NEW QUESTION

I was doing some calc. amd did the one for Stand pipe size.

it said for 1000gph i needed min. 1.31" pipe. so Dual 1.25 will work great!

but it had a Min. Linear Overflow Size.
15" ????

what is that? the lenght of the pipe?

Click to expand...

Thats the amount of water that the overflow can handle, its calculated by measuring the top overflow section. Usually the length x width of the overflow. (you also need to factor in the slits in the top)

Heres an article on overflows. http://reefkeeping.com/issues/2003-07/gt/index.htm
 
Woo, Woo, Whats this topic all about?

What is a sump for? Seriously I'm curious. Is this a Bio filtration tank? If so ahhh.

I was looking at the design ideas for this tank, I'm assuming it is a bio filtration tank, I was thinking why do you require such large tanks to do this? For flooding in the event the power goes out to the pump? Why not use a pressure valve, in essense, the pump pressure is required to keep a ball loaded by a spring open, pump goes out, spring pushs ball closed not flood.

Maybe I'v got this all wrong?
