Ah heck I'm probably gonna order all 3 and try them out anyway. Just because I'm a dork more than anything
I also emailed JBJ asking about the wattage ratings on them. D. |

dude I gave up counting the splits long ago Also did you order all 3 versions of the pump? |

ya . mainly because they are different dimensions.
you should order them too : ) mine should be here by monday because im so close to PA. |

I tried some of those jbj dual outlet powerheads and found them lacking. I wish I knew you were going to order some, I would have sent you a couple used ones.
Maybe you can do something with that powerhead to make it usable |

AHA... I got a response back from JBJ
"The sp-1300 is 18watt with 240gph, the sp-1800 is 25watt with 290gph, and the sp-2500 is 32watt with 530gph. Also any pumps can be used with a protein skimmer, as long as the flow rate is correct. If you have any further questions please email or contact our customer support line and someone will further assist you on this matter." So far so good a bit higher power draw than MJ1200 but not too much. |

I just ordered them by the way. Very curious to see how the SP-2500 can be modded. At 530gph stock, this thing could be a monster once modded

Well, I attempted to drill the center of the MJ magnet in order to make the hole more centered. It was a futile attempt. I ended up breaking the magnet in two pieces. That really jacked me off since I don't have a spare laying around. This project is starting to cost just as much as a couple of SEIO 1500's. (as most DIY projects do) Though I think that If I can get these to work silent, I'll be better off than with the SEIO's anyhow. Restart problems, and just the general expence if a coil burns out make the MJmod a better option... If I can get it working to my expectations and don't have to fiddle with it every 2 weeks.
Anyhow, I epoxyed the magnet back together (It's probably stronger now than it was before) and I need to wait for it to cure and I will drill the center for the shaft, and carefully epoxy the CF tube directly on the top of the magnet. It should be fine as long as I am very careful to get the whole thing centered just so. Has anyone found a source for tubular magnets like this. It would be nice to not have to buy the whole MJ impellor assembly when a dummy like me decides to go medieval on the magnet. OK, next thought. Who thinks that the shrowds on the MJmods are entirely too long? I think that the longer the shaft, the less tolerant this mod is for errors in balance and centering. So I had thought after making the one I am working on now at a standard length, I would try to make a new shrowd about 1/2 the size of the large ones that come with the 1200 MJmods. I know that the smaller shrowd may limit flow a bit, and I am definitely going to have to increase the size of the inlet slots, but a shaft and propellor assembly that is 1/2 the length should be much more stable. That's my theory anyhow. -J |

BTW...
I'm all ears if anyone has a good idea for making sure the CF tube is completely centered when I epoxy it to the magnet. -J |

yep, i'm slow... I didn't know that mjmods was selling a small high flow shrowd now. looks nice.

It would probably be better for you to just buy a new impeller instead of gluing that back and re-drilling it. Impellers aren't that expensive to begin with.
I also don't think it's a good idea to drill the magnet either as you have found out, it is very brittle and will break quite readily. From my own experience the MJ400 and MJ600 magnets have perfect circular holes that are centered while the MJ900 and MJ1200 have somewhat oval holes instead. The holes maybe oval but they should still be centered so there really should not be any need for drilling IMO. |

By the way for all intents and purposes, the original build method of using the flex airline tubing to connect the magnet to the propeller still works just as well as the new "tube in magnet" build. Just be sure to remember to use the black airline tube that came with the original Maxijet instead of the clear airline tubing and you should be fine. With the original build, it is the clear flex airline that eventually stretched, gave way, and failed whereas if you're using the black tube this won't happen.
So instead of pulling out your hair trying to drill the magnet I would suggest trying the original "simple" build first. Just my 2 cents. |

Anyone do a test yet of a Maxi-jet Mod vs. the Nano Stream 6025?

I don't have access to a nano-stream otherwise I would
Wanna loan me yours? |

I don't have a Stream Nano 6025, but at a price of around $60 for the Nano 6025, I'm wondering whether it's worth the time to do the Maxi-Jet Mod. I do have a lot of Maxi-Jet 1200s, but you should see all the DIY reef stuff I already have in my garage

The 6025 puts out 1189 gph, according to the info at Premium Aquatics

I just reread the specs and I was wrong.
Nanostream Design is much more than only styling of existing products: It is the expression of an idea and a concept; it opens one's eyes. Turbelle nanostream combines aesthetics and function. This innovative circulation pump sets new records: At a diameter of only 70 mm it enables a water flow of 4,500 l/h (1,189 USgal./h) at an energy consumption of only 8 W. The pump includes a very large strainer for the intake which prevents premature soiling. The spherical shape permits an ingenious 3D setting of the direction of flow. As a standard feature, Turbelle nanostream is supplied with a magnetic holder, which enables uncomplicated attachment at any position on the aquarium pane. The speed of the Turbeller nanostream 6055 can be controlled by a Singlecontroller or a Multicontroller; in addition, they have been provided with a fish care function in case of motor standstill. 6025 & 6045 are not controllable. Turbeller nanostream 6025 For aquariums from 40 to 200 litres (11 to 53 USgal.) Flow rate: 2,500 l/h (660 US gal./h) Energy consumption: 7 W Voltage / frequency: 110V/60Hz (115V/60Hz) Cable length: 2 m (78.7 in.) Dimensions: diam. 70 mm (2.7 in.), outlet: diam. 40/15 mm (1.5 / .59 in.) |

uhhhh....

Yeah, it's the 6045 that pumps out 1189 gph, but it's about $100. The think I really like about the nanostreams are these two features:
1. The flow looks like it can be easily directed in a wide directional range. I've had to jury-rig my Stream 6000 series mounts to direct their flow upwards. 2. The magnet comes with the nanostreams. But I'll probably try out a Maxi-Jet mod just to see the performance.
