I have been using Kent Liquid Reactor for the three months my tank has been up and running. I have added it as my tank needed, so I did not add it automatically everyday. When I went to get my bottle tonight, it had Hardend! There was a little liquid and a hard solid mass at the bottom. I tried shaking, but nothing helped. Now I guess I am in need of a new Calcium and alk
buffer system and wanted to know if this was a good one or if there was something better. I do not want to use Kalk
because I have two small girls and would die if something happened to them. They can get into anything.
