We've had an intex SWG with great results for the past 3 years or so. This year ours wasn't working and I ordered a new one off amazon. So far it doesn't seem to be working and I'm not sure if it's this particular SWG or something diff with the new ones they are making. I ran it yesterday for 10 hrs and only have .5 chlorine levels. The pool is clear with no signs of algae and we've had the cover on the whole time. The old one I used to run for 3-4 hrs and would have no problems keeping chlorine leveled where they should be.
This is the model we just bought.

We are leaving for a camping trip now but my plan is to return it after we get back but wanted to check here for help first.
