With regard to "new pond syndrome"; I have a 300 gal horse trough and a 100 gal rubbermaid "skippy filter" utilizing several bushel loads of scrubby pads. Some of these are 3m scotch brite, and some are "Dollar General Store" specials. I've performed a 10-25% partial water change weekly. I have 3 koi, that I feed lightly when the water temp is above 60 degrees F. On my last test, my ammonia level was 0.05 ppm. I have murky-slightly green water......
I'm trying my hardest to keep these puppies healthy until I can setup a bigger pond. Should I remove the scrubby pads and install a different media? I've read a little about bio-balls, mattela, k-1, kaldness sp. (?), etc. I addition to the skippy, should I implement a trickle tower above it, or fabricate a better filter? BTW, I am utilizing a pondmaster 950 gph submersible pump to push water to the skippy.
Thanks for your time, BD1
