Re: alage control/H2O2 and straw

Tom Barr asked concerning H2O2 (hydrogen peroxide):

That's an easy one Tom. All of the fish would be floating belly up, dead
snails would litter the substrate, and all of the plants would be brown.

IME, a level of 1 oz per 12 gallons of water (if added at one time) is
safe, even for Krib fry. However, if the tank contains Otto's, you
should reduce that to 1 oz per 20 gallons. If it's a plant only tank,
you can increase the amount to 2 oz per 10 gallons, but this level will
kill snails, knock the plants back a bit, and set the tank back to
square one in stabilizing. Hope this gives you some idea as to a
starting point for your IV drip. 

Question. How long does H2O2 stay active in water? I read somewhere a
while back (can't remember where), that H2O2 drops the extra hydrogen
atom and reverts to water after 10 hours.
