Hey folks! I previously had a 26g bow front with sand, and moved within the last year. Started up just a basic 10g with Carib Sea Aragonite 'Seaflor special grade reef sand' with grains anywhere from 1.0 - 2.0 mm in size. It's much bigger than what I'm used to, and I honestly hate the stuff. I miss sand! Is there any sort of safe, non-destructive, and semi-neat way to siphon out all of the substrate and replace it with sand, without tearing the entire tank apart? I was thinking about siphon out the gravel, and slowly lower cups of the sand into the tank once it's been rinsed thoroughly. Any better ideas? I don't want to crash anything by taking away that much lovely bacteria, but not sure what else to do. Heres a pic of the tank too.
