I love the side angle photo. It shows the depth nicely.
Does your wood and sand develop GDA coating over time? How do you go about keeping them as tidy as possible?
I am about to transition my high tech stem plants setup to a low maintenance setup with lava rock, spider wood and slow growing plants. Livestock too will be very similar to yours.

Only algae i've seen so far is the usual biofilm on the glass, GDA on the rocks/sand and some BBA on older leaves/moss.
When doing the weekly waterchange I try to waft out any detritus from the rocks/plants and stir the sand while siphoning everything bad out. I do 50%+ waterchanges and if you keep up with them you shouldn't have any big problems. You'll always have some small sort of algae in the end, it's all natural.
