That is pretty pathetic that they are selling the impeller alone for $40.

Well... As promised here's a new thread with a more complete guide to do this with lots of step by step photos.

Re: retail
Re: retail
Yeah I saw that previously. It looks like a professional job done by a machinist. That said though, his prices are CRAZY. No way would I shell out $60 just for the propeller/impeller and PVC housing.
I have done a few for some fellow RC reefers on here for like $20 shipped. Obviously I'm doing it more for fun than profit but still....

I am so envious of you for having access to a machine shop
All I have to work with is a miter saw, a drill, and a rotary hand tool.
One question I have for you though, how would one be able to make the horizontal slots like the ones at reefdom.com ? Just kinda curious.

Hi all, I'm the guy that makes the mods for Reefdom. I don't tell them what to sell them for, I just make them. I have to get a certain amount of money to make it worth doing(to cover labor, materials, shop overhead like electricity and heat etc) and then they add on what they need for handling and order processing etc. I understand that a DIYer can make a decent mod for short money, but I'm not making these for the DIYer. I make these for hobbiests that can't or don't want to make them for themselves.
So go ahead and blast me, but I get emails constantly, thanking me for making a good quality product that improves their tank flow tremendously.
The slots are made on a Bridgeport milling machine with a 2 axis CNC retrofit.
Thanks, Patrick
What pumps, flow-wise, is this mod supposed to equate to? Just wondering because 1500gph seios complete with assorted mounting brackets and ready to drop in the tank are as low as $65. 2600gph's are $80. How does this $99 mod (pump and bracket included) compare?
(sorry if this was already covered somewhere)
Thanks,
Robb

PHreef, we are not blasting you at all for the concept nor the actual product. I will fully admit that it appears to be an extremely clean proudct. Assuming that it fuctions correctly, I would imagine that I would be interested in purchasing one as well if it were not so expensive.
I think what people here are leading to is that the cost is outweighing the benefit. I understand that the distributer is also adding to the cost, but in just looking at the $40 cost of the impeller, I can purchase all of the necessary parts for the complete MOD, including the MJ, for well under $30. Sure time and tools are needed, but for me to put together the prop assembly doesn't cost me anywhere near $40, more like under $10. Now I obviously don't have any overhead that a machine shop would have, but all in all, they are just really expensive.
I do hope that your time and effort in making these is paying off for you, but I just don't see them taking off in this forum with that kind of price tag.

rburn99, from what I understand, there haven't been any actual studies regarding the actual flow rates between this mod and other products. The only real response we have had is just comparing the two next to each other, and some have stated that, visually, the MJ mod seems to put out more flow than some of the seios. Otherwise, no hard evidence that I know of.

It probably wouldn't be too difficult to stage a test between a Tunze, a SEIO, and a maxi-mod to see and compare.
Anybody wanna donate a Tunze for the test?
Seriously though, all you would need to stage this test would be SEIO's of various sizes, Tunze Stream, and various sized Maxi-mods. Put each inturn in a medium sized tank (say 55g?) with some plastic strips placed on the bottom so that you can visualize the flow and effect thereof.

Actually earlier, I believe it was melev who suggested to use a thin garbage bag, and measure, for a minute (or whatever unit of time) how many gallons the thing filled in that time, and then equate that to hours. I cant wait to get started on mine to give it a shot. As a comparison of course, the plastic pieces would be a decent comparison between each brand of pump, but for quantifying the "gallons per hour" the bag seems more logical.
Like I said earlier, my plan is to mod two of them, one for each of my 30b frag tanks and I plan on measuring the flow. I dont think we can ever quantify it for every mod, because things are going to vary at least slightly between every mod, but it would be nice to compare them.

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 was me.

PHreef, any chance you can enlighten us to the make and model impeller you use?

Or you could do a small body of water and just measure 10 seconds then multiply by 360 to get gph.whitesquall said:
