
Final Large Tank Setup Need Last Advice
- Thread starter fish-boy13
- Start date
The 4" is attached to the back wall, by the 1" fittings plumbed inside, into the bulkhead fitting...
This is an overflow.
The water will go in to top, skimming the surface (good)and fall into the long 4" overflow.
The water pressure will be the same as it is at the bottom end of the tank (good) untill enough water drains to below the skimmer teeth.
When the water level drops below the teeth it will quit draining into the 4" effectively stoping water draining (good) especially if the power goes out...

I've seen a couple of other setups like this in which bioballs or scrubbies merge directly with a finer type biomedia below the waterline. Since the top of the media tower is capped off by mechanical media and the bottom is sealed by the waterline, it seems to me that each media tower is now effectively sealed against air circulation. I would imagine that within such a structure, the depletion of O2 and accumulation of CO2 would be fairly rapid and would thwart the intended aerobic metabolic activity within the wet/dry stack that you are trying to achieve.
brianp, i think i know what you mean, but the stack will not be completely sealed off from aeriating the bio media between each drawer there is a slight gap. Also not all the bio media will be submerged into the water only about 1/3 and a bit of it will be.
Now does anyone have any ideas of how to solve my other situations?

I like the idea Zennzz, Never thought about using PVC to create the overflow.
For the vent hole I referred to, you put the hole just below the water level of the tank. Yes, the water will come out of the hole, but since it is under water, you will never notice it. You wouldn't even notice a difference in the output of your UGJs.

Hmm...is this from experience cuz to be honest im assuming even if it is under water im still thinking in my head it will shoot out a ton of water even if the hole is very small. Well btw its a RUGF now would that make a difference in my situation?

Well i still need my question 1 answered and here what people think about it. Also the last question that includes a very important part and that would be the pump and so on.
Q#1...I think you will find that your water level will be hard to maintain at the level you have illustrated...with either of those outlets the water level will be right at the bulkheads...fish-boy13;2212470; said:
Also I am unclear as to the spray-bar plumbing, from the drawing it looks like the center riser goes up out of the water and terminates...
Well my plan is to have the bulkheads drilled 2" from the very top of the glass, so the top of the hole is measuring 2" from the top of the tank. Now ill be attaching a PVC pointing upwards to the right height to give me that right amount to match my pump.
Now as for the spray bar well it is pretty much a pvc running up the rear of my tank and just hanging over. Not sure if thats your question. Could you elaborate more?
