Simply Koi and More Koi

I have a 3500 gallon pond, using an Aquadyne 2.2b ( rated up to 6500 gallons). I can't remember now how many years I've had it .... but it's a brilliant bit of kit.

Thanks for the info Carl ....

Hi all,
Could someone please tell who would stock one of these .... or even who the manufacturer is ?

Thanks.
