Where do you guys plum you UVS?

You mean to run the water from the UV right back into the sump instead of into the aquarium?

Where's your reactor and how is it fed? Most using reactors plum into this loop....

I have mine within a couple feet of the return pumps on the way back to the tank.....

Don't get too caught up on flowrate, it doesn't make as much of a difference as people think. If you actually have enough power for the volume is the important part......

Contact kendragon - see if he'll crunch your numbers - that's the only way to know for sure if UV is doing what you want it to. Anything else is just a silly guess.

I was going to ask this, so is the uv better before or after the sump/reactor?

I just run mine through 2 UV units that is fed from a pump in the sump and the water returns to the sump. This allows a slow bypass of water through the UV units. Works for me but i know others run their return lines through the UV units, but this means shutting the whole tank down when it is time to change the bulbs over.

Sorry I don't use a uv but nice to see you back

I like your way of thinking Jim, not interfering with the main flow on the setup every time you have to change bulbs, I'll remember to plumb my UVs this way when it's eventually time to do the filtration on my pond 😃

It saves having to shut the main pump or pumps down and the UV treated water is still going to get circulated back to the main tank anyway so no issues.
