What was that ratio again Drylander?...one gallon of Jack Daniel's per bottle of water. I think you need to re-calculate...unless the bottles of water are very small ones. Come to think of it, a tank full of rum wouldn't go bad as quickly as a tank full of water...just not likely to last as long.

The amount of added water is in reverse proportion to your income. I am sure my CEO does not add water at all. I am just not there yet... financialy...

I agree with sailingdog on everything but it is not really a good idea to have a chlorine concentration more than 1/4 cup per 15 gallons. The concentration does just fine and can be repeated. Above that level is just asking for trouble on gaskets, hoses and attaching points. It also gets to the point where it could be harmful to your future water supply as it is corrosive and makes the surfaces rough.
If two aspirin work, 5 will work better. Don't do it!!!!!!

The point is to clean, purify, and kill bad bacteria. Chlorine kills plants, algae and bugs that grow in water. One celled living stuff.
Vinegar kills bacteria.

Black algae sinks it's roots into surfaces, and should not be there if you are using city water in the first place. It is resistant to chlorine and can only be attacked by injuring it's protective skin. Only done by physically scrubbing.

That is an educated pointer but you certainly don't have to listen to me.

If it doesn't move SHRED IT!

oh oh Skyellab - stand by for the fallout by disagreeing.

Glad you reiterated the point about cleaning in addition to disinfection.

Too much Cl solution can arguably be dangerous and create unintended contaminants where none previously existed and as few have the ability to test for residual Cl conc, it is usually wiser to use too little than too much.

Paranthetically, although not as widely available, peroxide solutions in high enough conc can be equally effective, have a longer residual effect, do not have a deletorious effect on aluminum and leave no residfual taste or odor and thus is a more preferable method of disinfection.

I am not disagreeing, I am trying to save people some expensive repair bills.

The hydrogen peroxide will not take care of the problem first asked about.
Then on another note you will have hydrogen gas in your lines and tank.

Boom!!!!!

Just stick with the tried and true 1/4 cup chlorine to 15 gallons water for at least 12 hours followed by 1 quart of vinegar for every 5 gallons water.

It will be fine!

You are certainly correct that peroxide will certainly not cure a fungus problem but is an effective disinfectant. I can't imagine a scenario in which any type reaction could occur which would generate an explosive mixture above any reasonable LEL. It is theoretically possible to generate oxygen (which isn't explosive) but inconceivable to generate hydrogen.
Can you think of a possible reaction that could generate H gas?

Cool

Ok hydrogen peroxide is H2O2
Water is H2O
Oxygen cleans things. Oxiclean
In a closed system you could have a chemical reaction which is anyones guess.

The H2O2 would form H20 which is water and the free O combines with something.

It has been proven that Hydrogen Peroxide does not kill much and alcohol also is limited as it drys things out to disinfect. Hepititus which could be present in water if it wasn't processed properly is bad. Bleach kills it, and H2O2 does not. Alcohol puts it in a dormant stage that if you add water makes it active for up to 8 weeks. Do you want to clean the water and make it safe or ?

Bleach and vinegar!

I'm done with this post. Just thought I was helping.

The 1/4 cup per ten gallons is what was recommended by Peggie Hall's technique and seems to be fine, with little damage done to hoses, seals or other such equipment. 1/4 cup per 15 gallons is a much weaker solution and I would rather use the stronger solution once, than have to repeat the weaker solution. I only advocated repeated use of the chlorine shock treatment in this case, because the tanks have been neglected badly by the sounds of it.

The point about black algae is very true... it forms a protective layer that may be killed off by the bleach, but the underlying portions would not be affected to any significant degree.

Vinegar does kill off mold and bacteria, and can often be used to prevent mold growth from occurring on hard surfaces... but IMHO its main purpose in shock treating a tank is to help neutralize odors... which is is also very, very effective at.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
