Hi everyone! New to the forum. I’ve kept salt tanks since age 13 till 27, now getting back in it at 47 lol. Starting a 20 long and just purchased an AI prime 16hd on backorder. Question is will this be enough light to grow a new reef? Have a donated aquaclear 50 filter and was advised by LFS to not use the media it came with. Haven’t bought substrate yet, crossing that bridge when I get there
