How to plumb a UV Sterilizer... according to Ryan...?

[salty150]

What is the "acceptable" way (according to Ryan) of plumbing a UV sterilizer from the sump back into the sump.

According to his UV YouTube video - you really shouldn't plumb a UV that way (from sump to sump) - but he states that "with enough thought there certainly is an acceptable way"...

But then doesn't say what it is.

I would guess that you need to pull water from the first chamber and supply back to the second or last chamber. If you supply off a manifold from return pump and put it back into the sump, then you are ( to an extent ) just sterilizing the same water over and over again.

That would be my "guess"...

Pull the water right after it has been filtered by the filter socks/roller - and then dump it into the very next chamber so it doesn't bypass any filtration and doesn't get re-sterilized...?

Exactly right. The goal is to not bypass any filtration and to minimize the water being immediately run back through the sterilizer. The way you've laid out in your diagram would work and avoid both of the afore mentioned issues.
