— Is it Safe to Use Levasimole HCl Powder in My Aquarium?

Subquaria research shows that Levasimole HCl Power is safe for use with: Fish, Plants, Bio-Filters & Shrimps.
As an added benefit, it also boosts the immune competence of fishes.

The LD-50 (the lethal dose of a compound for 50% of animals exposed) of levamisole is 250 mg/l per 24 hours.  This level of dosage doesn't even come close to what was suggested for use in a water bath (the method used in our fish tanks). Only extreme overdosing with this medication will result in death to your fish. Few accounts of adverse side effects in aquaria have been noted even with much higher than currently accepted appropriate dosing.


Easy Instructions for Aquarium Use:

1. Feed your fish as you normally would.
2. Remove active carbon and UV lights from your filter (if any).
3. Do a 50% water change with your favorite de-chlorinator.
4. Add Levamisole HCl Powder to your aquarium and keep the lights off for 24 hours.
5. After 24 hours, do a 75% water change with your favorite de-chlorinator.
6. Repeat this process in 3 weeks time.


              Not safe for Neon/Cardinal Tetras, Scaleless Fishes nor Snails

 •• You may need to apply the treatment several times to fully eradicate parasites •
There is some question about the Levamisole killing eggs in ripe females.
These eggs could be expelled after death and remain viable to hatch into more worms.

• I had never heard of type of fish that are extremely sensitive to Levamisole HCl, however, you are responsible for doing your own research before medicating.
• Please be aware that Levamisole HCl does not claim to kill every type of worm or parasite, nor is it a miracle drug.
• The results you see depend on a variety of factors. We do not guarantee results.
• You understand in an event where a fish dies after medicating, normally isn't directly related levamisole, but instead the severity of damage caused by parasitic infection depends on a number of factors. Number of worms present in the fish, age and species of the fish and the sites of infection all affect the level of damage  caused by the parasite. This could be prevented if treated early, but if left untreated for long period, it would just be a matter of time before before the fish passes regardless of medicating or not.
