Pretty slick with the PVC housing.

It's 1.25" ID. It's probably sturdy enough for the mod, just not as sturdy as what you have. As for the hole sizes, they're about 1/8", but so are the plastic sections, so the holes are about 1/8" apart. This is why I doubt that it will allow more flow. A matter of fact, the flow was too low to use it as a U-tube strainer so I took a razor and enlarged the 1/8" square holes to 1/8" x 1/4" This worked better, but made the whole tubing flimsy. Flimsy doesn't matter for a strainer, but for the MJ mod it will compromise structural integrity. Although your idea for bracing may work.dhnguyen said:

I looked at those pictures from the other site, and DANG!! That is some sweet milling on those PVC pipes!!! The only thing that I can see potentially wrong with those is the width of the cuts is really narrow. I forsee coraline and algae growth potentially causing an issue with those.

Yeah maybe... But I like the slotted cuts on that better than the holes. More openings for the water inlet while remain somewhat unobtrusive. Plus it looks better than my Swiss cheese design :lol:
Maybe I should just try to find some slotted PVC pipes instead.
Anyone know where to get these at? The ones shown on aquaticeco is too big.

Look down near the bottom of this thread. The guy made slots and it looks really really nice.

I am going to attempt to make some additional ones out of Aqua Clear 401's with 1.5" black ABS drain pipe, and a 1.5" prop. So far the MJ 1200 that I modded is working well, and seems to have increased its output since I first set it up???
I plan on taking pictures and detailing the Aqua Clears if I successfully create one out of them as they are setup differently than the MJs..

I need to get my hands on some cheap-o powerheads because I am itching to give this mod a try, but I cant justify (or afford) buying a brand new powerhead just to tear it apart - even if it will end up better. Time to start scouring the used equipment forum(s).
Just a quick question - someone asked earlier about the increased flow rate, and quantifying it. I'm interested in giving this a scientific analysis, but I have no idea how I'd measure the flow out of this thing. How could I objectively measure the flow out of an unmodified MaxiJet and then the modified one? I'd like to compare a performance increase, and also see how it would work on a wavemaker for randomized flow too.
Hmm, now i just need some free time to do it!

If you set up an empty tank with saltwater, and put something that is secured at the base like plastic plants, you can observe how much they bend to the flow of a regular powerhead vs the modified one perhaps.
Or point it up and see what it does, then point the other one up. Either way, you'll get wet.

The clear piece at the end of the PVC that has the red thing in the middle of it is the top brace for the impeller shaft. Effectively, the impeller rotates around a shaft (in this case, it is modified to a shaft of carbon fiber). For the shaft to remain in the same place rather than vibrate out of the housing, there is a tob brace to keep it where it needs to be. Without the top brace, there is a high probability that the impeller could go flying out or the shaft could pop loose.

Haha, yeah, I'd definately get wet. I did that on accident with my Seio 2600. Needless to say, a saltwater shower is not as refreshing as a normal one.
I think I'll have to do something more modified than "plants" but something hanging in the water to measure the angle and somehow convert that to a force. I guess, my goal is to somehow quantify it into something meaningful - obviously everyone is fairly happy with the increased flow, so I'm not trying to prove it wrong or show contrary info. I plan on using the modded powerheads in a frag tank I'm setting up.

If you had a large body of water, and placed a very thin membrane bag of say 50 gallon size in empty, you could use a stop watch and time 1 minute of fill time and then measure the amount of water the pump pumped into the bag, then multiply by 60minutes and it should give you an idea of flow through volume..

That, as well, is a good idea, and actually easier to quantify into a "gph" reading. Thanks - I'll definately test that method when it comes time to actually give these a go!
