Power AI Prime 16HD

bandando · Aug 13, 2023

Hello everybody.

I have a question about my lamps, two AI Prime 16HD.

My tank is 15,7’ (40 cm) high with a DSB of 4,7’ (12 cm), total 45 gal. , it is two years old.
As you can understand, the water column is very low.

The lamps are 14’ (35 cm) from the water surface.

Predominantly SPS.

What maximum power can I set for not burning them ?

Now I l’m running at 65% V RY B and 25% CW.

Thank you for your advices.

You would need to get an actual PAR reading to know for certain.

As blaxsun says.
It is not very likely that AI Prime HD16 would burn acros outside acclimation period.

A par meter is best.
With that said.
On my 45 frag system, 36x24x12. I run 4 16hds at 10" from the surface. 10" of water so most corals are 6 " from the surface.
I run first 4 channels at 100%.
The rest at 50%.
I have 2 16s on my 30g running the same. A green slimer is touching the surface.
Par is running 250ish 5" down in the 45.
Im getting 200 par in the 30 at a depth of 8".

I don’t have a par meter.

What wrote from @90's reefer is very clear.
First 4 channels at 100% without troubles means that with a good acclimatization I can’t burn my corals if I setting my Prime at 80% or more.

I hoped to read experiences like that.

Thank you
