Where did you get your black sand from? I just went through the same process with black diamond blasting sand from Tractor Supply.
I picked it up from Hamilton Builder Supply for $10 per 55lb bag. Very very dirty, but so pretty.
That bit of wood in the first photo, Is it hollow?, you could hide a small sponge filter in it.
It is hollow-ish. While it is mostly gone, there is a centre part that sticks up almost the whole height. I hope fish use it as a hiding place, but I don't think I will put anything in it; other than maybe some plants.
