This addition helped to improve water quality by acting as a buffer and our sting rays love to bury and forage for food in it. At that time a flow- through platform was installed to keep the sand from getting sucked into to a large filter return located on the bottom. The original platform was not sturdy enough and began to fail, so it was removed and temporarily replaced with a ring of sandbags used to keep the bottom substrate from the filters. This new structure will restore the original plan for the exhibit, and allow the animals to fully enjoy their habitat!
