Works well, but tedious installation
on March 20, 2016
I've been able to decrease significantly the amount of chlorine I use in my spa since I've added the Nature2 Spa Stick. It almost caused a disaster, though, when I dropped it into the stand tube/pipe in my filter. The instructions aren't completely clear, and the stick went all the way down into my filter beyond where I could see or reach it. I had to fish it out with a bent coat hanger and some other MacGyvering, a process which took almost 4 hours. Since this doesn't fit in my spa, I have to use a zip-tie to attach it inside the filter.
