Nope, even tho 1in is capable on a good day to handle 1200gph you cant guarantee it.
when sizing a pump consider the head pressure, and how much of a turn over you want. the figure a turn over you need to really see how big of a bio-load you have... or planning on having. I personally run a 4x and its overkill for me... my over flows can handle well over 4000gph but my pump is a 1000 with a 6ft head pumping 800gph (roughly) i can safely go up to 3000gph with out any issues... the over flows will get air in them will slow down with time...
so make sure you add in a cushion for safety... unless you like cleaning up floods....
having the siphons in the tank open a the bottom is easy to do, you just need to set the t on the back to be at your water level...

see i dont get all that head pressure, etc. is the overflow GPH just a max? lets say i build an overflow rated at 1200 gph can i use a pump rated for 800 gph without any problems?
yes, but that pump would be pumping around 5-700 depending on how high the pump has to pump that water.iloveoscars702;4156261; said:

it will probably be pumping water up about 3 ft.
so pretty much the overflow gph really depends how fast the pump pumps the water back in?
i have a 125 gal stocked with a silver and jardini arowana and 6 bichirs how big should i go? i was thinking of a 1.5 pvc overflow with a pump rated at 1200. is that good, should i be worried about the sump overflowing, etc with that idea?!?
all i am concerned about is the sump overflowing, etc.
yup...iloveoscars702;4156627; said:
that should work, personally i would run 2, 1.5 overflows, so in case one loses its prime the other is there to save you.iloveoscars702;4156627; said:
the sump wont overflow, your tank will. the over flows will flow as fast as your pump can pump water in... until it reaches its max capacity. So the higher max you can get you overflow the bigger the pump you can run.iloveoscars702;4156627; said:
so for example
my over flows can handle 4000gph, my pump can pump 1000, my overflow will overflow 1000gph into my sump and my pump will pump 1000gph into the tank...
if i trow another 1000gph pump into the sump my overflow will toss back 2000gph into the sump...
if i trow in 5 1000gph pumps into the sump and my overflows can handle 4000 then i would have alot of water spilling out of my tank...
the biggest reason, why you don't want to run a 1000gph pump on an overflow system capable of handling 1000gph, is because if you get air in your overflow the over flow can no longer flow 1000gph... so you end up with your tank spilling water over... but if you were to run a 500gph pump you can afford that small amount of loss in your overflow and just maintain your overflows once a week with out any real worries, so if you run two overflows that can both handle your pump alone you truly have nothing to worry about...
... does that make sense?
