Red Sea Doser 4 Bought the doser when it first released from a local LFS. Used it for a month or so and then sold my tank and the new tank I have does not need to be dosed. Let me know if you have any questions. Does not come with tubing. Also, there might be a little calcium in one tube. Can be ran through ro to clean.
