Aqua One Airstones
It's essential to use the correct Aqua One Limewood Wooden Airstones in your Marisys Filter as cheaper non-brand airstones tend to swell up and can become extremely difficult to remove from the chamber. Using official Aqua One airstones guarantees the very best, hassle free performance from your skimmer.
