Alkalinity

Yes, just a color comparison. After looking more closely, there are numbers
to go by. I would say I'm around 40-ppm Alkalinity. Should be at 120ppms

No number, just a color? ~ jan

How do I raise the alkalinity content in my pond water, its low.

What is the measurement you are getting and how are you measuring it?



What was the measurement that you got?

I'd want to raise that too. ) ~ jan

That is a little low, but not dangerlously so. If it were me, I'd just add
some limestone rocks to the pond and leave it at that. I have a limestone
waterfall, and my general hardness stays right at 80 mg/L, which is normal
for freshwater ponds.

And they're totally safe. They raise it slowly and gradually - no shock to
the fish.

Exactly. And the limestone keeps the alkalinity from falling.

Like how much Limestone. One big piece or smaller ones. Thanks...

In fact, the more that the alkalinity falls (i.e., the water is
becoming acidic), the more likely the limestone will react with
the acids in the water to, um, increase alkalinity.

This is why certain fine organic sands are to be preferred in a
marine environment, where higher alkalinity is particularly
important.

In a marine environment, it is critical to have either aragonite sea sand
or a crushed coral substrate to prevent both Alkalinity and pH crashes.

I don't know that there is a specific formula as not all limestone is the
same. Limestones vary greatly in their solubility and hardness. I have
about 300-400 lbs of it built up as a waterfall and for structural support
for my biofilter in one end my 1,400-gallon pond (although not all of it is
under water). Nearly all of it is dolomitic limestone (high magnesium
Limestone containing a significant fraction of dolomite), so it is harder
than pure limestone (which has calcite as a primary mineral) and has a
relatively low solubility. Even so, enough of it gets dissolved over time
that it keeps both the pH and the alkalinity in the proper ranges. Oh, and
always clean the rock before use.

Oh yea, and you should have these rocks in an area where water can flow
over them. It helps.
