Which Hammerhead?

[DarthOcellaris]

At the recommendation of someone and after some reasearch, I want to get the Sequence hammerhead pump

Should I get the 4500 gph or the 5800 gph? I've never owned one like this so I'm not sure if those extra horses are going to blow my application out of the water ( no pun intended ).

I'm going to drill several holes in the tanks for spray bars and the like...Most likely will be getting an OM8 way too. Would the 5800 be too much?

the 4500 is the barracuda. the hammerhead is the 5800

Hey Salty..I hate to throw you under the bus like this...

That's listed as 4500 gph...Fly, you're saying that's either a barracuda or a 5800gph hammerhead?

[DarthOcellaris]

Salty, did you change that listing or am I just crazy?! Now it is listed as the Barracuda :S

I must be losing it for sure LOL

Have you talked to Donny at 5th day. I am setting up a tank also and I was going to get an 8-way he talked me out of the 8-way and into a 4-way and just spliting the returns to give me eight.He gave me a great deal on a Dart maybe he can do the same for the hammerhead or Barracuda. It was alot cheaper than most online retailers.

Donny is awesome. I love that new store ! I'll go talk to him I think and see what his deals are like Thanks

there are certainly endless way to set those OM units up.

Just keep in mind the more you split individual ports, the more frictiopna nd head loss you are adding. If you intend to run spraybars off of a OM unit and run a 4 way, a 4 way wont work ery well, especially on a BB tank like darth is planning as you simply CANT split ports and expect to accomplish anything out of your spraybars. If you dont split it and DO accomplish something out of your spraybars, then you are left with 1 directional port out with full oomph in the tank at any given time. It is of course more compicated and random than that........but just the same

I have two 8 ways and wouldnt have it any other way on any size tank to be honest. drum cut 3 ports open every 120 degrees and a big pump. Sraybars are never taking more than roughly 1/3 of your flow at any given time, but it is dedicated fllow to them so they will do what you want them to.

moral to the story IMO.....splitting that 4 way is fine without spraybars, but you will have a lot less flow than you may think even at that. Not splitting the ports off of the Om unit, large outlets in the tank, and a pump that can handle some head pressure is where these things(4 ways or 8 ways) really shine

using a dart on any average OM 4 way plumbing set up you will be LUCKY to be getting 2200 gph of flow.....subtract even more depedning on plumbing creativity and skill. Darts cant handle the friction loss that a OM unit presents, and add a spraybar into the equation......save it...it simply wont cut it

oh...one more thing you need to consider here Darth.

Is your tank glass?? Im not sure how comfortable I would be drilling the 10 holes required for a OM 8 way into the back of a 75 gallon glass tank. Acxtually I DO know how comfortable I would be........not even a little bit

with that being said, a 4 way may be the way to go......you will be using a big pump so you can get away with a little more and splitting a couple of the ports may be an option......and if you did still go with an 8 way(or even splitting a coupl of the 4 wya ports).....i thinmk i would be considering bringing at least 4 of those ports up over the top somehow. I have some ideas on how that could be done very effectively if and when you get to that point

[DarthOcellaris]

uhg! You have a point. I need to think hard about drilling my tank with that many holes

[saltysupply]

scared me for a minute I had the wrong info up It's a challenge with so many products

[DarthOcellaris]

I usually double check everything too! LOL I must just not have been paying attention :S heh heh
