Hello
This topic and subject is so opinionated it’s scary. What’s worse is everyone is in theory correct, they have produced amazing tanks. For example I my tank had done amazing with acros and I use current marine pros model 4117 and my tank is a 240 which is 72 long 34 tall and 24 deep. My lights are super strong and easily reach the sand bed.
Yet people have used kessill radions Chinese black boxes etc. people have used metal h they have used t5 they have mixed them who knows. But here is probably the most important part, which is you, yourself must like how the tank and lights work for you. I can’t get the same color and growth from another light so I keep them. But corals adapt to their lights so do not change stick with what you get.
I have seen beautiful tanks done by all lighting and they all are good options. People always say you get what you paid for, (that is such a lie and not true). There are some lights lots of lights that cost 1/3 of radions etc and easily do the same thing grow coral and make it pretty.
Lights are only a part of the equation when it comes to this hobby. There are many more aspects to it then I have the most expensive lights well I’ll have the nicest tank. So not true. If you want s true challenge use the under dog lights and equipment and produce an amazing tank. Not only does it save you money, but you get a gorgeous reef also. I went with mostly underdog equipment (average ) and I have had amazing success and it saved me lots of money and they have proven to be more reliable than the expensive ones.
Create your own tank and it’s much easier to do that than copy others.
