Using the Penn - Plax Deluxe Bubble Disk is easy. First, connect it to your air pump using standard 3/16 - Inch tubing (you'll need to get the tubing separately). Then, place it in your aquarium at any angle you like. You can even bury it under the gravel if you want to hide it. When it comes to maintenance, occasionally check the disk for any blockages. If it gets dirty, simply take it out of the tank and rinse it gently with clean water. Keep in mind that the air pump and tubing are not included, so you'll need to purchase them separately. Also, make sure to follow the safety instructions for your air pump to ensure proper operation.
