Default Lowering pH

Bob, isn't the KH low though? I know baking soda will
raise the KH -and pH will stablize at 8.4 - but I have no
idea what baking soda will do to lower the pH. Seems
like the buffering should also be addressed.

Baking Soda will also lower the Ph to 8.4. Its strange but it will
raise it if its low, and lower it if its high.

I have tried to stabilize my KH/GH/PH for a 10 day straight period I
by added baking soda and limestone every day in the amounts that Rod
recommended.
(6oz baking soda + 1 1/2 oz epsom salt + 6 oz pelletized limestone
daily to raise KH/GH each one degree daily. He recommened this slow
raise due to fish in pond).

Note: I was only able to find the one type of limestone here.

It hasn't worked. I think because of all the rain we get here in
Florida (we have had rain every afternoon for at least a month now).
I finally gave up. Any ideas on how to overcome the KH/PH flux with
all this rain?

Last reading were KH 180, GH 150, but PH bounces from 7.8 AM to 9+
late afternoon. I was not able to get either the KH or GH any higher.

Pond is in full sun so heat is also a factor as water gets to high
80's. I'm running a 22' stream into 1650 gallon pond stocked with 70
bunches of anachris, a few reed plants, a half dozen iris and dozen
water lilies which right now are covering about 1/2 the surface. Pump
is a 3600 pondmaster going thru a Savio skimmer with one filter pad in
it. Savio has only been running for the last month. Pond is stocked
with 9 Goldfish (3 are babies about 3" long, other 6 range from 6" up
to 9"). I only feed the fish occasionally (maybe once a week). Pond
has been up and running since early May and I can only see down about
10" due to brown algae. Getting ready to install my biofilter in the
next few days. Any suggestions?
