Reefbreeders Photon V2 24" over 40B

[Oba97]

I have a Photon V2 24" mounted ~10" over my 40 breeder. I am struggling to figure out how high % I should run my lights to allow for SPS towards the top 1/3rd and LPS/softies at the bottom. I don't have access to a PAR meter, so I am looking for advice if my schedule below is probably in the ballpark of where I want to be.

Thanks for your help!

I also use reef breeders. That looks like a good schedule to me.
