Review: Good tank conditioner - Our go to tonic salt for conditioning the fish tank. Have had no issues with wife's goldfish ever since we started using this product (and tap safe). Wife uses it every water change
Review: Good stuff if you're medicating your fish. - Hi everyone! When I first started keeping fish (in my case, Cherry Barbs), I was a total rookie. After having had fish for some time, I got a problem with fungus. I didn't know then - but I do now - that when medicating, it's a good idea to put tonic salt in the tank as well. Apparently, it helps the medication to work. Since then I've discovered that there's absolutely no harm in adding salt when changing the water. The fish like it, and it seems to be keeping the fungi at bay. This is a good way to buy the salt, a tub lasts for ages! This is only the second on I've had to buy in 2+years.
