Question #1>

Hello Carolyn,

I have a SERIOUS silt problem. HELP


Answer #1>


Silt can be dislodged by a stronger stream of water, basically by
adding more water flow in the pond. However, if it is building up
on the bottom, and you can call it sludge, then you may need to
either vacuum it or you can try using Microbe-Lift Sludge Away,
the bacterial additive that solubilizes hard to break down
particulate matter on the bottom of ponds.

Either way it will be beneficial to increase the aeration to the

And the third way is to completely empty the pond, wash it all out
and refill using dechlorinator.

Question #2>

Hi Carolyn,

I think " today's pond question" is really great. I get some useful
info from it.

I've recently noticed that the gills on a number of my koi heve
begun to flare at the opening. the go normal and the kind of kicks
up at the end. Other than this they all appear ok. But more seem to
be developing this appearance.

The kois are between 2 & 3 years old, 12 - 14 inches and their gills
only started flaring a few months ago.

Any ideas on what the problem may be?


Answer #2>


That may have been when you first noticed or you may be feeding high
growth foods that aren't meeting their nutritional needs?

Koi need good sources of stabilized Vitamin C, all protein,
carbohydrates and fats in the correct proportion in their diet, and
this is the very reason I tell people not to keep foods from year
to year.

Always use fresh food, especially during the growth stages, or you
will find nutrition-based defects. I don't know which it is in
your case, but these are just a few things to look at.
