so if you take the shroud off you MUST use your hand to hold the impeller magnet inplace and centered otherwise how is it suppose to spin?

I did use my hand to keep it centered. I think that it's off balance when I re-install the shroud causing it to not spin properly.

With the MJMod I found that turning it on and off caused a lot of wear and tear. The prop gets whacked if it starts in reverse. IME the Dumas 3004 prop delivers a lot of torque to that stopper. Like I said earlier I’m using this to produce a strong circular flow in the tank and not a wave motion. I have found that some of the modded MJ’s required a few days to “slime up” and became quiet. Mine is dead silent and that doesn’t change when I do turn it off or on.

Anyone use a mj400 with these?
I run 2 mj900s in a 37g and tried the hydor-flo which oscilated the flow, but cut it down. I might try mj1200s with the hydor-flos, but was wondering what 2 of the mj400s with this mod would do in a 37g tank?

man im not liking this magnet mount, i have a 3 year old that i know for sure would rip it off the galss given the chance, how could i incorporate using the sureflow setup and no magnets?

You can super glue or epoxy the sure flow bracket to one of the maxi jet mounts.

what magnet mount frezel? Is it the Algae Free one that they sell for the sureflow kit?
The magnets I mentioned are very strong so I highly doubt an adult could easily pick it off the glass without some effort let alone a 3 yr old. |

im not sure what magnets you recommened dhnuguyen, and i was talking about the algae free ones. i just need somethign so that he can rip off and have a powerhead ripping around my tank spashing my acros...I hear these earth magnets are crazy strong
|
#234
|
|||
|
|||
go back to the first page frezel where I referenced some of the ones I've used. They're very strong. You could risk injury infact if you're not careful.

His recommendations are on the first page of this thread. They're cheaper, stronger, and more compact than the algae free version.

Beat me to it. I've got a nice blood blister left over from playing with a couple of these magnets too close together.

there is no way to tell from the vids. I can tell you that they feel about the same as my own medium flow MJ mod which was tested at around 1500gph give or take.
|
#240

|

Eh, either way, I still like them a lot. Very WIDE flow that doesnt hurt my soft stuff. My 1200 still keeps randomly humming though, hopefully that will go away.

who has changed the impeller on the sure flow kit to the dumas? is it worth it (how many gph improvement?) how is it done?
Thanks |

I discuss this on the next page back: http://archive.reefcentral.com/forum...8#post10897728
If you want maximum flow then it is worth it. I just put the impellor from the MJ Mod (with Dumas) into the housing of the SureFlow. HTH Jay

but that doesnt should how to replace the impelller at all, you are using an existing one that you had from the mj mod.

I'm using maxijet 600
Thanks to dhnguyen & luke for their advice.
I have a 125 gallon tank (72x18x23) and purchased two of these kits. Very simple install and very quiet. I was very surprised to see this powerhead push the water from one end of the tank to the other. This is my first experience with high powered powerheads so this is a very big step in flow for me I also ordered the 80lb pull magnets that i am waiting to arrive which i feel is a must have because those suction cups stink. I am running lps/softies and will have to rearrange things to accomodate the added flow. Now i have to look for a wavemaster pro or similar. What do you guys reccomend using? Thanks, Steven |

Hey Steven,
I just ordered 2 of the sure flows as well. I was already running a diy maxi mod and you really need to get creative with placement. For a 125 gal you really shouldn't have too many problems. I have them on a 90 gal (48" long), once the sand has settled to where it wants to be it should be fine. I'm not sure that you can set the duration on the wave master. This looks like it would work: http://www.premiumaquatics.com/Merch...ode=Wavemaking Also this but it has bad reviews: http://www.premiumaquatics.com/Merch...ode=Wavemaking The other option is just to run simple timers on a longer duration. You would just need more of those red/green switches. Vance |

alright im sold! im buying the sureflow kits today , and the 80lb magnets!
have you guys used these strong magnets on acrylic? i am worried of scratches, has anyone put on some felt or something? |
#247
|
|||
|
|||
i have the 80lbs magnets , they are epoxy coated its not going to scratch anything, i have mine on an acrylic tank, the only thing you should be worried about is when you attach the magnet these things are powerful you dont want the magnets to slam on each other then you might have a cracked tank, becareful.
