Check valve for calcium dispenser

[Masoch]

Hi Roger,

Where can I pick up an extra check valve or two for a Tunze Osmolator with calcium dispenser? I bought the setup about six or so months ago (from a Canadian store -- I'm in the Great White North), but the check valve is not ... errr ... checking the flow. This morning, I woke up to find the water in the dispenser at the same level as the water in my bucket.

I had cleaned out the valve a couple weeks ago (it had some calcium deposits) ... and I can see the valve opening and closing, but it just doesn't seem to be sealing.

TIA!

This is probably more important than the check valve- look at all the pictures in the manual and notice the hose is zip tied above the dispenser to prevent this. What happens is without the ziptie the kalk powder hardens the valve so it fails. The check valves from Tetra or most major manufacturers work fine, Hagen is ideal. I do have the replacements but honestly you could just pick one up at any fish store. The only ones to avoid are the RENA or Schego model- too restrictive.
