Hi! I just recently bought (2) 55 gal tanks and I want to start a couple reef tanks. I've been researching a lot and have decided to just do 1 at a time til I get the hang of it. My first question is can you run 2 tanks off of 1 filter tank? My second question is about lighting. iI've read that I need about 10k Kelvin and 7-8 watts per gallon lighting for hard coral and soft coral requires a more yellow light. Can I run a soft coral tank with the same lighting as the hard coral or will this hurt the soft? Thanks in advance for any help!
