If you are looking for this diffuser on a base, which you can weight and put in the pond to connect to your weighted airline, you are looking for an MDB11.

The recommended flow for this Matala diffuser is 25-80 lpm. The Alita AL-15A can only output 20 lpm. Likely this will cause issues with the pump as well as a less than desirable bubble output. I suggest looking into airstone diffusers around 9" or rubber diffusers closer to 6".

The bottom inlet is a 3/4" male pattern thread. If you need more help you can call Pond & Garden Depot toll free at 1-866-305-5459 Cody H. Customer Service **Q: Can this disk handle a hiblow hp-80 pond aerator** A: Hello, Thanks for the question! Yes the 9" disc pad will be able to handle up to 80LPM. You may want to look at the following link of the MDB!! which would be the diffuser base and pad. https://www.amazon.com/dp/B01MTJOEK4?ref=myi_title_dp I hope this is helpful!
