So right now I have a 40 gallon IM that I have one sbreef light 16" wifi all the stuff on it. But I want to up grade. Here is my question. 1- I want better colors in my coral, will the switch be worth it? 2- can I get the x15 or should I go right to the 30? And 3- it's over twice the price... Is the price worth it? Thanks in advance
