DIY Sand Cement Aquarium Cave
Make a cave for your aquarium fish or eels! Mix play sand and cement into a dough. Form the dough into a platter, place a plastic pipe onto the dough platter and form the remaining dough around the pipe. Consider decorating the cave with plastic plants and allow the cement to dry. Soak the cement cave in a bucket of water, changing the water daily to remove any chemicals from the cement, and place the cave in your tank.
