I read the article. It appears that the H2O2 method with an IV dripper may
work and be cheaper/easier to **try** out at least. What level would we
start at now then? 1 drop every 10 seconds of 3% solution for a 100 gallon
tank? Since it kills mainly new algae growth would not a UV sterilizer do
the same thing essentially?
This method is great for a pond and large applications but what about our
tanks? Adding H2O2 to a pond all the time is nutty/impractical, but the
cheap straw method is not. Adding straw to our tanks can present issues, but
the H2O2 much less so. Comments?
