Hello, yesterday I added 15 ml of aquarium salt to my 20g tank, but today I need to do a 15-20% water change. How much salt should I add back?
Why 50%?Do a 50% water change and add half a dose of salt.
Out of curiosity, why are you adding salt, and what fish do you have in the tank?
Salt should only be added if you are treating a disease or keeping brackish water fishes. Soft water fishes cannot tolerate salt (sodium chloride) for more than a couple of weeks, so if you have tetras, barbs, gouramis, angels, etc, don't treat them for too long.
My guppies have had shimmies before and stopped. Sometimes you don’t find a reason. I personally think sometimes they just get stressed or frightened and shimmy.Agree. You need to pin down the cause for the shimmies and correct the issue. The absence of salt is most assuredly not the cause of shimmies, as mollies are freshwater fish.
If you contact your water supply company (via website or telephone), they should be able to tell you what the pH, GH (general hardness) and KH (carbonate hardness) are. If they can't help you, take a glass full of tap water to the local pet shop and ask them to test the pH and GH for you. Write the results down in numbers when they do the test. And ask them what the test results are in (eg: ppm or dGH or something else).I don’t have anything to measurewater hardness, but my ammonia went up to 0.50 due to the food getting stuck under decorations and gravel not sure if this was the actual cause of my molly wiggling abnormally
