I just got my Cade 1800 s2 set up and running (Day 4). I have a lot to learn as I am new to the hobby. I am running Hydros controllers, and reef Octopus pumps and skimmer. I made the mistake of trying to run a separate pump to run the UV and it was pushing water through the main pump. So now I have a Varios 4 that will be un-used and just did a closed loop off the main pump. Any feedback would be great.
