DIY "Stream" Style Pump

The mods I use in my tank are made from MJ 900's. I'd estimate the GPH at 900 to 1000. I've also made them from MJ 1200's for other people and I'd estimate those at 1200+ GPH. Everyone does them a little different (prop size and shape mostly) But I bet most will agree.

Just my opinion, but I think two of these mods made with 1200's will be tons of flow in a 55.
 
the only problem I see with running a wave maker would be getting it to start in the right direction. I know there are a lot of stops and fixes for this, but they are all pretty confusing.
 
Please look at the post I put above, on page 5, I have an awsome system for correcting this, as well as pictures

I remember looking at that. but the close up pic was to blurry to tell what it was. But know the pics aren't working. I will read it again, and look at the pics if they come back up.

Do you suggest using a wavemaker becuase 2 at the same time would be too powerful.
 
Could I get some feedback from long time users of this MaxiJet 1200 Reeftec modifications

1) Has anyone got them working for more than one year and is still using them?

2) Has anyone actually calculate the flow of one of these things.
I think, The proper way to do this is to take a larg empty plastic bag, put it over the outflow of one of these things, turn it one see how much water gets in the back in X seconds, then calculate a flow?
 
I will make sure when I make the next one to take a better pic. Sorry about that. As for the pictures being down. It is because our Network where our server is is currently down. I am the network admin and have been working on that. Just found out there was a power spike at the college and the ISP we use is out for the entire city. It should be back up as soon as they get their techs over there.

Ok I've re-read this thing 2 times today. (2 and a half hours ;)). I understand just about everything. I would just like to know a 'popular' pitch to use. I know to get a 1-3/4" prop, but what is a good pitch?

PHreef, could you PM me with a little more detail on how you machined the parts. My dad has worked in a machine shop for almost 30 years, and I am pretty good with machines. (I ran a milling machine when I was 9:))

I'm not exactly sure where you put the teflon washer. I added it to where i think it goes. Is this right?

Yes thats right. The prop will push that assembly back pretty hard. I've found the teflon washer eliminates the wear problem and helps the prop get going easier. I'll PM you info on the sleeve I've used.

Is there anyway to make this mod work without using a stabilizing rod basically just a prop attached to the magnet the one i made is similarbut it still rattles around a little bit. Any help would be appreciated

IMO, I don't think so. That might work for a while, but the rattle won't stop and the magnet/prop assembly will wear right through the plastic wall of the pump.
 
2 questions.

1. What is a good pitch that everyone is using?
2. Is everyone using a prop with 3/16" hole in the middle?
