You're not ordering what is pictured
What you are getting is 8 chlorine tablets. With these you have to pry the existing bottom open of the Flushmaster plastic container and refill it. Good luck on that, I've been down that miserable roadand it isn't fun. It isn't designed to be refilled. The existing container comes with 3 chlorine tablets in it. You are not "refilling" the container. The seller wants you just to put one chlorine tablet in it for the refill. Instead of having 8 full refills, according to his instructions, you really only have 2 2/3. If you still want to go this way Amazon sells these much cheaper ingredients a larger plastic bottle.
