Par readings seem low

I just recently invested in a 510 also. I run a ReefBreeders Photon V2 and I was really surprised how low my par actually was also.

Did some research on the "intensity" settings successful reefers were running and I've been creeping it up weekly by 5% for the last 4 weeks to get close to the par numbers I want (as long as my corals are OK with it).

Sounds like you're in the same boat. You just need to crank them up more.

It's simple, really. If you're running at 60% and your PAR is too low, turn the lights up. Just use the PAR meter and get it where you want it.

You don't need any more lights. You have plenty. You just need to get the PAR where it needs to be. Regardless of what you "think" it should be, the PAR meter doesn't lie.
