just wondering where to look when a pump larger then a hammerhead is needed? i know they make some large pond pumps but they're intended for freshwater use. thanks in advance.
 
I believe you can use just about any sequence pump, regardless of model, for saltwater so long as you use a saltwater seal. I believe they are universal to their pumps, but I would call them to make sure.

thanks for the response but i dont think i explained myself very clearly. if i were in need of a saltwater pump BIGGER then a sequence, were would i look and were could i find it?
 
What kind of gph are you looking for? How much head preasure will you have?

Look up aquaticeco.com and find the high volume pumps by Speck. Up to a 6hp single or 3 phase with saltwater seal and 1 hr run dry.

If that is not enough you must be building an ocean. LOL

I don't think I explained myself well either. Sequence makes pumps that put out well over 10K GPH! It depends on what sequence model you are looking at and what is your GPH requirement. The most popular models now common in the aquarium are not even a minute fraction of the pumps they manufacture. Give them a call, tell them what you are looking for in terms of GPH, and see what model may fit you best.

By the way, it would make it much easier if you said what kind of gph requirement you have so others can maybe point you in the right direction.
 
im really undecided on exact flow. im thinking soomewhere in the 10k gph area. im having a custom tank built in the near future and im just trying to plan ahead. the pump in question will be a closed loop. tank measurements are 108"x72"x60". i know i know, huge. but ive been saving for a long time and really want it.......but i dont think a simple hammerhead will be sufficient for flow. ill have a half dozen or so tunze to hit areas that the closed loop simply wont reach but i want the closed loop to be almost all of my flow. it will be set up penninsula style. i think ill use 3 returns with one main pump intake. i plan to have the three holes as following directly in the center of the tank:
one at 1' off the bottum, another at 2.5', and the last at 4'
now lets hear all the suggestions, id appreciate them
 
Hey Xdusty,

I was thinking of doing the cool whip bowl powered by the night light. Can you help me with the plumbing? I've always enjoyed the overstated!!!;)

airline tubing and jg fittings is the key lol!
anyone got any suggestions for what pump to use with my custom tank im having built?
 
You might want to check into something like this...

You know just for redundancy sake and simplicity instead of one big pump you might want to look into multiple smaller pumps. Otherwise look into the very large sequence and some of the pumps at aquaticeco. They have some monsters. Oh yeah also you may want to look at scewdrive units--I forget the exact term. Very large but relatively effecient which will be an issue for you.
 
xdusty6920--I have no input on the pump other what had already been stated. I just wanted to express how jealous I am :-) I hope you will share the build on the large tank forum!
 
I've got a Sequence 1hp pump that pumps 6000 gph in my hatchery and love it. They make bigger pumps than that, but this was all I needed.

Also, when you start going to pumps this size you are probably going to have to go with a 220 volt pump.
 
I think I'm done with this thread. Post some pics of your new tank when you get it. Pumps are only a very small part of the obsticles to overcome with a 2000 plus gal display tank. Weight, support, lighting, filtration, sump, humidity, scuba gear for cleaning....I hope you have plenty of room and deep pockets. If that is the case, good luck and I hope you post the project because I could learn a great deel from it.

I never understood things like this, maybe I'm missing something, but couldnt you plumb 2 darts in parallel, get 7200 gph, and use about 40% of the electricity? If theres a head hight issue, thats different, but I see people using 350 watt hammerheads on closed loops where 2 darts would be a better solution.

One of the things I was looking at on my setup was the head pressure of pumping water to 27 different tanks. The two Darts might have worked but I wasn't really willing to take that chance.
 
i had considered going with two or three smaller darts or the like but my main goal is to cover 80-90% of the flow through this closed loop and figured a dart wouldnt have the umph to supply flow from one side of the tank all the way to the opposite end of the tank, and from top to bottum in a 5ft tall tank.
yes i will start a tank build thread when the time comes. and yes i know there are alot of things to consider when putting together a system of this magnitude but the only one that really putting me in a spot that i must know (i have to tell him what holes, where and how big to drill in the tank) before i can actually start having the tank built.
 
im planning AO and have contacted will. any opinions about the pumps and flow situation im trying to iron out? anyone?lol
