light intensity help

[fermentedhiker]

So I'm setting up a SPS dominated standard 29 gallon. The light I have currently is a reef radiance 16" LED. I'm using the tank mount bracket so that puts it about 21" off of the substrate. To get better coverage on the ends of the tank I've removed the optics from the center three rows.

I'm hoping to get some suggestions for a place to start with intensity on the blue and white channels.

What do you guys think?

Not familiar with the fixture, however,
if can you vary the percentage of blue or white (if so coral plus/blue plus T5 specs) would be a good sps wavelength to start. I would think the manufacturer would provide some guidelines, if not and If this as you mention is just 'intensity' (0-100%) I would usually start at the low end (30-40%) and as you acquire sps frags see how they react on the bottom and overtime slowly increase the intensity... you will not 'kill' your sps with too low of intensity only too high, so start slowly... alternatively if you have a access to a par meter and you can get 200 or so on the bottom(make sure measurement properly adjusted for LED) you would be in good shape to start...

Hopefully someone with more experience with your fixture can provide more input for you

Thanks for the reply. It's just one of those standard WiFi programmable Chinese box lights. I'm hoping someone will have some first hand experience with what settings worked for them.
