Potassium Permanganate?

Surely you know the wonderful properties of silver don't you?   Just throw about 100 silver dollars in there, that should take care of things.

Potassium Permanganate is an oxidizer used to bind with & drop out mangenese & iron from water during pretreatment. It is highly corrosive to all metals it contacts. I believe it would be a poor choice for contained water.

Most likely a light does of Good Ol "20 Mule Team" aka Borax, 2-3 times a year.

It is the fungicide all us old boat owners use.

Sorry all, I had NO idea it was so corrosive! I knew that it would cure athletes foot, and keep chickens healthy, and is cheap, thus my thoughts about it being a fungicide. I will keep my silly-assed opinions to myself now. :-[

Potassium Permanganate?   

Buy enough (if you can find it) and the ATF may come knocking - used in explosives too.    All the stuff I used to buy at the drugstore when I was a kid, and now you have to have reams of paperwork to get someone to even admit they stock it...

Ron,
No problem here. I just built a two tank storage system with two pumps for Sodium Permanganate (which replaced the old dry mix Potassium Permanganate system). Have rebuilt the pumps a few times over the years, and maintained most of the associated plumbing, YUCCH!

Most of the 3-4 letter government agencies are interested in anyone with this stuff that shouldn't have it.

Marcus.
I don't think you'll have to worry about you tank, as long as you can get the temperature up to about 60C once in a while. There are lots of tanks here and i've never heard of one failing due to corrosion. The water looses its oxygen after a while and becomes "dead" as we call it. Without oxygen there can be no corrosion.

I hope my explations makes sense ???

The only metal in the tank is copper coil and a few bronze fittings.

Electrolysis.  Sacrificial Zincs

Just as an FWI, sacrificial zincs are not sacrificial at higher temperatures. If you have steel tanks you need the anodes sold for water heaters and they are not zinc.

Water heaters typically come with either magnesium or aluminum anodes.  If you are on a well and you have rotten egg smelling hot water (because of iron/sulfur anaerobic bacteria in your well water that happily lives and creates lots of hydrogen sulfide gas inside your sunless, low O2, 130 deg F water heater tank environment), one solution is to replace the magnesium or aluminum anode with an aluminum/zinc anode.

I agree Marcus doesn't need anodes but I did some research on anodes for my tanks.
Magnesium is the least noble metal on the galvanic chart and is best used in fresh water.
We both want to prevent algae and fungus growth. Bleach, algaecide, fungicide, biocide, darkness, heat, anaerobic environment, I don't know. I'll take a few precautions and see what happens. For all I know a little slime on the walls wont hurt anything. We're not drinking the water, just using it to store heat.

Thanks, Geno

Except that it insulates the heatex pipes, and slows down heat transfer.

If it were me, I think I would just setup a system to periodically inject bleach so as to maintain a low free chlorine level (Google "free chlorine test kit" if that's not a known concept).  Set the injection schedule to maintain a minimal free chlorine level to keep stuff from growing, but not so high a level to damage anything in the tank.  Here's one way to inject bleach into a pressurized water line:

For a tank vented to the atmosphere, a pellet feeder (maybe a DIY version) might be the way to do it.
