It's definitely some kind of ugly when the sand first comes out. Still trying to get used to the look of it, but I'm sure it'll look better when the coraline starts. Super cool how I can direct flow anywhere I like now. For that reason alone I think I'd find it difficult to put the sand back in.
I'm having a lot of trouble getting the last bit of sand out from between the rocks, and the sand has caked along where the rock meets the glass so it has to be chipped out. So for the next little while it looks like I'll be blasting with a power head and siphoning
