FYI:
Salt, or sodium chloride (NaC1) in its chemical form, is a commonly use
substance in aquarium culture.
Many forms of salt are used, including table, pickling, and cooking salt. Of
these, the most commonly used and least expensive form is cooking variety.
When used properly, salt can treat many external parasites including Costia,
Epistylis, Trichodina, Chilodonella, and the flukes Dactylogyrus and
Gyrodactylus. (Gee! I would like to see Roy's spelling of those words) Salt
can also be used to relieve stress during handling and transport or when
reading the RML!!!.
The method of salt application depends on the disease organism and fish
species. Treatment methods include short-term dips, prolonged baths, and
indefinite treatments.
· Dip treatments involve exposing the fish to very strong solutions for
short periods of time, usually 30 seconds to one minute.
· Prolonged baths are useful for treating fish in small tanks that can be
flushed quickly. Strong solutions of salt are added to the water. Fish are
held in this salt solution with aeration from 30 to 60 minutes, or until
they show signs of stress.
· Indefinite treatments are used when transporting, or when dealing with
large volumes of water, such as ponds. Low concentrations of salt can be
used indefinitely in ponds.
Specific treatments and methods of using salt for treating various diseases
or as remedial treatment of stress
External parasites Costia, Epistylis, Trichodina, and Childonella and the
flukes Dactylogyrus and Gyrodactylus 10.000 - 30.000 ppm (1 - 3%) prolonged
treatment (30 minutes or until fish show signs of stress) or 1000 - 2000 ppm
as an indefinite treatment
Stress during transport and while handling - Indefinite treatment using 1000
- 10000 ppm (0.1 - 1.0%)
Perhaps I should share a quote from Ruskin with you all!
"The more I think of it, I find this conclusion impressed upon me, that the
greatest thing a human soul ever does in this world is to see something and
tell what he saw in a plain way"
