I have a tank with a nasty salt creep problem. It is everywhere and it is thick. The tank is empty so what is the best way, and best products to remove the salt creep? I am going to rinse it out multiple times so either fish safe products or other are fine.
vinegar is very fish safe and will get rid of hard water spots and salt creep. it the salt is really thick and your tank is glass, you can get rid of a lot just by gently scraping it off with a razor blade. if you have a ton of time, you can just get the tank wet and wash the salt off with water (it dissolves you know )
