If size of Pumice rock is big enough (bigger than 15mm), we can easily see them floating over water due to light weight and availability of air cavities inside pumice rocks. But, if we break them into smaller pieces, air cavities of pumice gets filled up with water and find it difficult to float on water. Hence, if we are planning to buy pumice for pond or aquarium, we recommend to use pumice of 3 cm-5cm.
