KH & GH
Pardon me for asking a dumb question but.... (Still new to some of these
things)
What is KH and what is GH? pH I know.
Thanks.

Ok, rough math: ~ 3/4 cup of baking soda will raise the KH by 1 drop
(about
18 ppm) in 2400 gallons. You didn't mention what your current pH is, but
baking soda will not raise it above 8.4 (max). My pH still "fluctuates" a
bit: 8.2 AM/8.4 PM, 8.3 average - rock solid. If you want to take it
slowly,
add 3/4 to 1 c of baking soda daily until you get your KH up to 9 or 10
drops (minimum). If you have a bead filter, get it up to 12 drops.

Thanks, Lee. How much will 1 lb. of backing soda raise the pH? I don't
want the pH to skyrocket with the fish in the pond. Not a good thing.
Don't forget I have 2400 gallons of water. Thanks.

Raise your KH with plain ol' Baking Soda. Arm and Hammer kind, but
doesn't
have to be the name brand. Get your KH above 150 and maintain it
there.
At
that range, you will be protected against pH crashes. Right now,
you're
DANGEROUSLY close to one with a KH around 40 or so. If you have a bead
filter, get the KH 200. Use 1 lb. per day until you get it up. If
you
have
rain, you will probably take steps backwards. Baking Soda is the
cheapest,
fastest way to get your KH up and keep it up. After you get it where
you
want it, you can probably maintain it with weekly doses. KH can be
500
or
so without doing any harm, so don't worry about overdosing. It will
also
stabilize your pH around 8.2, keeping it rock solid. I don't worry
about
my
GH too much, just the KH.

I need to raise the KH & GH in our pond. Our public water is on the
soft
side and we have been having constant rain. The GH is usually at
120ppm
and
KH at 80ppm. This morning the GH was reading 50ppm and KH of
40ppm.
This
afternoon the KH is around 80ppm and the GH is still at 50ppm. The
plants
are letting me know that they aren't happy but the fish seem OK, so,
far.
I
know I need lime for the KH and gypsum for the GH. And, I know
there
is
a
difference between dolomitic and dolomite limestone, but which one
is
the
right one for the pond? I will be going to Home Depot, so, what do
I
need
to get and how much. Our pond is around 2400 gallons. Thanks.
