My concern with the 350 is the flow rate. It's rated at 350gph. And while i'm sure real-world flow isn't quite that high, i did plan on keeping media on the light/sparse side in the filter i'm using for the UV. I want the water to stay in the UV as long as possible. So maybe the flow would be significantly more than say, 200 gph? I'm not sure...
Since i'm taking my time with this setup, I just want everything copacetic. :grinno:
I used my 350 w/micron to push water through my Pentair 15w UV. The Mag 350s flow was too low. I had to change it out.
I am a large proponent of the Mag 350 w/micron for water polishing, but the micron sleeve really reduces the flow.
You may be interested in putting the UV on the output of the 2028.
