Ok here I go, I have a brand new 40 gal freshwater tank. I got some conditioning salts too and the only directions I got on the bag is that 1 level teaspoon for every gallon (4.5 litres) of water, 1 level tablespoon for every gallon (13.5 litres) of water. I feel dumb now but does this mean that I have to put 40 tablespoon into the water??? Isn't that too much?
