A little rigid airline and a hot air Gina md you can custom fit pieces to fry bowl lips or over aquarium frames. Works great for keeping airstones in place to aerate incubating eggs or fry. Works great as part of the #airstonefryfilter for water changes. Add a plastic inline air valve for fine control of air right at the bowl. #aquaculture #ranchurancher #goldfishbreeder #goldfish #goldfishpond #goldfishunion #goldfishgarage #goldfishjunkie
