seio 1500

[Willow]

so i just noticed that seio has a new 1500gph model! i was thinking about a tunze but dang they are 69us for the seio. the only bummer is it takes 34 watts of power, i think the tunze is 18. i wonder how reliable these are going to be compaired to a tunze?

I'm realy happy with this powerhead so far! :smile: (Allthough I don't have the 1500 gph model)

Here's a thread in the other forum.

hows the noise like compaired to a mj?

I run a Mag18 on a closed loop and an MJ on my skimmer, afer adding the SEIO I couldn't hear any more noise at all.

I never ran it on its own though.

[Willow]

thats one of my concerns as i like a quiet system, i run a t4 pump as a retrun and its almost silent. so its good news.. now i just have to find one, anyone sees one around please let me know.

[Bob I]

I run a 620, it has been very reliable, and makes no noise. :biggrin:

620.. pffft you lightweight!

[Bob I]

30" tank makes me a lightweight by necessity. :eek:

Hey Bob,
Do you think the 620 is enough flow for the 30" tank or would you buy a 820 next time..?? :confused:

[bear27]

Im running a 820 in a 50g(36" tank) and have to say that I am very impressed with these pumps. they are silent cant hear them running at all

[Willow]

so i guess the 1500 would be about right for my 90?

My 620 is supplemented by the return of a Fluval 304, but I would probably get a 820 if I had to do it over. :biggrin:

[G1GY]

The 820 makes my 90 almost too turbulent! The 1500 would be waaaaay overkill IMO.

Since I added it, skimmer production has almost doubled! (I guess more junk is staying suspended rather than just laying at the bottom.)

I think you might regret using the 1500 in a 90.

[Willow]

i was reading on rc people putting 2 1500's in 90's :eek: from what i understand there is some flow adjustment. i dunno, i cant eve find one know anyways. i'll make some calls tomorrow.

[AJ_77]

J&L out of stock already, or did they get stock? :confused: are they carrying only the smaller ones...

also try reefsolution.ca, maybe he's getting the 1500s in.

[G1GY]

You ditch the outside housing and that flow director that you see in the pic and use it naked. :smile:
It's only half the size that way and totaly unrestricted.

If you want I'll send you a pic of it with the stuff off of it tommorow.

[Willow]

yeah absolutely that would be great!

i don't think they ever got any.. they just came out a few days ago.

You can see if these guys have any..??
Looks to be one of the cheapest places Ive seen. (And Ive been looking... :cool: )

The 820 makes my 90 almost too turbulent! The 1500 would be waaaaay overkill IMO.



I have two 1680gph tunze and two 820 seio's in my 3 foot long 90 gal and I can't feel a hard current anywhere.. depending on the price I would replace my 820's with the 1500's in a heart beat.

Steve

[muck]

Steve,
You are running an SPS only tank right?
I wonder if what you are running now would be too much current for softies or some of the LPS corals out there... :confused: Thoughts..??

Steve

So your saying you have 5000 gph worth of powerheads in your 90 and no hard current anywhere?

That might be fine in your glass bottom set up, but what if you put some substrate in there?

Sorry, but I have a hard time beliving that turning over the amount of just about the whole contents of the tank every minute does not produce a hard current.

[Willow]

im sure if you had a decend sized bed you would have a huge cloud. im running 20lbs of sand in my 90 and mostly going to have softies and lps.

nope I am saying I have 6800gph flow in a 90 and just a gentle current through out the tank. I had almost the same flow in my 90 when the sad was in there but it was concentrated in the top 1/2 and then did make some massive flow that still wasn't to bad. I would not go back to a sand bed if you paid me now.

[Willito]

1500's in a 4 foot tank of SPS is fine, but maybe too much for Softies. 1100's would be more ideal for softies. I have both of these models in my odd-shape tank I like it alot better then the 820's. 1100's are not much bigger then the 820's. The 1500's are noticably larger and heavier. Both new models run as quiet as the 820's. On start-up the new models are alot louder, this is an issue to consider when using on timer. Overall function and appearance of the new models are identical to the previous models.

[G1GY]

Here's the pic of the SEIO 820 with the flow director housing off of it for you willo. :smile:

i run 2 620 and 2 maxi1200 my 620 are kinda noisy and i have to say doesnt seem like they push much more then my maxijets

[StirCrazy]

you mean a 3 foot tank :mrgreen: but honestly with a 70X turnover rate there is nothing more than a gentle current. you watch some corals and the polyps are barley moving, the mushrooms are out and full. this is why I am thinking of replacing the two 820's with either tunze 1680's or the 1500's If I swap them with the tunze that will give me a 90X flow rate and if I leave them in with two new tunze it will be about a 110X flow rate.

I think right now I would not have a problem with any LPS or softies with the 70X turnover rate.

Now if I still had a sand bed I would not have been able to get it this gentle as it would be keeping sand suspended 24/7 so if you have a sand bed maybe stick with the 820's in the top 1/2 of the tank

[hockey nut]

So what would everybody recommend for a 4' 120 gal? 2 x 820 and a couple of mj 1200 on a wave maker? or something different?

