That doesn't inlclude the two titanium heaters I bought from another place. You will also need salt, a test kit some LR/base rock. I ordered the above from drsfosterandsmith.com, they don't charge for weight, my shipping for all that was $15.99. Keep in mind, those do not have to be specific to your tank, you can swap them out with other porducts. You will probably want some timers and a UPS as well.
