    Reef Octopus kalk mixer...
    Ive got this 2nd hand kalk mixer not too long ago and the pump keeps jamming, have to kick start the pump every single time... Such a pain.

    Any solution? or just change the pump. Any idea how much these pumps are?

    use can use haelia pumps on them, i think its the 6510 not 100% sure, check the impeller, clean the shaft and inner pump where impeller sits, or get a new impeller

    From my own experience, you can interchange them with Hailea pumps. IMO the same pump, just cheaper. Sure others will disagree. Have you washed the impeller in a bit of vinegar to remove deposits..?
    If you have washed / replaced the impeller and it still jams, replace the pump. Problem with kalkstirrers using pumps instead of stirrer "shafts," is that this will happen with the caustic nature of calcium hydroxide and calcification around the impellor. Remember, the movement of the shaft and impellor create amongst other things heat... Ca is less solluble at higher temp.... = precipitation.
    Also, there is likely to be some kalk powder getting caught in there causing issues in the long run.

    Just a question @ZaxXx :

    How do you manually start the pump if its attached to the stirrer?

    open the top... drain out half of the water... stick in a long cable tie. . . not as easy as it sounds lol.
    Opened up the pump again , the impeller is chowed up. Have to get a new one now...
    How much are these? its the pump rated for 500liters
