High Ph

I will probably be posting regularly for a while untill not only my
pond is in balance but my understanding of it all I have been
bringing this pond back to life for the first time, for me. I am in
sunny Austin, Texas. I felt like I was making excellent progress with
the 'health' of my pond till the last 3 or 4 days. Since then I have
noticed String Algae developing (water is clear) and my ph rising
steadily. Ammonia, Nitrates are at 0, Nitrates minimal if any. Don't
have a hardness test. While I haven't been testing it very long I
felt like my ph WAS normally around 8/8.2, apparently about the norm
around here. Now I am getting readings at bottom of my chart which
only goes to 8.8 and I suspect my color is higher than that. I may
have done (at least) 2 things wrong. Most of my numerous plants and
lillies have only been there a few weeks. When I potted them I did
use a topsoil mix which had no vermiculite, fertilizer etc. but was
somewhat loamy, sandwiched top and bottom by pea gravel. Perhaps no
coincidence 2 days after building a little in-pond stack of river
rocks and Moss Boulder to create a simulated waterfall splash (from my
outflow pipe) I noticed my ph rising (also so did the temperatures and
sunlight). I have been using the same material to raise my pots. So
I guess this post I am soliciting advice as to a direction to attack
first. Most likely the rocks, soil or other things. My first 'bloom'
I really panicked and I don't want to repot all my plants, put them on
what and take away my waterfall, if this is just a balancing thing
that requires smaller adjustments. Thanxx - Bill

What time of day are you measuring pH?

Diana Walstad reports of a sof****er lake that changed from 5.7 in the
morning to 9.6 at noon. I
this is due to the plants drawing out the CO2 from the water.

It appears to be bass ackwards. As far as I can tell from my narrow

Would water hardness (which I can't currently measure) make any sense
of this. I would guess our water is a little hard, but not sure.

Both readings appear to be fine to me
You can get the KH measuring 'kit' at PetSmart, etc. Very
reasonable.- around $5 to $7.
It is one you really shouldn't be without.

There are two hardness measurements GH or general hardness is usually
a reading of calcium and magnesium. KH or carbonate hardness
measures the buffering agent in the water that keeps the pH from wild
swings.

Plants use sunlight and carbon dioxide to make food and release oxygen
during the day, but oxygen is used at night when the sun isn't shining
and carbon dioxide is released into the pond making carbonic acid,
which lowers the pH reading at night or early in the morning.

Before you use a pH down agent check the KH, or try baking soda first
if the pH is too high. Baking soda, sodium bicarbonate, is a great
pH buffer.

yes, if he doesnt have much alkalinity (calcium) he needs to add some organic
dolomitic limestone to buffer the water. I have lake water with some calcium, but
not enough so I add dolomitic limestone to make sure I got good buffering.
good loam and pea gravel will not affect pH. ammonia can drive the pH up tho.
