1" Tanks Owners - Jebao, Sicce, Tunze Powerhead Solution

[offshored]

Been going crazy over the last month or so trying to find a solution to hold my Jebao WP40s, WP60s and Sicce Voyager 4000s in place on my new tank made out of 1" acrylic.

The stock magnets are a joke... powerheads just fall right off.

I've tried two different Noedymium magnets with not much success. First had about 90 lbs of pulling force and the second had 140 lbs. While they were improvements over the stock magnets, any slight knock on the powerhead would cause the powerhead to fall.

Finally tried a third. It is a 2x2x1" N48 magnet with over 230 lbs of pulling force.

I was extremely happy to see that the magnet held the WP60 and Voyager 4000 in place firmly. Even if you knocked the powerheads down an inch or two, they'd snap right back into place. Say like a larger fish running into one.

Even gripped on the back of the tank where there is a 1/8" extra piece of black acrylic for the background.

Here is the magnet:

Will probably order the stronger N50 2x2x1" with over 250 lbs of pulling force for the back glass:

Both magnets are pricey in the $28 to $37 dollar range, but well worth it.

Otherwise these powerheads are worthless on thicker tanks.

Hope I saved somebody some headaches and wasted money

BTW: Attached an image of the magnet holding the heavier Sicce Voyager 4000. Will also spray the magnet black and put a thin piece of rubber between the tank and magnet.

or just glue them to magnetic cleaners like algae free

Cleaner magnets might be very price.

Mighty magnet for my tank is 10x more than these magnets

[RAJOD]

Did u try the optional tunze magnet?

Thank for the information, thats not a high price for a large rare earth magnet. My tank cleaner magnet was over 200.00

I would rather have a round one. My wp60 is doing ok on 1.25 inch tank. I agree the magnet is puny but with the suction cup it stays put.

Didn't try the Tunze.

They make round magnets but were out of stock

If I'm seeing your pic correctly you just replaced the outer magnet right?

Yeah just the outer magnet.

[Spazdad]

I took some measurements of the existing 60 magnets. They look to be around 48-49mm x 7-8mm thick. I would like to use Neo on the inside and outside. I figured getting a slightly smaller magnet and coating it for the inside and not for the outside.

Do you think that's feasible. ? It sounds to me that the inner magnet is still an issue and your having to source a much larger magnet for the outside than perhaps 2 medium magnets that fit into the stock location.

[sfsuphysics]

Well if you get a stronger inner magnet then that will make the combined strength stronger yes, not sure if I'd trust any coating I put on the inside magnet unless I made it sufficiently thick at which point you just made the magnet farther away. Also by making the inner magnet stronger you might run into an issue with the magnet interfering with the pump (I seem to recall an issue with the WP40 where if the pump was mounted too close to the inside magnet it didn't work very well).

That said, you can stack magnets to make a stronger magnet. Meaning you could use the included magnet with the WP60 and throw another magnet on the back to get more pull force. You do have to make sure the polarity of the poles aligns right though, for instance the vortech magnet discs north/south are along the direction flat part of the disc I believe, where as these magnets the north south is in the thin direction. Something like the Tunze magnets are two separate magnets aligned in north/south to match up with the Tunze pump so they wouldn't work terribly well for this.

Tunze doesn't have an optional magnet to hold through 1" acrylic....I've already checked that source as well.....

[tkeracer619]

Friendly reminder. These magnets should only be used one at a time. Leaving them out on the table while you are working on this stuff can result in the loss of body parts.

Sorry for the squeemish but this needs to be shown. This came from a guy working with two rare earth magnets. One of the magnets was in his hand, the other a good distance away. It didn't turn out good.

[jjk_reef00]

I was thinking about this same problem for a future upgrade. I'm considering the SeaSwirl Sea Sweep with a Tunze but I haven't looked into the mounting requirements.

[Spazdad]

I've found a few options.

Or

Or



I was first planning on taking out the magnet but it dosent look like there is any shortage of glue holding them in. So I'm going to cut a 2" hole centered on each magnet back and glue one of these in. Most likely the 1/4 on the inside and the 1/2 on the back.

If I need to cap the magnet housing again ill just hack a circle of plastic and ic gel the thing together.

Either way. I'll be able to retain the circle shape and the 2" size is still under the size required to still use the factor housing and rubber spacer retainer.

I'd just buy a new outer and not mess with the inner magnets.

Just paint them back and put them on the back or sides of the tank. They are about the same price as the ones you posted, some are cheaper.

Remember 150lbs didn't even work for me. Ended up with 230+ lb of pull force.

LOL yeah I'm really careful with this things... only one at a time and keep all metal/magnets away from them...

[offshored]

I'll post this here as well, DMed tkeracer619 about this as well.

"I'm planning on putting two magnets (powerheads) on each end of the tank. Some on the back as well...

If one magnet (230lbs) is already in place holding a powerhead in place, should it be safe to put the other magnet (powerhead) on that side of the tank? Or will the new magnet try to fly into the other on that side of the tank, even though the original magnet's pole is already facing and attached to the internal powerheads magnet?

Worried about them trying to stack on each other"

[offshored]

BTW: just tried the dry-side magnet from the WP60 on the side where I have the 230 lb magnet mounted to the WP60.

As I slid close to the 230 lb Noedymium magnet, the WP60 dry-side magnet was just pushed away. Didn't try to flip over or anything crazy.

So I guess it'll be fine with two 230 lb magnets. Not like I want them 6" away from each other or anything.

Thanks for this info unordered some mags I have a 1" thick tank and it a pain to get anything to stick!!

[BrentH]

We'll I bought 2 magnets they work great but must warn u guys my finger looks like the pic above now super painful these magnets are dangerous lol plus I got 2 of them stuck together can't get them apart so used them piggy back on my power head

Damn

Yeah I'm getting nervous about putting 4 on my back glass next.

I'm going to wrap them with electrical tape one layer thick on the front. Then more layers on front and back. Then add some foam tape to the sides and back.

Then add them one at a time. Hopefully that cuts down on flying magnets.

My wife was helping me move a powerhead a few weeks ago and she lifted the magnet 1" off of the glass and the magnet flew down 12" to the stand and made a noise pretty much as loud a gunshot. Took all my force to get the magnet off of the stand.

Needless to say, she didn't help me the rest of the night...

[BrentH]

Ya these magnets are no joke .... It's kinda cool my wife opened the package thinking it was something else and she says all the silverware from the table from about a ft away flew at the magnets lol

Knife drawer?

[Allmost]

have you checked Ching's build ?

he made some sort of holder for tunze pumps, might want to check them out.

The hangers?

Magnets are easier, just need to be careful :x

[BrentH]

Nuxx thanks for the heads up on these there a little pricey but I've spent hours trying to prop up figure out etc.... How to keep power heads and other things on my tank these deff work well and are somewhat small so easy to deal with

I did this many years ago, it worked great. Just make sure you give enough slack for the Tunze cable when the sea swirl moves side to side, otherwise the cable could be damaged.
