You put a little on the white impeller shaft? I guess this is safe for the life in the tank?
I ask because I’m pretty meticulous about cleaning mine in citric acid. But I’m sure there’s no longer lube on it at this point.

I have two mp40’s and they’re FINE. It’s like having that car that it works perfect but there is nothing to enjoy. That said. I just purchased an ORCA and…. Yeah. It’s worth the bang for the buck.

@serval sorry im going to split off reply to get rid of the weird amazon associate thing.
I just toss a dime size dab right on the base of the magnet where it slides over the shaft. It lubes the shaft a bit and lubes the magnet and forms a little barrier to keep tiny snails and such out. Its food grade and ive never had an issue with it even when a little gets into the tank ive watched my tangs try and take bites of it.

Wow. You’d think for that much they’d be “water proof” and not rust since ya know that’s the whole point

Yeah I’m looking at the jebaos. As of now I don’t really care about the wires as I can just get cheaper ones and then down the line maybe upgrade to mp40s for cleaner look. Can save the money and use it for other things. A power head is a power head as long as it moved water. I think their main selling point is the app and wires but whats difference in using app and controller if your right there. Unless your not home
worth the price? Not full retail.
However they move a lot of water. If you go that direction, definitely purchase a spare wet side (i know, it’s expensive) to swap out when they get dirty. Less wear on them and worry.
people saying it will rust is an outlier. That’s why you keep an extra wet side ready to go every week or 2.
I’ve had mp10s and mp40s. They last a long time, no rust, no split magnet. I clean them when needed in citric acid. I’ve sold the 10s when I needed the 40. I have replacement wet sides to switch out when cleaning. The only pumps I’ve ran in the DT for years.
how long do you soak in citric?

I've got 4x MP40s that I bought new when I set the system up as I wanted to try and get 'the best' where I could afford to for this tank and honestly for the price (around $800-ish AUD each when not on sale currently), I don't consider them anything amazing and wouldn't necessarily recommend them or rush to purchase them again. Since owning I've often wondered how they've become so revered in the hobby to demand such a price tag.
Yes, they can certainly move a lot of water, but unless you have a lot of SPS, need to move some serious water (ie. from one end of a peninsula to another), really value the use of the app for some reason or can pick it up cheap I wouldn't bother.
I've personally found them a bit frustrating in that especially when new or have just been cleaned the fan shields like to spin themselves off leaving the fan open to potentially mince or slice any fish that happened to get close enough. It was so bad early on I had to use a couple drops of coral glue to try secure them and stop it from happening. Even now, 2.5 years on, if I do a thorough clean it's almost certain 1-2 of them still unwind themselves within the following couple of days and need to be fitted again (despite ensuring they've been seated and twisted in properly).
I've also had random issues where after repositioning after a clean, it takes several attempts/twists or whatever of the wet side to try and get the magnets to re-align properly with the dry side for the fan to start up again. This has to be done when the unit is off too because if you align it incorrectly when it's on (or happen to bump it to misalign it enough during cleaning the glass) the dry side likes to vibrate and bash/bounce against the glass.
For a bit of a TLDR List;
Pros:
- Capable of moving a lot of water and providing strong flow
- App is easy to use and offers a few different flow options, including scheduled flow changes or even pairing of units so that they work in tandem with one another to create different flow types.
- Easy to pull apart and put back together to thoroughly clean without having to remove wires.
- Offers replaceable parts (ie. wet side)
Cons:
- Overinflated pricing
- Parts are overpriced (looked at getting extension cables so I could put controllers all in the cabinet on one side, and they wanted to charge a ridiculous amount for it, somewhere around $200 AUD each for memory). Even the wet side can cost as much as a full pump set up from Jebao or whatever.
- Shield can spin itself off, even when it has been seated properly.
- Dry side will bounce itself against glass if you happen to knock it enough that the magnets misalign (ie. when cleaning the glass) whilst operational.
