Hi could anyone tell me if they have also experienced a hardening and cracking of plastic bottles that have been filled with Seachem Kalkwasser? I have been filling 12 2L Coke bottles with Kalwasser and RO to fill my ATO system. I recently found that the bottom of one bottle was cracked but put it down as just a broken bottle. Today I noticed that most of the bottles are cracked at the bottom and very brittle. Now I am worried about the plastic container that holds 20L for my ATO pump. Has anyone experienced anything like this? If I use a glass tank for the ATO will the concentrated KW affect the silicon glue? Any comments will be gladly appreciated.
