Overflow/Design Question

Hey All,

I am workign on a new coral tank - going to be 48" long by 36" wide and 12" deep. I plan to have an overflow dead center in the tank. I have an overflow question for you.....I plan to have a 1" bulkhead leading to my sump. What kind of riser pipe do I need in there? I have the megaflow tanks now, which have really fancy riser piped for the drain into the sump...they are adjustable, with elbows at the top, air vents, etc. That definitely will not fit in the space I will have to work in. Can I just put a 1" diameter PVC riser pipe in there? Any reason why/why not?

 

Yes, but you may face gurgle noise with just a 1" standpipe. Look into the durso or gurglebuster to silent your overflow.

 

Go with a larger return to your sump - 2" if you can fit it. At least get 1.5". This will allow TONS of flow and will help to cut down on your "toilet flush gargle" that is seen when gravity fed lines are at their capacity.

Hofer Gurgle busters are great . . . .Hofer Gurgle Buster

 

Cool thanks

 

and Regular good ol' Stock Schedule 40 PVC will work fine!!
If it is exposed - I would suggest going with Sched 40 or Sched 80 CPVC - it is gray and will be a lot less visible from outside the tank - not to mention it is nearly indestructible!!! But it is slightly harder to find and is definately more expensive.
