I've started increasing epsom salt and using metro for fish that stopped eating. I use epsom as a buffer, normally 4 tbsp. per 30 gal with water changes, but increased the amount to 2 tbsp. per 10 gals. When the treatment is complete what is the best way to lower the amount of salt and get back to my normal numbers. I was going to cut the amount of salt in half with each water change til I'm back to normal. Is that ok or can I just do the next wc as normal. Don't want to shock the fish.
