My K1 Micro stays on the surface of the water in my Eazypod and will not sink

The K1 Micro when brand new is buoyant and will want to float on the surface of the water. This is perfectly normal. As soon as fish have been added to the pond it takes the K1 Micro approximately 24 to 48 hours to absorb the water and become semibuoyant in the EazyPod.
