So I hadn’t read this till now and just did my rockwork last night. Go figure lol. I had put the sand in the bottom then the rock. Is it worth it at this point to siphon out the 1-1/2” of sand, take out the rock, put something else down then put everything back with sand around the rock instead of under it? I had scaled back on the sand under the rock so that it was only about ½ to ¾” deep. I plan on eventually siphoning out down to that level once the cycle gets going but wanted some extra sand in there to start.
Thoughts?
