I think I have them up at 70 max currently. I'll bump it up some moreI still have a couple of Reefbreeder fixtures that use a remote. They do make good light (I have an Apex PAR meter).
I'd suggest running the blue at roughly 70 to 90% and the whites at 20 to 40%.
I do a 12 hour day that starts all blue and adds in some white at hour 2. By hour 4 I'm at 80% blue and 30% white and I run that for 6 hours. Then I ramp back down. I have used this over a 90g tank 18" deep) in the past and currently over a 40g aio breeder tank.
How tall is your 40g?I get about 150 PAR at the sand. My 40g aio has a mix of corals and a lot of anemones (5 black widow BTA and 10 RFAs that all reproduce).
