How do I treat an aging barrel?

[Patr1ck]

Im having a disease outbreak in my tanks. How do I treat the water aging barrel to ensure that no bad guys are living in there waiting to reinfect the tank once the fish are back to normal? Do I use bleach and circulate it around the aging barrel? If so what concentration?

Thanks,
Pat

I am not a huge fan of bleach and discus mentioned in the same sentance but I know people who use it quite strong and then wash out with white vinagar after.

I have used PP to sterilize nets and tanks. Not alot will survive 5 - 10ppm of PP.

I have used pp and I have also used bleach. (not at the same time:))
You can use bleach if you rinse it out several times really well. I just pour in some bleach 1 or 2 cups. for a 30 gal barrel, add a few gallons of water and use a scrub brush on it. Rinse, rinse, rinse
I then dry it with paper towel and then put water in with lots of dechlor to be safe. rinse again and use.

If you use pp, be sure to neutralize it with hydrogen peroxide before flushing it down the sewer.
