AQUANEAT Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank (Large up to 60Gal)

Can you add a bubble stone

Does it include airline tubing?

Anyone know where I can find 15mm OD tube to replace the riser pipe with a longer one?

I am using Small up to 10gal version with 1W Bedee air pump in a 3gal water tank. I see the air bubbles, but I am not sure this filter does anything?
