How can I sterilise newly purchased plants before adding them to my
aquarium?

Against procaryotic alge: peroxide 1:10 for 15 mins.
Against green algae: bleach 1:20 for 4 minutes
Against everything: copper sulphate. I'm unsure of the dose.

although I have beached many plants in the 1:20 solution I would not
recommend it or at least for that long for many plants including crypts and
fine leafed plants. You may want to limit that time for no more than 2
minutes and even then expect losses.


Yeah it's nasty stuff. But I've never lost a plant this way. They may
lose some or all of their leaves but crypts frequently do that anyway
when you move them from a store tank to your own.

Paul Krumholz has shown than 2 minutes is sometims not enough. best to
try 2, 3, 4 minutes, which ever you poick, then quarentine them - his
sole concern is killing green thread algae.

It would be helpful to know what needs to be killed on onincoming plants
and pick the right poison for the job.
