Hey guys. i'm a saltwater reefer guy and have been for over 10 years. My sister has a large pond i'm guessing 6k gallons with koi in it. she's got a skimmer box in the pond but the water is still not clear.(has lots of floating gunk) i'm wondering if a saltwater style skimmer would work on a freshwater pond? has anyone tryed this? if they have can you point me to a link or something where this was tried.
Thanks
Troy
