I am hooking my display and frag tank into the same loop soon, so they'll share the same chemical balance and water. Essentially, my question is what will happen if they have different lighting? I'm running radions on my 120 DT, however don't really want to dish out the money to light an 80 gallon frag tank with radions as well. I'm looking into the reef breeder photon unit. So is it fine to have radions on my DT and a photon on my FT and everything will be fine?
