      careful consideration needs to used to prevent too much head created by putting it after the filter and overflowing the filter. Also
      you want to know the optimum flow through the UV and if your gravity return can achieve that.

      It says its recommended flow rate is less than 1200 gph and the largest port is 1 1/2" which is too small
      to try and gravity flow through. If you're going to use that one I'd only put it between the pump and
      filter and plumb a bypass to reduce the flow through the UV.
      I was also thinking of just hooking my current 1100gph adjustable pump to the UV and keeping it separate from the S&G. And letting is dump back into the pond where the S&G pump will eventually grab it. But the bypass in the S&G line is a good idea, I would really need to plan that out as I would like the UV canister in my garage out of the weather for longevity. I'll really have to plan that PVC run.

      My current setup is 1100pgh...3/4" inlet and 2"outlet to pond

      With this S&G. I am going with the 2100 or 2600 gph.... 1 1/4" or 1 1/2" inlet and 3"outlet

      Wouldn't the pump have to work harder with#3, pushing the water up through the gravel and up the barrel. Compared to #2, gravity would take over once water makes it over the top of the barrel.

      No...
      because the inlet pipe extends to the bottom of the media causing the water to rise through the media either way.
      But the benefit between 2 and 3 is only the difference in the height of the incoming pipe in #2 and the lowest point
      of the output back to the pond from the filter, which is only a few inches. I've got s/g filters built like both #2 and #3
      and they both work great.

      Just finishing our new pond, we built 3 of the Birdman type sand filters and they work great. went from a muddy looking pond right after construction to a crystal clear pond in 5 days. The pond is between 55 and 60 thousand gallons
