Hey guys so I recently set up a frag tank which is 15Wx24Lx8H inches. The distance between the light and the corals is about 20in. I have the xr15 set in the middle with the diffuser. It currently is running the ab+ program with a few changes : to follow my main tank lighting scheme. Basically I run the program at 70% intensity which then means I run 43%intensity for my all Blue time period and then it goes to 50% intensity from 1-6pm. I am wondering if I should give the light more power to make sure I am getting enough light to these corals. I run black boxes at 100% so i am not sure how much par these radions can pump out compared to the blackboxes. I do have a seneye I used but the readings seemed rather low for the radions like 100-200 par with this current set up. I do have another radion but would rather keep it as a spare but will put it on if it would be beneficial. Any help would be appreciated.
