at 30,000 µw/cm2 (EOL) GPH: 2,900 (Max Flow Rate)
at 45,000 µw/cm2 (EOL) GPH: 1,930
at 60,000 µw/cm2 (EOL) GPH: 1,450
at 75,000 µw/cm2 (EOL) GPH: 1,160
at 90,000 µw/cm2 (EOL) GPH: 967 (Min Flow Rate)

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.

(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).
