Could someone advise what would constitute low/mid/high par levels for led lights at the substrate?
I would also assume that par levels at the substrate is what's important. It does not matter the par level at the top of the water levels where some drift wood branches could be with moss and mini pellia? I notice that even in a 18" deep tank, the difference in par levels at the top and bottom is insane! It's anywhere fr 3-5 times difference. Just wonder if I may need to make any landscape changed as a whole bunch of my mini pellia is at the middle to top of my tank in this case.
I recalled somewhere that Tom said to aim for 30-50 par levels at the substrate. I got confused as people seem to be recommending different par levels for t5 and led. Not sure why there could be a difference?
