Reefer_Madness November 11, 2015 November 11, 2015 Note to self: if the output tube coming from the Kalk stirrer sits IN the water, the calcium buildup will eventually plug the tube and backup. The output tube carrying the saturated Kalk should have what they call an "air gap", meaning it should not touch the water in the sump. It needs to drop out of the tube just like doser outputs. One more note self.....shaking the hose to see why the Kalk was backed up was also a bad idea. (5' of backed up Kalk came out of the 3/4" tube, once the calcium plug came out). I should have thought that through a little better......
Origami November 11, 2015 November 11, 2015 Even with an airgap, you'll get deposits. I routinely have to clear deposits from the end of a 1/2" tube coming out of my kalk stirrer. It's possible that it may accumulate more quickly if the end is submerged, though.
Origami November 11, 2015 November 11, 2015 I had a calcium snowball on the end. Should have taken a picture. The build up that I got looked like soft chalk lining the tube with a "tongue" of the stuff hanging off of the end. The tube would narrow because of the build up but, because it was both 1/2-inch in diameter, would take a long time to get close to closing off. Further, because it was clear, I could see when it needed servicing.
gmerek2 November 11, 2015 November 11, 2015 Uhg so many variables. Frustrating. Maybe one of these days I'll get it right. Is everything ok?
Reefer_Madness November 11, 2015 Author November 11, 2015 Yeah. All good. My eyes opened up pretty wide tho when it happened. Haha.
