Return pump and UV switching flow

[EvilLucky6]

Food for thought .
2 return dc pumps ecotech L2
2 UV sterilizers 80watt
Both are the same.
Now what about switching the flow rate back and forth to help with Random flow
Algae & bacteria Left return 2700gph
Protozoa Right return 450gph
Run for 2hour like that next 2hours
Algae & bacteria Right return 2700gph
Protozoa Left return 450gph.
In theory I think it would work.

hi,only concern would be,overheating uv at 450gph for two hours?? what is recommended min flow for your uv??

That is the flow rate specs per Pentair Aquatics

I would not think you would get 2700 GPH thru the UV with the L2.

I run my 90 watt UV right around 500 GPH 24/7 with no issues. It’s been on line for a year and half. I clean quartz tube every six months. Replaced lamp after one year.
