UV sterilizer

Going to place and order and seeing if I need to go bigger on my pump or it’s good enough size to kill off the bad stuff.

Thanks

For the 25 watt classic this is the specs, so target these flow rates with what your objective is. You also need to calculate your plumbing head losses as well when choosing your pump size. IMO the pump you picked is way undersized for this UV.

Recommended Flow Rate for UV Dosages
at 30,000 µw/cm2 (EOL) GPH: 1,200 (Max Flow Rate)
at 45,000 µw/cm2 (EOL) GPH: 800
at 60,000 µw/cm2 (EOL) GPH: 600
at 75,000 µw/cm2 (EOL) GPH: 480
at 90,000 µw/cm2 (EOL) GPH: 400 (Min Flow Rate)

Information for Reef Tanks
A UV rated in the 30,000 or 45,000 µw/cm2 (EOL) is ideal for the reef environment. UV’s used at higher kill rates will destroy the planktonic food supply for the reef.

Information for Marine Fish
(No reef or live rock) A UV rated in the 75,000 or 90,000 µw/cm2 (EOL) will be the most effective at controlling fish disease. All UV dosages are calculated at the end of lamp life (14 months).
