What size pump

im setting up a 39 gallon and im not sure on water flow,how many gpm do i need to push in to it and how much would be over kill. thanks

 

are you going for hang on, sump, or cannister? and on my 28 i got a 100 gallon cannister filter and my water is pristine. i got it off ebay like 50 bucks

 

just finished my Sump/refugium project and im trying to get the rest of it goinglike what size bulk head to use water flow and so no.

 

You want your sump to run 3x to 5x your tank volume. If you are keeping softies and LPS 10x to 20x turnover including sump return. SPS you want 20x and up. Some running SPS only do 100x.

 

well i got my pump now, 600 gph what size bulk heads do i use?

 

600gph is a LOT for that tank unless you are not taking head loss into account there, then it might be more appropriate. A 1" bulkhead should handle it fine. Consider putting a gate valve on the output of the pump as well so you can dial it back if you need to.

 

If I were you here is what I would do.. Use 1" pipe to keep it uniform and have plenty of flow. Get some pvc ball valves to control your water coming in from the tank and out from the pump(to control flow rates).. Also dont forget to install a few Unions so you can take your plumbing apart if need be. As for bulkheads, go with 1", maybe larger on the drain bulkhead.

Hope this helps, and welcome to the forum

 

Also dont worry about 600 gallons being too much.. I had a 950 gph pump on my 30 gal, and I could run it wide open without a hitch..

 

Yeah, there's nothing technically wrong with running extra gph through the sump but it's just not necessary and using extra electricity and adding more heat to the system.

 

well my thinking was to run every thing off one pump ie less electricity and less heat .if im wronge please let me know.
so how many bulk heads do i need if i use 1" bulk heads
