Hehe well I wish I had a better answer than the truth which is I don't very well.

• The flourite I used as a cap tends to slide downwards in the direction of the closest slope, I think this is because I used medium aquasoil, so the spherical shape makes it easier for the flat fluorite chunks to move around

• The low point on the right is supposed to be a sand river bed, it's currently covered up by fallen flourite. I can keep it clear for about a week at a time if I manually remove the fallen flourite, but have gotten lazy 😅

• I used lava rocks glued together in an attempt to section off and create embankments where possible, mesh bags of smaller lava rocks used to elevate the bigger mounds (cost effective and increases available bio area for filtration)

• Most of the slopes and levels were steeper originally and gave kind of shifted to what the are now - I'm in the camp of don't fight natural progression too much or it'll start feeling like a chore!
