Maxi-Jet 900 & 1200 - that much diff water movement?

Brent Thomann · 01/25/2006, 10:01 AM

Going to be adding a few of these to my setup and was wondering if there is much of a difference in the water movement between the two pumps.

The 1200 is rated at 295gph and the 900 is 230gph. But the 900 uses less then twice the watts, 8.5 Watts compared to 20 watts with the 1200.

Trying to get the least amount of watts possible but if there is a big difference in the 2 pumps then I'll unfortunately have to get the bigger 1200.

Was also going to maybe get 1 tunze 6060 (11 watts) to run full time and have the maxi-jets on a time wavemaker and possibly have my internal water current at only 36.50 watts, thats if the 900's close to comparable as the 1200's.

Thanks!

I found a pronounced difference between the 900 and the 1200- fwiw.

If you can afford the Tunze, the rest is a waste of time IMO. Assuming you are on a budget you might want to look at the Seios as well. The Seio M620 pushes 600gph for 8 watts.

Thanks, looks like I'll be replacing the 900 or 1200 with the Seio M620

Entropy · 01/25/2006, 10:56 AM

Just keep in mind you cannot put it on a wave maker! I have one in my 150g and it is a nice pump. Very quiet, and pushes a lot of water. You might also want to look at the M820's or even the 1100's for your size tank. I didn't see you had a 180g. You can add a lot of flow to that tank.

I have three of the 820's and a 620 and I am thinking of adding a couple more 820's.

Brent Thomann · 01/25/2006, 11:04 AM

How would a moded Maxi-Jet 1200 compare to the Seio M620 in my case?

I would like to put a pump on each end of my tank trying to get it to cover my rock. I was either thinking doing a Seio M620 (1 on each end) and have the water rotate back and forth across the rock or modifying a 1200 (one on each end) setup on some type timed waver maker.

If needed, for a little extra water movement I was going to maybe put one tunze 6060 (under $150, 11 watts) on one end and have it run constantly.

Here's a pic of my tank- (still setting things up, current pumps you see in the tank are temporary, 1000gph are coming through the 4 Hydor Flo's you see going across the top of the tank, my returns.) 180 gal, 40L sump/refuge, 220 lbs of LR

Entropy · 01/25/2006, 11:25 AM

Well like I mentioned, if you can afford the Tunze I would go with that. You will not fine a better power head IMO. The price tag is just hard for some of use to swallow.

If you are going to spend money on the Tunze though, I would suggest you get one of the controllable versions. Otherwise I think the Seio is a better buy. You could go with dual Seio 1100s in that tank, one at each back corner. The 1100 uses more power than the comparable Tunze but you can get two for the same price and it will take quite a while for the power savings to make up for it.

sm fragman · 01/25/2006, 11:40 AM

why not a tunze 6060 or 6080 that is what i am leaning tord ,other than the seios ,,i know they are not controlable but a much better product dont you think

Entropy · 01/25/2006, 12:01 PM

Yeah I think the Tunze is a better product but the price is a killer. The 6080 is $200!!! and is still uncontrollable. I would rather have a couple of Seios and keep $120 in my pocket, but keep in mind I sell stuff on eBay to afford to buy Ca supplements.

BCool · 01/25/2006, 12:04 PM

have you looked at a maxi jet mod with propellers, a 900 will put out about 1500 ghp. There are threads in the DIY section about it.

Entropy · 01/25/2006, 01:24 PM

Link? That might be a viable option and you could put them on a wave timer.

Right now I can't afford the tunzes. What I really wanted was 6000x2, 7095x1 = $738.58 @ MDepot. But I already dropped a couple thousand in the last couple months setting up the tank. I even built the stand/canopy to save. My wife would kill me, she almost did when I told her I bought $800 lights. Could only imagine if she found out I spent over $700 on 2 pumps, ha.

What I'm thinking for now dual M620 (cheap), 1 in each back corner and then a couple months down the road maybe adding 1 Tunze 6060 or even 2 if needed. I already get pretty good water movement from the 1000gph coming through the 4 Hydor Flo's. They rotate the water 360 degrees. How's that sound to you guys?

BCool, will look into the maxi jet mod with propellers. Sounds interesting and I'm a DIY kinda guy. I have 2 pumps running the whole setup, at about 100 watts. 1200gph Rio HF, 60 watts and a sedra 9000 (rated 40 to 50 watts w/ needle wheel impeller -PS). I also came up with a way to run my UV Sterilizer off my ASM G4 Skimmer so I didn't have to run another pump for it. Oh, Skimmer is feed from my overflow too (no extra pump). Lastly, I'd love to throw in no pump on my auto top-off either, 80 foot direct line from my RO/DI Unit in my basement on a float valve.

Entropy · 01/25/2006, 01:41 PM

I think it is a good plan, but I think you will be happier with the 820's. The 620 is smaller physically which is nice, but the 820 has a little more water movement.

BCool · 01/25/2006, 03:29 PM

Look in the DIY forum, the thread is called Hitchhikers guide to the maxi jet stream mod. Basically you set up the maxi ala tunze or seio with some pvc and hobby boat propellers on a carbon shaft. Basically for 50 bucks you can do to 900's that will put out 3000ghp combined. They have videos of some that are going. Lots of dispersed good flow.

http://reefcentral.com/forums/showth...92#post6584792

Read it, they are very good. People that have done it really like them and have had them running along time. Yes with some more modification you can run them on wave timers. There is a current discussion on wavemakers with these mods going on right now.

Entropy · 01/25/2006, 03:32 PM

Thanks for the link. Not sure I have the patience to set that kind of thing up, but it is worth looking into.

BCool · 01/25/2006, 03:40 PM

If you would rather buy one modded people will put them together for you. It'll cost you though, probably more than a seio. If you wanted tons of flow these can be reallly cheap. With duel 1.75 inch props you could move a ton of water probably over 2000+gph with a mj900 and 20 bucks in supplies.

Sounds very interesting. Once I get a chance I'll have to do some reading. Let you know how I make out!

Brent Thomann · 01/27/2006, 09:26 AM

Hi Guys, I ordered a couple M620's (lower watts) and 2 MJ900's to attempt the Stream Mod. The mod keeps improving as I read the thread, took all night to get through half of the one thread- "Hitchhiker's Guide". Then there's another thread on the same topic with different notes that I'm sure I'll have to go through "DIY MaxiJet Stream (Pic Intense)". I sure wish there was just one to follow. I want to make sure I build it the best way so that I get the maximum flow out of my MJ900's.

BCool, so far I don't think duel 1.75 will fit in the MJ900 mod. The housing is 1.5" PVC so the prop would have to be smaller than 1.5"

BCool · 01/29/2006, 11:57 PM

If you use a 1.5 inch coupler you can use 1.75 inch props. It is in the forum that I posted.
