I have a 1400 gallon pond and
have a 40W UV filter, Pool
size sand filter and have a
Veggie/bog filter. I have 9
koi that vary in size. 5 are
about 11inches, 1 about
10inches, 3 4inches and under.
3 of the fish I need to catch
and give away...they are ugly
babies that grew up. They are
so hard to catch!

I am tired of replacing the
sand every spring due to the
channeling I get. I am now
backwashing two to three times
a day.

But once I change out the
sand...which is actually a
fine pea gravel (coarse grade
red sand), everything is fine
for one season. But I would
rather not change that every
year.

My pond is always crystal
clear, no problems that I can
see, I dump some Microbe lift
spring/summer along with some
koi clay and the string algae
dies off that grew over the
winter and that is what starts
the problems with the sand
filter. I think if I could get
the string algae to NOT grow
at all I would not have this
problem, but that is never
going to happen.

Can I put bio balls in my pool
filter (Triton II)? I like the
polished, clear water I have.
Would I have the clear water
with the bio balls, but give
up the crystal clarity as I
get with the sand?
