Today there was a happening in the tank. A big bubble of air or gas realesed from the bottom, it was of a size so it splashed water on the light over the tank when it reatched the surface. It also brought some sand in to the water column, i can see sand on some plant leaves. But fortunately there was no cloudyness in the tank water after this.

Is this normal in the start of a soil tank or is it beacuse the sand cap is not letting the soil breathing?
