Most of us have some amount of tea color...decay of plants, muck, etc.
I suspect you will have to tolerate it or go to carbon...repeatedly.

Our water is very clear but tea colored. We have got used to it.

Good luck.

Brand new pond!! Approx 8k gallons w/ total of 10.5k gal/hr pumpage (7500
and 3000 pumps - 2 aquascape biofalls). The water is clearing nicely after
only a few days but the water is tea-colored - assume leaching from the
'moss rock' that lines the sides of the pond. Should I do some water
changes to get rid of this OR put some (large) bags of activated carbon in
the Biofalls OR just wait a while?? Have couple dozen mosquito fish in
there now - not expecting to put any 'good' Koi in until next spring. pH is
7.3 or so, and KH is slowly rising on it's own (again assume rock leaching),
initially about 75, now about 125. Totally jazzed to finally get this done -
been about 10 years in the dreaming / planning stages. TIA for any comments.
