and im going to play the devils advocate against myself here....the amount of bleach that users r stating that add is sooo minimal that it is practically a minute(mi-noot) amount of sodium that it really doesnt matter huh??
but krunch dont you prefer h202 over bleach???
i used both, but found i was using alot of h202, it was hard to keep the rot in control....
with the bleach it was 2 ml's per 10 gallons and the rot was gone.....
