Citric acid/lemon

[Doubleuj]

Pssst, ezi, 9.8 is very alkaline, anything below ph of 7 is acidic. :shhh:

[EziTasting]

No! Say it isn't so! :scared-eek:

Used to think that chlorine was the issue with my bonesai but it's the alkalinity that's caused 95% of my problems ( :D the rest is ALL me!!)

[Dig Brinker]

Chlorine is alkaline!!!

[wynnum1]

Where does the water come from if its been softened that can raise the pH .

[db1979]

Chlorine is alkaline!!!

It's a fair bit more complicated than that.

Chlorine in water takes on 3 different forms, chlorine gas, hypochlorous acid and hypochlorite ion.

When chlorine gas is dissolved/reacted in water it is highly acidic as the product of the reaction is hydrochloric acid and hypochlorous acid.

Bleach is highly alkaline in order to force the chlorine into the hypochlorite ion so chlorine gas is not present (so don't mix bleach with anything acidic in order to avoid making chlorine gas). Bleach is made alkaline by adding sodium hydroxide.

Local councils are responsible for deciding on the final pH of the water that leaves their facilities. If it's 9.8 there will probably be a good reason for it at a council level, or there's contamination of the water supply at Ezi's (such as cracked pipes with leaching of minerals into the water) or the 9.8 was a mistake (incorrect reading or someone at council stuffed up).

I'm not sure, but I'm guessing that pH 9.8 would sting your eyes in the shower.

"carbon dioxide for pH control in water"
Could this make a difference when using for brewing.

I've had our water tested, twice by 2 different pool cleaning businesses and both came in at the same result, well within 0.06 - (2 separate water samples on different days).
At home, with my cheap pH tester it mainly comes up as pH 8ish... so not sure what to make of it...

It is semi hard water - very high calcium content, but not iron ...

How are they treating the water that may be why it has a high ph.

My uncle j has stoped its down to 3 ph what next

[bluc]

Whats the gravity?

[Aussiedownunder01]

will check tomorrow

old post i know but coles and woolies and so on always have citric acid . you will find it in the cooking stuff with the bi-carb , gelatine , baking powder type stuff

Wow I did not know that, cheers texta :handgestures-thumbupleft:

I have found that my local IGA supermarket sell citric acid in such small containers that it is better value for me to buy it from the HBS.

It's worth comparing the HBS price with the supermarkets before you buy texta ;-)

I make my own skun 70 lemons for lemenchello
Put the body's through the mincer then through the juice extractor
Now I am freezing that in ice cube tray's
I pop 2 into a 80 litre tpw
will have enough till next lemon season

On the uj wash stalling ph 3 and gravity was 030
I yeast bombed it no good
Crushed vit b tablets no good
Then put a small handful of shell grit through the grinder and sprinkled over the top its been bubbling happy for almost 2 weeks :razz:

I been reading lately about oyster shells being used for this, it's an interesting concept but being a newbie not sure why & how it works. It just sounds wrong :-B

[bluc]

Oyster shells are high in calcium. Which neutralises acid. When the wash gets to acidic it breaks down the shell in the process balances the ph. :handgestures-thumbupleft:

[Nino]

Oyster shell is made of calcium which is alkaline, the ph of your ferment much have been to acidic for the yeast. By adding the oyster shell it has raised the ph.

Sorry did not see your post Bluc I am a little slow when it comes to putting down my thoughts :)

Im with you Copperhead, I use calcium carbonate myself, the idea of putting oyster shells in my wash seems wrong, even though I know why it works. :handgestures-thumbupleft:
