210 gal pump suggestion

[steveo32]

OK well Im new to this side of the forum. But any how I am going to be setting up a 210 gal tank in the very near future and am wondering what pump to use. I orginaly had a 125 reef with a iwaki 70 and found that I had so much head pressure the pump was not really producing hte required flow. So I was thinking of using a sequence Hammerhead becasue it seems like it will work and the price isn;t that bad either. I will be having the pump and sump/refuge located in the basement. The display tank will be upstairs on the man living floor. I calculated aproximetly 20' of head pressure to the tank outlets. This includes all of the 90's and T's, I also accounted for the restriton of pipe be used. So does this pump seem sufficant or will I need a bigger pump ? Als ois this a good pupm quality wise ? thank you all

It depends on what you want to keep in the tank also. If you want to keep SPS, you might want to go with a little more flow, bigger pump. If It's a FOWLR, you might be alright.

Generally, you want 3-5 times the tank volume turnover through the sump. So you need to find a pump that gives you ~650 to 1050 gph at 20' of head....The Hammerhead shut off is at 23'...so I would cross that off your list. If you want sequence, maybe a Wahoo or Marlin. Your Iwaki 70 should put you in the area of 900 gph...If it doesnt, then you have more then 20 feet of head, and maybe need to jump up to an Iwaki 100, or Pan World 250ps....

Additional flow should come from power head or a closed loop.

Well i was reading this chart and I thought it says that @ 20' it pumps 2400 gph but I could be reading it wrong

And it will be a mixed with some sps mainly lps

Oh geez...I dont know what I was looking at. My Bad. Your right.

But that brings up another question, what are size are your drains and returns?

 

[steveo32]

well the drains are one inch and the returns are 3/4 so that is another issue that will have to be aaddressed. maybe throttleing down the pump but idk
the main concern was getting enough flow at the tank

 

[Fiziksgeek]

I also have a 210...let me guess AGA? 2-1" drains can only handle around 1200 gph.

My recommendation would be to use your Iwaki 70 as the return, and plumb in a closed loop or get powers head (tunze) for the extra flow. If you do a closed loop, you can run a smaller sequence (maybe a Dart) and keep that right under the tank. That way you are using the pump more efficiently...not loosing all that flow to head pressure.

 

[steveo32]

yeah but the closed loop defeats the purpose of have no pump up stairs and that brings noise plus I will loose alot with trying to get the intake lines and output right ? argh idk what to do I not even supposed to be upgrading lol I never finished my 125 thats why Im starting a new venture
