Cracked Red Sea Reef Dose

[Billgasser]

I noticed my Kalk was leaking and found my doser on my Red Sea 4 doser had a crack in it. Has anyone had this same issue ? I have only been using it for a little over a year. Luckily I was only using 3 or the 4 and was able to place the Kalk on the empty doser. I attached a picture and you can see the cracks are at 12 , 3 , 7 and 11 on a clock. It has not been dropped or hit with anything.

Looks like impact damage to me. I've had a reefdose 2 running for almost 3 years but never dosed kalk. I always figured kalk would plug the small tubing. I used a brs doser and 1/4" ro tubing for kalk.

I don't know if it's possible but back in 2013 I would use my ATO container to dose Kalk and it was your standard 5 gallon "water change" container everyone has. After a couple years of use I went to pick it up from the handle and the whole thing split horizontally in the middle. It had become so brittle even though it was kept in a dark cool closet.

I would think impact also but unless something happens when I’m not around don’t think that is it. The entire doser is attached to the wall of my cabinet which holds my sump. I do run a super saturated Kalk.
