Who didn't know that bleach expires?
Okay, it looks like many of you know this already. But for those that didn't...
I was all set to nuke my black bush algae contaminated plants with a bleach/water solution this evening when I noticed *sniff*sniff* my bleach didn't smell like bleach.
Thinking it ought to smell...er...bleachy, I asked the internets. Turns out bleach loses its effectiveness over time.
WHAT??? So you're telling me this dusty....*checks date* bottle of 10 year old bleach isn't any good????
Apparently so. And usually it's only good for about a year or so.
So for those of you needing to disinfect aquarium equipment (or plants in my case) and like to use a bit of bleach - check the expiry date on it. If it's past-due, you might want to think of getting a new bottle.
I know I am
