I use 99% sodium dichloro-s- triazinetrione- which is commonly sold.


My bottle of clorox in the laundry room is:

6% sodium hypochlorite

94% "other ingredients"- which are not specified.


the liquid chlorine we get from the pool store ( when needed) is about 18 to 24% chlorine.

afaik the pool shock is the closest you will get to 100%

and this is max 4 table spoons added to 20 to 30 gallons of water when cleaning tank.
general use is 1/2 that, and the crystals are easy to handle

It took a couple of days and some elbow grease, but the tank and lines are all nice and clean again. Thanks all, for the advice.

Let the bleach and water mix sit in the tank for at least four hours - no less. More is OK but the bleach starts to dissipate to water after four hours.

And there are chemicals in Pool Shock OTHER THAN just chlorine that you should not have in a drinking water tank . Clorox is less that $2 a gallon and you wont be using a whole gallon to clean it

I use about 4 tablespoons of "di-chlor" pool shock in mine to a full tank.

mix it up and drive around- let it sit overnight and drain...you can also run through your tubing to help clean it out

I pour the pool shock into a thick walled cleaned and dried plastic water bottle- Perrier at the moment- and the shock is protected from spilling or moisture- the neck makes for an easy pour. easier than carrying around bleach and a higher concentration ( some household beaches are about 7%)




this can also be used to treat "suspect water" while camping- but just 1 or 2 tablespoons per tank.

a bag of shock will cost a couple of bucks and last a few seasons.

we have a pool so I have the chemicals anyway

the tank is clear?

There's plenty of light, reflected off the concrete it's parked on.

If there is no light, I dont think there is algae in the tank. But a bleach shock out to do the job.

Treat it again with bleach (one cup/50 gallons). Let it sit for several hours, repeat if necessary.

This concentration of bleach is for shocking the tank, not drinking. Use one teaspoon per 5 gal for drinking water treatment.

The plastic hasnt been hurt at all but do MANY "water and Clorox" flushes. Fill no more than halfway and drive around some...SLOSHING the mix in the tank. Drain...do a fresh water rinse and drain and then do the Clorox deal 1 more time if you think you really need it...along with a straight water rinse...and your good to go
