Can anyone recommend a good dwc bubbler?

Can anyone recommend a good dwc bubbler for an 8 watt hydro air pump? Ive looked all over amazon and cant find anything.

chekc out petsmart, petco walmart etc. buy extra since they will clog up over time

and while you are shopping buy an extra air pump too. sucks when they stop working and you don't have a spare. lol.

i like these, they're about the size of a golf ball, put out a ton of bubbles, and are heavy enough to stay in place
