Hello, I have a maxijet pump that turns on, but the propeller doesn't spin or move any water. I can hear the pump turn on. Any ideas would be appreciated. ------------- Here is what a customer said while on hold Oh my gosh! Did you open the door? I told you not to open the door.

The impeller could be clogged with scum. If it is clean, heat might have caused the impeller to expand, causing too much friction for it to move. If the impeller seems perfectly fine, then the magnetic coil might be damaged inside the pump. I would take it apart, clean it, and go from there. ------------- 125g 90g 2x33g 34g What stores do I recommend?

+1 ^^^ They get mulm build up on the impeller shaft that restricts flow into the impeller socket and then they start to heat up. Once they get too warm the plastic bulges and touches the impeller so that it wont spin. Clean it all up good in some vinegar and water and if it doesnt turn after that it's probably time to replace it.

Oh... It's called mulm. Yet another thing I've learned from old man Krazie. ------------- 125g 90g 2x33g 34g What stores do I recommend? Up North: Bill ( Saltwater Paradise 801-317-8115 ) Down South: Jerry ( Reef On 801-563-0600 ) Member of GCFB |

Yup. If you end up with mulm on your LED lights then you have a much more serious problem!  ------------- My ocean. 90g (yup, won it!), 40g, 28g, & 10g Systems PADI Advanced Open Water http://utahreefs.com/forum/forum_posts.asp?TID=63568&title=krazies-nano-paradise" rel="nofollow - Tank Thread: |

You'll end up with mulm on your face if you're not careful. ------------- 125g 90g 2x33g 34g What stores do I recommend? Up North: Bill ( Saltwater Paradise 801-317-8115 ) Down South: Jerry ( Reef On 801-563-0600 ) Member of GCFB |

It's happened before, will probably happen again. Those impellers get slippery! ------------- My ocean. 90g (yup, won it!), 40g, 28g, & 10g Systems PADI Advanced Open Water http://utahreefs.com/forum/forum_posts.asp?TID=63568&title=krazies-nano-paradise" rel="nofollow - Tank Thread: |

Check and see if the impeller part and magnet part are still connected. I've had them break so the magnet spins just fine but the impeller blades don't. A little super glue will get you working again if this is the problem. ------------- 150 gal reef with 50 gal sump. Reef Octopus DCS-200 Skimmer. AI Sol Blues. |

+1 DMower I have had now 2 maxijet 1200 break the little tab that keeps the magnet and impeller blades spinning together, ifbthat breaks off and then viola no more water flow. I think it has happened to me twice now as it's the pump I use to run my dual reactor and the back pressure after a short time takes its toll. Super glue fixed it right up. ------------- 90 gal reef w/refugium 24 gal softie tank 11 gal nano anemone tank 5 gal fresh water |

I agree. The fix is to superglue the magnet to the impeller shaft. I have more of those impellers if the fix doesn't last. Aloha  ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member
