I currently have 2x250w megachrome marine 12.5k On a 125g 24"high . I have some blue acros. which I thought should be bluer I'm woundering if I need to upgrade to 400w or do you think I'm getting enough par on the 250's to keep some light loving Acros. The fixture is located approx. 9" from the water.
They are on for 9hr a day.
Wow thats intresting on the par of Ushios and the Coral.
Thanks!
