I asked Michael at
www.canberaaquatics.com.au if the product "No Planaria" was safe with axolotls (he wasn't sure by the way, never seen it tried, so that question is unanswered)
I also asked him if the "NO Planaria" could be used to clean plants in quarantine.
Below is his reply FYI -
Hi Bren
No planaria will not treat all the nasties that can find their way into a tank via plants. For treating or quarantining plants before they go into a tank I would first use the below methods,
There is a few methods for treating plants before placing them into a tank. A 1:19 bleach dip for a couple of minutes then thoroughly rinsing the plants. Many sensitive plants such as vals, liverworts, mosses certain stem plants may be damaged by this. Plants with a good rhizome such as crypts or ferns are generally more resilient to this type of treatment, you may lose some leaves but the plants recover in most cases.It is important to use a bleach that is just that, bleach, and contains no scents or any other additives. Home brand bleaches are generally a safe bet.
Potassium Permanganate (available from most chemists) is another common chemical used to dip plants in, a dark purple solution is made in a bucket and plants are soaked in this for 20 minutes and then thoroughly rinsed. Even just a good rinse can also help to dislodge some bugs too. PP is less harmful to plants, but may not be as effective against bugs. (I would advise doing this outside and wearing gloves, this stuff will stain your hands a nasty bronze colour!)
An Alum dip is the other commonly used method for treating plants, a solution of 1 tablespoon per 4L of water can be used to soak plants in, a soaking time of a couple hours is generally used. And as with the other two, rinse thoroughly before placing in your tank.
Many people will then place the plants straight into their tank, if you are a bit paranoid or want to be certain you could then place the plants into a quarantine tank to watch for any signs of bugs or if anything hatches (snail eggs can be a bit resilient)
Hope this answers your questions.

It seemed like a balanced and reasonable point of veiw, and some good methods there
