Friends.. quick check.. I want to make sure I am calculating this correctly and make sure I have adequate lighting.. want to keep my LFS honest as well.

My current lighting system (going live soon I hope) has 4 Coralife 10k daylight bulbs - High output T5 - 54 watts (48in)

to figure out the WPG I assume I take 54x4 and divide by 75 (size of my tank)
Getting 2.88 WPG..

Is that correct?

Can I assume that should be plenty of light for growing my plants?

Light is approx 21- 22 inc from substrate

Thanks for your help and putting up with all my questions

WPG is for T12 bulbs. With that setup you will have very high light.
