UV question

[fab]

Flow rate and exposure level are inversely related.

High exposure levels obviously require slower flow levels. In the extreme cases, with zero flow the UV exposure level would increase to enormous amounts as time matched on, whereas at extremely high flow rates There would be barely any time for the exposure to occupe.

This just a simple case of inverse relationships.

I understand that, but what is considered "slow flow". I have a 260 GPH currently and originally had it set to the lowest flow rate, which was barely a trickle. According to that article, it states 8-12 gph per watt for parasite control. That's a minimum of 456 gph.
