Exactly...you need a par meter, rely on manufacturers data, or alot of popular fixtures have had test results done by individuals.There's alot of formulas I've found to convert lumens to par, but they are not fit the aquarium of you know what I mean lol, it's a very complex thing to do which I don't really understand lol, so here's the thing, from what I'm understanding is it's really not lumens it's the rating of Nm, the redd are 630 Nm but should be 660 Nm blues are 445 should be 475 etc etc, I know nothing about light but there are formulas to convert by I haven't found one for led.
Anyway...wouldn't loose sleep over diatoms. Like snails to me its a good thing. Tank is maturing.
