I too wrestle with the oxygen airbags when I put newbies into my pond. It's a fun challenge if you're a pond geek
Resist the urge to stock the incoming game fish too soon...sit back and enjoy the fatheads. Forage fish need all the time you can give them. You can learn a lesson now or later...the key to every successful pond is patience. This may be your only chance to fully achieve the potential of your forage base. What else do you have in there ?
