Salt mix

[Pacman]

Why does my new salt in the pail turn hard after opening for a week or 2. Tx

salt mixes are hygroscopic. basically it will absorb atmospheric moisture if available. once enough water is absorbed, usually calcium carbonate precipitate will form and harden. u can still use it although u may wana check ur alkalinity levels for it.

ummmm.... he just told you the reason why. Well, if you dont understand, let mne rephrase for you. Basically, he was saying, your container either nvr close properly or got hole so the air go inside then the moisture in the air make your salt "wet" then clump together and become hard like a rock loh.
