I've been prodding the substrate of my soon to be shrimpery every day since I set it up and wherever I prod I hit a gas pocket. I've got John Innes no 3 topped with fine black aquarium gravel. Obviously when the shrimp go in don't want to be doing that everyday, it'll stress the shrimp. How long is it safe to leave?
Anyone got any suggestions other than redoing the bloody tank again!
