At the moment running 16K lights which are fine for what I have and my tank has finally got to the stage we’re it is pretty much maintenance free.
I don’t run anything except Skimmer amd don’t add anything except 15-20% water change each week.
At the moment I have softies, however going forward I would like to add SPS/LPS will I need to change the spectrum, which is predominantly Blues, UV as opposed to Red, Yellow.? Most of my softies are on the sand bed or no higher than halfway up my tank and do well
I tend to run into algae issues once it goes to the 12K mark. So not really prepared to lower this of it means my tank starts having problems and I have to add things again like GFO or NoPox etc
If someone could advise what they are growing and what conditions K wise
How long he light period is ramp up/ down plus anything colour wise they have increased or decreased I would appreciate it .
I run 2 Radion X -15s at the moment in 3 1/2 by 2x2 tank
