Let's say the PAR at the lowest point is 25-30, some slopes(to create depth) achieve around 35-45 PAR, and you have some tall branches or rocks near the light(that I would assume gets near 100 PAR)
I've seen some setups where people attach moss, anubias, and ferns onto the branches as to not leave it bare, but I wonder how they avoid algae problems/stunting/melting when these "slow growing, low light plants" achieve more light than the plants at the bottom. Wouldn't the co2 levels be too low for the amount of light that the plants at the top receive? And even with tall, stem plants that are planted into the substrate, how do the top portions that receive much more light cope with the increased par levels?
And if you did leave the branches or rocks near the top bare, would algae still grow on those surfaces because of all the light?
How does this all work in a non-co2 enriched setup, with different PAR levels throughout the tank?
