New Water Cycler Pac Model 407C (For Cycler Series 400 and 600)

I am a long time pool owner that moved to a house with one of these systems in place. I bought a new cartridge and put it in, but even with the chlorine setting on "high" it barely made a noticeable difference in the chlorine level of the pool. It's also a hassle to open up the container that this goes in. However, I do think it helped keep the levels more stable. I still added chlorine in addition to this, but didn't have to add as much.

I have bought this product from my pool place for years but found this substantially cheaper here on Amazon. Great!
