You do not use salt unless your fish has health issues otherwise you run the risk of killing all your fish because their osmoregulatory system is damaged gradually by the presence of salt and even developing diseases such as ich resistant to salt thus salt becomes very much useless by the time you have a real need for it. Why would you add salt in your tank for no valid reason?yourbestfriend;2046039; said:im not talking about treatig ich. im talking about just to use when do weekly water changes. should i still use a tablespoon pure 5 gallons?
This is a myth being repeated. I've pointed out the reason that most FW fish are not used to the presence of salt long-term due to their osmoregulatory system especially for those that thrive in soft, acidic waters. You also run the risk of developing salt-resistant ich and other pathogens thus this is more trouble than it is worth.xFLEAxx;2046209; said:I heard on this site that adding a little bit of salt each time you do a water change keeps all the water levels balanced and is good for the wellbeing of your fish.
