Like the title says, I just switched from 48" Current USA Orbit Marine LED I've been running for a few years to 3x VIPARSPECTRA 165W Black Box units mounted lengthwise across my 60" 100 gallon tank, about 10 inches above the water's surface. I paid a little more than the ebay price just to have Amazon's customer service and free returns so I want to get these things dialed in and working well in the 30 days I have to work with.
The tank is still pretty sparsely populated as far as corals, I've just been dipping my toe into the reef part (tank had been FOWLR for years) so I've only got 1 duncan, 1 pink nepthea, 1 torch and 2 zoas. I threw together temporary mounting using PVC last night and set a basic 8am to 8pm schedule with the whites at 10% intensity and the blues at 15% intensity.
Anyway, I'm unsure what I should be doing with the lighting intensity. Running them at 10% and 15% looks a fair bit brighter and the spread is way better, lighting up a lot of cleaning of the glass that I need to do that was hidden by the Orbit Marine. I've read some comments about people bleaching corals and causing other damage. The instructions that came with the lights say to start at 30%. I did also pick up a Luxmeter with the lights, so that may help, but i have no idea how to use it yet. The math probably doesn't work this way, but napkin math based on the specs says Orbit Marine is 46W and these are 165W x 3 so 495W so 10% intensity on the new lights should ballpark equal the old ones?
Also, how quickly can/should I increase the intensity? How high should I eventually bring it up to?
