Can you explain to me your plumbing? Did you do a pvc build or did you use an overflow box?

I like the overflow box but It kind of takes away from the biggest joy of this whole setup... it being cheap! haha
 
Okay so I got te drawer situation under control as well I have figured out my overflow.

I have decided go go with a 60 gallon sump and I'm running dual overflows into 2 separate drawers one on each end with the pump and heaters in the middle. I'm going to be buying a Danner pondmaster 1200ds pump that's rated at 1200 gph
It's a 150 gallon tank

So my next question is what size tubing should I use for my overflows? 3/4? 1? 2"?
 
you need to make the overflow so they can keep up with the flow of the pump. if your at 1200 gph, after plumbing you shold be around the 900 area, so build your overflow to atleast withstand 1000 plus gph just incase you want to upgrade your pump
 
When you say build my overflow, I think thats what I'm questioning. What size tubing should I use? and I should probably take into account that I'm running two seperate overflows (one on the left one on the right) and the the water is being pumped from the middle of my sump back into the tank. I'm just not sure as to what size pvc to use
 
thats what I like to hear since thats all they have at my local lowes...
Will I need to still run my cannister fluvall 405 with this huge ass sump or could I possibly sell this to reemburst me a little? lol
 
In the sticky about overflows it says that 1.5 inch pvc will produce 1350 gph downward force. If i am using two overflows of 1.5 pvc wont that total me at 2700 gph going into my sump, and I only have around 1000gph pumping back into my sump... Wont that be double what I need or am I missing something since i'm trying to use two something will equal out>??
 
1" PVC will be fine and also, on the overflows you need to put a ball valve or valve of your choosing that you can adjust the flow of the overflow to keep up with the pump that is returning. You can use this incase your overflows are going to fast and your pump can't keep up, this will allow you to restrict the water flow coming from the tank to your sump. Hope that makes sense :) It's very easy to do and once you have it set right, you will not have to worry about it.
