I don't use salt in my small aquarium as I found it effected my moss balls and they are too precious to risk. IMO The oxygen/carbon dioxide/ammonia benefits of using the moss balls far out weighs any benefit the salt would give especially in small tanks.

I did use to use salt in my big tank if my fish seemed out of sorts and it did seem to do the job and I was happier doing that than using a lot of the 'cures' that were sold 10/20 years ago. If I had thought about it I would have used it in a hospitalisation tank this time but the fish that died all looked 100% OK before they died and never showed any signs of illness or stress.

Do you have any live plants in your aquariums Graham and if so what types?
