swimming pool - how often to add alum?

[John Smith]

The guy who maintains my swimming pool adds alum weekly. It is really
necessary to add alum so often? Most of the time, the water is crystal
clear. It becomes cloudy after alum is added. Why adding alum to clear
water?

I assume alum works as a floculant to bind tiny particles together which
clears cloudy water. Never had to use one on the pool here. But from
what I know about pools, they are typically added only if you have an
actual problem. Any history of the pool being cloudy frequently in
the past? But then there are all kind of theories out there
about how to best manage a pool. Who pays for the alum? If it's not
included in the service charge, paid for separately, I'd tell him to
stop unless there is an actual problem.

But it's in your baking soda.

Soda alum has the formula NaAl(SO4)2·12H2O. It is used in baking powder and as
an acidulent in food.

Alum is Aluminum Sulfate.

Big difference between metallic Aluminum and the various Aluminum
compounds. Not that I shun aluminum metal either.

One of the effects of Alum is to remove heavy metals from the pool
water. Certainly a good thing.

Alum is also used to treat drinking water. Use too much and
you get Hydrogen Sulfide (rotten egg gas).
The Hydrogen Sulfide is toxic, but:

Since hydrogen sulfide occurs naturally in the body, the environment
and the gut, enzymes exist in the body capable of detoxifying it by
oxidation to (harmless) sulfate. Hence, low levels of hydrogen
sulfide may be tolerated indefinitely.

I haven't used Alum to treat my pool, but reading how it works,
I don't see a problem.

But then, I'm not one of the new breed of humans running around
that seem to fear everything.

A United Nations program affiliated with the climate change group did research showing that water is toxic. A group of convict volunteers were used in the tests. 10 gallons of water was pumped into each convict and they all died. So it's official, water is a toxic substance. ^_^

If you have cloudy water, then you can use it to clean up the water on an as
needed basis. I don't think doing it weekly is necessary. After your
maintenance guy adds it to the water, does he come back in a couple of hours and
vacuum to "Waste"? More info here:

Baking powder is available both with or without aluminum.

Not all "humans". Just a lot of Americans, Canadians and Europeans.
The rest of the world lives normally.
