rosslonghorns Posted February 25, 2009 Share Posted February 25, 2009 I picked up a used Kalk Reactor today, the Precision Marine. It has the quick connects 1/4" on top. The output from the Tunze is a metric size and is just a bit bigger than 1/4" and barely fits in the connect. For those of you that use a Kalk Reactor with your Tunze ATO, how do you connect the output from Tunze ATO pump into the Kalk Reactor? Do you use the stock tubing from Tunze and jam it into the fitting or use some kind of metric to 1/4" reducer? Link to comment Share on other sites More sharing options...
+ACampbell Posted February 25, 2009 Share Posted February 25, 2009 I've used my tunze top off with a kalk reactor. I just jammed the stock tubing in and it never leaked. I think the bigger issue is that the little tunze osmolator is really not powerful enough to use with a kalk reactor. The kalk can create great resistants and you will end up burning out the pump.

caferacermike Posted February 25, 2009 Share Posted February 25, 2009 There is a plain steel shaft in the osmolator that will rust solid in kalk in about 2 months. That's how long the 2 lasted when I attempted to add a small amount of Kalk powder to my make up water. Link to comment Share on other sites More sharing options...
princer7 Posted February 25, 2009 Share Posted February 25, 2009 I use a Reef Fanatic ATO and AquaLifter with my Kalk Reactor. Works well. Link to comment Share on other sites More sharing options...
rosslonghorns Posted February 26, 2009 Author Share Posted February 26, 2009 I will not be adding Kalk directly to my top off water, but the line will feed from top off reservoir into the Kalk Reactor and then into the system, so the Tunze pump will never touch Kalk. But as a result of your comment, I'm now thinking about potential siphon back to the Tunze pump from the Kalk Reactor. I'm guessing I need to put a one way valve between the pump / Kalk Reactor. Do they make ones that fit 1/4 tubing? Link to comment Share on other sites More sharing options...
+ACampbell Posted February 26, 2009 Share Posted February 26, 2009 I had mine set up the same way you are suggesting. It's just kalk can clog up the other lines creating resistance. I recommend using a more powerful pump and selling me your used tunze top off. Link to comment Share on other sites More sharing options...
