Again full of conjectures no actual data proof. I never said you were lying so don't self incriminate. I just need you to show me which test did you do to get the 3000 gph and 12W or 2000 gph at 12W or 2400 gph at ?W.

I already said I don't insist they are impossible but you have to do a little better than just throwing kids talk around in order to convince me.

As I posted previously I am not using those numbers in my portion of this debate so who is skewing the data in their favor? I asked you to provide me a pump that does 1500 gph at 30 watts for under $20 and that was making concessions in both flow and wattage in your favor and I am still waiting.

How do you know your car goes 55? Did you personally do any tests? How do you know your car goes faster then 55? You do any tests? If you did how do I know your tests were conducted properly? How do I know the test devices were accurate? You can use this argument of "non scientific data" or "that test isn't accurate enough" to your benefit as long as you need to defend your skepticism.

Let me bring it down a fraction. Can you look at cars going a certain speed and and tell another car is going faster? The only variable for accuracy is knowing what speed the cars are going to use as bench mark for the speed of the faster car. You can then with a certain degree of accuracy tell if the faster car is going twice as fast or what. I know the flow of my main pump as I stated, and I obviously can tell my MJ mod surpasses it easily. Next comparison. I have a Koralia 4 as I stated in my previous posts, my MJ mod smokes it. I agree "smokes it" is not technical but it is obvious comparing the flow against the known 1200gph of the Koralia my MJ Mod does much more. So again giving you the concession of flow, I state my MJ mods flow at a conservative amount of 1500. I know by looking and comparing it is much more. The Koralia is rated 1200 gph (of course if that is accurate and you can ask them how they tested it). So what more do I need to provide you for you to respond to my original question?

Also Jacmyyoung this is a debate, I am not trying to offend you nor feel offended by you ok? :thumbsup:

Sorry I missed that one but i am totally lost why you asked that? That would be one of the most inefficient prop pumps if I can even find one, what do you try to prove with that?

As far as proof, I never said my test were precise, rather an estimate, and when more other tests done that can agree with mine the more confident I have with my data, which is the case.

Now the 3000 gph @12W (or your 2000 gph @ 12.75W) has yet been even explained, and many other similar MJmod test results contradicted those two claims.

So yes if you what to be absolutely anal about it you can, all I care is to point out the contrast in which both sets of data were presented and verified, and let the readers decide which set is more credible or trustworthy.

Your MJMod can do 2000 gph at 19W if you modded it correctly, you don't need to concede anything except it is not $20 for your average stream pump buyers because they don't have a few MJs laying around and most of them don't care about the DIY work. A full MJMod kit including the pump, ball and magnet holders will cost them $80 to $90 total a piece.

I, being an Information Technology consultant, consider "smokes it" a very technical term, along with "jacked up" and "that thingy".

You just totaly contradicted yourself with this statement because the Koralia then is a terrible investment. It uses more power, at less gph for more purcahse cost then a moded Maxi 900 or 1200 with the 1200 only using more wattage.

Did you check out my occupation? I agree we use "smokes it" all the time when something is superior but I have to be technical here.

I don't see how a K4 doing 1200 gph at 12W can be that much worse than your MJMod doing 2000 gph at 19W? I already said for your average buyer the equivalent parts for MJMod to match the K4 is a $80 to $90 purchase, and the K4 is $49.

If you like to be funny I can try to match that too you know

Are you reading this stuff or glossing over it?

[Rhodesholar]

Wait I think we are talking about two different things. Are you refering to buying the mod? If so I can agree with you there and I don't recall you stating that, but yes that would be cost prohibitive and your side of the debate has total validity. I am saying do it completely DIY. That is my side of the debate that makes it $20 and a better value then the Koralia.

 

[jacmyoung]

Ok then we are even.

$20 will provide you with enough materials for 3 or 4 MJ mods not just one. Just something to consider.

But you're right though... It only makes economic sense for the MJ mods if one was to DIY instead of buying.

That was my arguement all along and I stated as such here.

I am on the other side of the fence. For the money the MJ Mods are hard to beat. My one MJ mod with two props is moving some serious water. I like My Koralia 4 but 49.99 as opposed to roughly $18 for an MJ Mod (doing it all your self) is hard to justify. The problem with the MJ Mod is mounting them.

Actually I have thouhgt about this before, if the MJmods can come up with a completely pre-made unit that looks very nice, with smaller profile and with versatile mount and can do 2400 gph, they can probably sell for $100 easy, maybe even more, as long as it is a plug and play and with good review.

And if the mods can be standardized with some easy third party parts the cost can be cut even lower. When I modded my 6055 and K4, they did not involve any glue and much cutting and trimming, the props and drivers I found plugged into each other perfectly so only minimum labor was needed.

 

[dhnguyen]

Only way to do that effectively and have any kind of consistent build quality would be to use mold injection. This would make the entry cost for manufacturing them quite expensive.

CNC and computer aided design work and initial mold fabrication can be quite costly.

Not sure many DIY'ers would find this feasible to start mass producing these. I know I wouldn't.

$80 is also A LOT to pay for something that most people still consider a mod to an existing product.

Hate to bump the argument...... but my koralias just got in.

Wanted to confirm their power usage in watts.

Koralia 4

My Dart CL (because I wanted to)

 

[carlos_fb]

Can Koralia pumps be plugged to a wavemaker?

 

[johnike]

They click a bit,but I'm getting used to the noise.Have 2 4's on the 180,might get two more!John

 

[Rhodesholar]

Hydor recommends a varible power controller like a Seio as opposed to an on/off controller and I beleive reading somewhere using an on/off controller voids the warranty.

 

[hilgert]

I have seen some of the MJ mods and I prefer the Koralia out-of-the-box simplicity. I did a bag test on the flow rate on my H4's and it seemed like it was about 1200gph (hard to test with a bag, and there is much error when you multiply small numbers into larger ones).

Regarding the wavemakers, I have tried my H4's on the Seio controller and they work fine. The switch is totally silient, no clicking, since the Seio controller changes motor speed and is not an on-off controller like many others. I am not currently running this (just tried it for a day or two), but plan to bring it online soon with an additional one or two H4's in my 210g (so two static H4's, and two on the Seio controller).

The other option I was considering was attaching the two new H4's to Sea Swirls (I have two 3/4" units unused from my previous setup) to get back-and-forth motion. Any thoughts on this?