:cool: thanks

how tall is the tank and what kinda of sand are you using?

[Azilla]

Just curious with the houseing off should i put both pumps on each side of the tank and face them to each other???? i have 2 620

I've seen quite a few people do it that way. Won't hurt anything to try it.

[hockey nut]

Hi Steve,

It's a 48"x24"x24". I'll have about 2 to 3 inches of sand. I would like to keep clams and some various types of monties, shrooms and maybe an acro or 2.

I will be running a mak 4 for a return and then i was thinking a seio 820 and a couple of MJ 1200. The MJ's would be on a wave maker.

let me know what you think and thanks for the help.

regards

I hear u cant run SEIO Pumps on a wave maker

Perfect for reef, planted, or heavily stocked feed aquariums.

Note: These pumps are not designed to be used on a wavemaker!

[G1GY]

Hmmm.... Interesting.

Where did you hear this?

[Azilla]

read it on the sites that sell the pumps.

[G1GY]

Thanks. I didn't know this. :smile:

[Willow]

im trying to find out if j&l will bring one in for me. thanks for the pic gigy, that looks like the best way to mount them hey?

i think they cant be run on wavemakers because the constant on and off demagnetizes the impellors.

[PrairieReefer]

I can verify that they can't be run on a wave maker. I had 2 820's, and a MJ 1200 on a wave maker in a 75g tank. It made for really nice chaotic flow in the tank but the 820's lasted less than a month. There is a plastic tab on the impeller (inside somewhere). The constant on and off just chews up the tab and then the pump won't start. The plastic jams against the magnet and won't let the impeller rev up. If you take the pump apart and physically loosen the plastic from the magnet, the pump will start once and continue spining until power is removed. It then will not start until it is taken apart again. I am lucky. The store where I got the pumps is replacing the impellers under warranty. These pumps are great, but definitely not for use on a wave maker.

[Willow]

i called j&l, they said they wont bring any of the larger ones in untill they sell the smaller stock off :frown: might be awhile before i get one. maybe jack can hook me up.

Maybe PM Willito and find out where he got the larger ones.

Steve,

Are you sure you had a sand bed at this time and not crushed coral or something heavier yet?

I'd be realy interested to know how you had that much water turn around and no hard current.
I mean I know you can direct the flow from the pump in any direction, but how do you prevent having a torrent of current in a 3 foot tank with that much flow?
Do you have the powerheads behind a big pile of rock?
Maybe the tank has 3 or 4 pounds of rock per gallon of water that works as a baffle system?

Do you use a wave maker type of set up on the Tunzes? (If so, then the off time has to be figured into your gph figure.)

I'm still wondering how you don't have any hard current with that much flow.

Some of my fish (CBB and Yellow tang for example) have a real tough time maneuvering around when their in the path of the 820 in a 3' tank and more flow would surely make it that much tougher for them.

So please tell me your secret. :smile:

[StirCrazy]

Steve,

Are you sure you had a sand bed at this time and not crushed coral or something heavier yet?

yup 230 LBS of sugar sand, right from salt water connection.



I'd be realy interested to know how you had that much water turn around and no hard current.

Define hard current? when I had it all in the top 1/2 of the tank there was lots of hard current, but no jet blast.



I mean I know you can direct the flow from the pump in any direction, but how do you prevent having a torrent of current in a 3 foot tank with that much flow?

basically the Tunze went across the length of the tank pointed at each other, and then the 4 maxi jets intersected the tunze. and my return, returns via 6 1/2" nozzles.

No that the sand bed is gone I have one tunze on the top back left side blowing across the top of the tank, one tunze on the bottom right size blowing across the bottom, one Seio on the top front left side blowing across the tank and one Seio under the back bottom right side of the rocks blowing under them to remove the crap from under them. the strongest current is across the front bottom of the tank and the tang loves going down there. it is still slow enuf that he could hover there and eat algae off the bottom when it was there.

with this set up you can put your hand anywhere and all you feel is a gentle push on your hand



Do you have the powerheads behind a big pile of rock?
Maybe the tank has 3 or 4 pounds of rock per gallon of water that works as a baffle system?

I reduced my rock to about 150 to 170Lbs of rock in a 94 gal tank. only 1 Seio is under the rock and that is to flush it out



Do you use a wave maker type of set up on the Tunzes? (If so, then the off time has to be figured into your gph figure.)

Nope a normal wave maker will kill a tunze also. and the ones I have are not set up for that use. all water movers are on full 24/7


I'm still wondering how you don't have any hard current with that much flow.

there is a current, but one that is the size of the whole tank not just a nozzle blast.


Some of my fish (CBB and Yellow tang for example) have a real tough time maneuvering around when their in the path of the 820 in a 3' tank and more flow would surely make it that much tougher for them.


I find that hard to believe, in the ocean the currents make my tank look like a joke and they still manage to swim there. My yellow tang used to sit in front of the Tunze about 2" off and hover there and the 820 is only 1/2 the flow of the tunze.
