kent sea salt
 

I have just recently bought kent sea salt. Does any one know how much to add?? ie 1 cup of kent sea salt would treat how many gallons??? I think it's one cup per 2 gallons not sure though.

1 cup to two gallons is a good starting point. Then you need to measure it.
BTW, you know you posted this in the buy/sell/trade forum, right?

oh oops
