Water Curing smell in water storage tank?

[Bud in Fla]

I'm working on a solar system for my garden water that will also be supplying the house in emergencies. I had to do some re-piping to a new pump and decided to pressure wash the inside of the 1400 gallon storage tank. Looks like it's mostly iron/sediment from the well but it smells kinda fishy. On line it sounds like it's a normal, harmless bacteria causing the smell in the now mostly empty tank. I didn't notice before I drained the tank for cleaning.

I don't want to add bleach or pool shock to it since it'll be watering the garden. I've seen that hydrogen peroxide will cure it but it'd take several gallons and would only help for a couple of months. I thought about a zinc anode but I don't have a power supply in that area that would support the electrolysis.

I wouldn't worry much about it except for the occasional drink of water from the garden hose and the possibility that one day that water will be piped to the house - and mama ain't gonna like her house smelling like fishy water!

Any suggestions? Living in west central Fla doesn't help, either. It'll be cool a couple of months a year but that's about it. Thanks for any suggestions!

Add one pint of 35% “food grade” hydrogen peroxide.

And a magnesium anode rod installed in your holding tank will help. Also a zink one wouldn't hurt either

Plumbing supply houses should have them. Just say you need them for your hotwater heater.

If the water is moving threw the storage tank and you can properly ground the tank or the top nut on the anode rod, golden.

Thanks!! Sounds great! Do they need a power supply or will they work like a thermostat or thermocouple on microamps?

I found the 35% hydrogen peroxide at Walmart! It was $28/pint. I found more on line but with the hazmat fee it was $100/gal plus shipping. I'd want to show SWMBO it works before spending it.

In water heaters they work naturally. Sure the movement of the water creates a static charge and the anodes are sacrificing so they will degrade. In water heaters they keep the hard, stinky, corrosive elements in check from attacking the storage tank.

I'll be at the local plumbing supply house in the morning! Thank you!!!!!
