I had 2 AI Prime 16 HD on my 75 gallons, 48 inch wide and 21 deep tank. I have LPS and softies. I had the intensity set at 90% and everyone was doing fine.
Then I added 2 more AI Prime 16 HD, to eventually get into SPS also. I set the lights as 2 separate duos and have them both at 55% intensity right now.
Here is my question : without a par meter, what is the best guestimate for intensity so that it is close to the 90% I had before ?
Thanks !
