Less than I thought. The instructions aren't clear, but I mixed salt with R/O water until 24/25. Unfortunately, my anemone went berserk and I think she's dying now. Arrived the next day. I read the reviews and unlike others the container is in good condition and the salt is packed in a plastic bag. Unfortunately it was only put in the box with my book and other stuff and I was glad it didn't open and ruin my other stuff. It really should be packed with something to protect him and other things from him.
