seio 820

jbittner · 02/06/2006, 10:33 PM

Is a seio 820 to much flow for a standard 55???
I have a maxi-jet 1200 in the tank and a mag 7 as a return
Softie reef tank with t5 lighting

definitely not too much...don't be scared by the 800 gph rating...you might even want to go higher...they move a great amount of water but at a lower velocity so that you don't blow stuff out of the tank...i have a 820 in my 45 and am probably going to add another one...i really like them, a more economical version of the tunze...although i would not reccommend running them on any type of wavemaker...

In my 50 I have 1 Seio 1500, I seio 820, 1 Seio 620, plus my mag 7 return. My tank is a SPS tank, but if I had a softie tank I would go with 2 seio 820 's plus my mag 7 return. The seio's put off a nice gental current which is ideal.

Difinitally not too much,

I have an 1100 and a 620 in my 24 gallon............

IMO, Not to much the 620's seem to put out to much less than a 820.

bigbenji · 02/07/2006, 02:58 AM

I never liked the flow from the MJ1200, because the flow just blasted things around. Now I've got 2 seio 620's and I have to put my hand in front of them to make sure they're on. The flow is so drammatically dispersed, I'm thinking I need something bigger.

Why not? Seriously, I just bought a wavemaker for the seios. Is it the problem with restarting thing?

It says right on the power plug (and in the instructions) that you can't run them on a wave maker because it destroys the powerhead. They have been working on a wavemaker that works with the seios for a long time, and swear that it will be out soon.

Yep, that should do nicely for you and not take up as much space as a bigger one and use some less watts for your electric bill. I had a 55 with a Mag7 and two MJ900's which worked out well, so I would think you system with the MJ1200 and the 820 would do great. Keep you MJ1200 though, the Seio sometimes don't power up after a power outage, even if it is a quick one. You sometimes have to give them a wrap on your palm once or twice under the water to get them going again, so mount it an an easy space to get at. You should also run it tunze style to get the best flow from it, the stock way it comes only runs at about 60% of rated flow since it immediately takes a 90 degree turn.

I have a Mag 7, 2 1100 Seio's and 2 MJ900's in my 90g, and have lost power a couple times here and there. I just love and am thankful for having my MJ900's since they always kick back on to keep some water movement besides my Mag 7.

rjwilson37 · 02/07/2006, 09:06 AM

I think that will give you around 1600gph, which is almost 30 times your tanks volume for water movement.

Craig Lambert · 02/07/2006, 09:14 AM

I put two 820's on a 75G that I just set up this weekend. The flow is great, and the tank has a dsb as well. It also has a poseidon T-2 return, which is on par with a Mag 7.

If you talk to taam, inc. (the manufacturer) they will tell you that if you do run them on a timer, expect to have to replace the impeller assembly often, it will wear it out. I have a 620 (for periods of calm) that if it goes off, it must be started by hand. I don't turn it off, but you think having to reset your alarm clock when the power goes out is annoying?? (wave2k in my 75 moves better than 3000 gph in purely laminar flow - seio 620, maxi jet 900 and return running (all the time) when wave2k is off)

All of my MaxJets are running with Hydor deflectors on them... That will take care of the blasting issues....and it will also give you a nice alternating flow pattern ( they rotate )...

I also like the Seios ( I'm running two 1500's in my 150gal tank ) and like it's been pointed out already, you currently "can't " run them with a wavemaker... Even the "soft start" wavemakers are no good for them.

A Maxijet 1200 uses 20w, and a Seio 1100 runs at 21w. I like pushing 1100gph around for the same wattage that pushes 295gph. As long as you don't lose electricity a lot, the Seio's work great and for less wattage you can push more water. I do suggest though that you have a MJ in the mix somewhere preferably the MJ900 since it only uses 8w to keep water moving in case of a power outage.

MJ900 times 3 Equals 24w and pushes 690gph.
MJ1200 times 2 Equals 40w and pushes 580gph.

1 MJ900 8w and 1 Seio 820 18w Equals 26w and pushes 1050gph.
1 MJ900 8w and 1 Seio 1100 21w Equals 29w and pushes 1330gph.

fishman805 · 02/07/2006, 05:02 PM

Thanks rj for the power ratings.... But in my case with all the stuff I've got running, I ain't too worried about 24 to 40 watts more.... But if wattage is a concern, then nothing beats a Tunze... Very low power consumption and alot more options as to flow rates and controlability...

I just could not afford the price tag when I first started out.... LOL.. still can't. I'll have to sit down sometime and figure out exactly what I am pushing.... Given lights and pumps and all probably close or just over 1500 watts on my 150gal... What's really the issue is how all that equates to current ... "that's" where the money issues come in to play.... And in the case of powerheads and pumps, it's "heat" ( again current ) that's most important to keep out of our tanks ....

But you're right rj, you get more bang for the buck using the Seios as apposed to "only" using maxjets.... I've got four different types of pumps running in my 150gal ( mag2400 for return...two Seio 1500's... one MJ1200, and two aquaclear 800's )..
