Penny Wort is the common name of a couple of different species.
Hydrocotyle is the most common botanical name when you are talking about penny wort for aquariums or ponds. There are several species of Hydrocotyle.
Lysmachia nummularia is another plant that may be called Penny Wort. It is also called Creeping Jenny. It is not a true underwater plants, but thrives on the margins of a stream or pond.
Wort is a common name that means soft plant, herb, non-woody plant. Penny Wort could be used for almost any soft plant with round or nearly round leaves.
To make a plant dip, it depends on what you are killing.
Select the chemical that will kill what you want at a dose that will not harm the plants.
Also, figure out what will break down that chemical, and have it ready.
Here are a few examples:
Bleach: If you have the old laundry bleach (not the concentrate) then 19 parts water: 1 part bleach is generally safe for most plants, but the duration is important. The softer the leaf, the shorter time they should be exposed to the bleach. From about 10 seconds to 2 minutes is common.
To deactivate bleach have a bucket with a double dose of dechlor ready to dip the plants into when the bleach treatment is complete.
To deactivate it- don't worry about it. The trace that lingers on the plant will not be a problem in the aquarium.
To deactivate it have a bucket with hydrogen peroxide in it standing by.
Excel: Do a dip with the highest recommended dose.
To deactivate it: Don't worry about it, the trace that lingers is not a problem for the aquarium.
there are many other things that will kill algae, snails and other invaders.
