So i was just wondering if anyone has opinions on the "Gray Area" of recommended flow rates with regards to protozoa vs algae and bacteria control. I am currently running a Pentair 40 watt uv on my 120 dt. I have it running at around a 200 gph flow for crypto/ich control. Pentair recommends a 157-262 gph flow for this purpose. For Algae and bacterial, the flow is of course much higher at 943-1574 gph. If i run the uv at 400-600 gph, will the impact to either protozoa or algae be nonexistent or will it still affect and sterilize both of them, just not in any noticeable way? I've been wondering about this and would like your opinions.
