My quark is what are you talking about when you say lower PAR? Are you saying 100, 200, 300? What did lower PAR mean to you? Do you actually know your PAR or are we just saying lower in the tank? If we are just saying lower in the tank what lights are you running on what size tank?
Also, have you considered Montipora?
There are some really nice variants that do great under 200 PAR.
That Kung Pao in the bottom of the pic is only at around 150par.
