Re: [GSAS-Member] [Where...] one ounce of H2O2

Connie,

Sorry, I apparently missed your last post.  Picked it up here.  Good
question.  I treat a twenty gallon tank with 2 ounces even though it
contains 4-5 inches of substrate plus rocks. I treat a 29 gallon with 3
ounces. From Susan's experience, mixing chemicals should be done cautiously.
Best to do a water change prior to every treatment.  If the water is
discolored from a chemical treatment I would do water changes until the
discolorization is gone before I would apply another chemical.

Connie-
   Here's an interesting bit of fluid trivia:
If you have a water conditioner, additive, or medicine that says "One capful
equals
10ml" then you can use that to figure ounces, because 10ml is approximately
a third of
a fluid ounce. Therefore 3 capsful would be one ounce.

P.S. All physicists and chemists are welcome to tell us if this is wrong.
