Changing lighting from Kessill A80 to Kessill A160

[kathya0321]

I have currently been using a Kessill A80 Tuna Blue. I am changing to a Kessill A160 Tuna Blue. I have a 16 gal Bio Cube. What is the distance in inches the A160 should be above the tank. I don't want to kill my Corals with 2 much light. Thanks in advance.

I did the same, mine is around 6in from the water surface, I believe around 45% on the a160 is equivalent to 100% on the a80.

45% Intensity? I had my A80 at 8 inches above the tank and peak intensity of 100%,

Not sure what you are saying?

I was just asking if you were saying 45% intensity, and just commenting on what my settings were on my A80 Tuna Blue is all.

I was saying that you get the same intensity with the a160 set to 45% as you do with the a80 set at 100%. So you’ll have plenty of headroom to turn the a160 up, the a80 is only 15watts whereas the a160 is 40w.

I agree, you can start between 40-50% and you should be fine. If you want to increase intensity later on, just increase by 2-5% and wait a week or two and see how your animals respond and go from there until you reach a good place.
