I installed this on an old popcorn container that I had and I got it all setup on a slow drip. It was easy to put together, only took about 10 minutes to assemble and it seems to be holding my calcium and alkalinity steady. I still dose magnesium to help maintain the CA & Ak. Much cheaper to use than the ready made units, which is important when you have a tight budget.
