build a veggie filter. Jo Ann told me this morning that her ammonia
is almost gone entirely. The water celery (not lettuce) I sent her 12
days ago almost entirely fills her 3' pond she is using as the veggie
filter. she now is seeing mulm accumulating in the bottom. her water
is crystal clear. Jo Ann has a 10,000 gallon pond with 40 huge koi in
it. Ingrid

I have a 1200 gallon with a small number of Koi and am now using a
TetraPond. Its a gravity system with plastic media and a small sponge on the
top. The water gets cloudy since the filter doesnt filter small particles
from the pond. I do 50% water changes or use polyester floss which works but
is too my maintenance....
Looking to upgrade to a better filter....
Any suggestions are welcome....

Thank you
