My kessil sits 6" off the water with with a depth of 18". It is running 55% on the colour knob and about 65% percent on the intensity knob. Once I get a cord for the Apex I will come back with better numbers. I may turn it up as I go.
But at the moment I am more interested in what PAR numbers are doing around the various corals. I picked up the par meter unit for the apex and have started to log brightness on the various corals. A few observations so far:
Meteor Shower par 120 under AI badly faded, now under Kessil at 80 starting to look happier after a week. Ive read these guys are good at about 50 par.
Superman chalice really happy at 120 par.
Mycedium Elephantotus not happy at 125 par now at 95 under Kessil.
Pink Pocillipora up around 300 par under a Evergrow 120 is happy and has great colour. It is maybe being pushed a little too hard? Likewise the green slimer and Hawkins nearby.
The Riddler is in a shadier spot at about 55 par and seems about right.
I suspect these numbers will change and evolve as I figure things out.
