Every time I come here you folks raise my interest in SOMETHING else... this time it's SALT. I see you mentioned the Salt and it being 'weak'.... I bought something called HBH Hermit Crab Salt (it says "with extra calcium") HOW so you know if it has enough salt or not.... It say to add 1 teaspoon to one cup of water... I know I'm not to bright,.. but if the salt water was too 'weak'... couldn't you just add more salt to the water (say 1-1/2 teaspoons to one cup of water..??) Is this supposed to be any good or not..?? I trying to learn??
