I've been looking around grocery stores for pickling lime (calcium hydroxide) and have been unsuccessful. I heard it is used for hardening pickles? In all the grocery stores I've looked in, they don't sell calcium hydroxide to harden pickles but they do have something called "Pickle crisp" , the only ingredient is calcium chloride, so my question is what is the difference between calcium hydroxide and calcium chloride? and can I use the calcium chloride in my tank? thanks
