    The difference between Solar and Epson salt? or Is there a difference?

    HUGE difference!

    * Solar salt is CHEAP, epsom is not so cheap.
    * NaCl versus some magnesium thingy...

      So will both treat the same problems?

        What are you wanting to treat?

        I'm not aware of anyone using Epsom salts in lieu of plain sodium chloride. I would not do it, simply because ....

          I have heard of some using epsom salts because of medicinal wonders and also because its not so harsh on them you can leave them longer in solution.

          Just based on what I have heard..

            MikeM I was just curious because I have heard of people, dipping their fish in epson salt and as Joe said some say it isn't so harsh.

              It is very different. The regular salt is there to BE HARSH. That's what you want -- strip that slime coat, etc.

              The epsom salt... dunno why it would make a difference one way or another. It is possible that an epsom salt dip could do something but I couldn't tell you what.

                The difference is HUGE...

                Solar salt is regular sodium chloride... made from evaporating out the sea water leaving the salt residue. Solar salts usually have some beneficial minerals that are normally contained in sea water. If you see a bag of "solar salt" it will say something like 99.7% pure salt... the other .3% or so is the natural mineral content of the sea water and not harmful at all to our fish.

                Epsom salt is actually magnesium sulfate and is only called "salt" because it fits within the generic definition of a salt. In chemists terms, a "salt" is a chemical compound that is formed by replacing all or part of the hydrogen ions of an acid with one or more cations of a base."

                While we tend to think of salt as "table salt", in fact sodium chloride, just fits within the generic definition of "salt."

                Magnesium sulfate is used in mammalian medicine to leach toxins from tissue. This is an osmotic ion transfer process that literally pulls the toxins out of the tissue. There is a long-standing and all together wrong old wive's tale that epsom salt will "cure" dropsy. This ain't the case, folks. Dropsy is not a toxin build up in the tissue and the osmotic/ion transfer process that allows epsom salts to work in mammalian tissue does not correlate to fish.

                What epsom salts are good for is raising the GH levels in water. The formula for raising the GH levels with epsom salts is basically the same as using baking soda to raise KH levels... one pound of ES will raise the GH level 100 points in 700 gallons of water. This is not an exact formula but with GH, you only need to be close enough...

                Where many go wrong with epsom salts is using it for the aforementioned dropsy treatment and killing the fish dramatically because of the rapid rise in the GH levels of the water. Goes back to my point about knowing the effects of chems and meds on the water before adding them.

                The last point about epsom salts and GH levels is that the GH, which represents the permanent hardness or mineral content of our water, is achieved through magnesium content. While this is OK for most applications, it is not good for raising fry or building big fish as what these guys need is calcium for good bone development. So, as you consider adjusting the GH levels of your pond, consider your fish's calcium requirements first and then select the right additive for GH adjustment.

                  tweaking GH

                  Calcium chloride, CaCl, (often used as ice melter, but check for additives) is a good way to increase GH. Sulfates can be broken down by certain bacteria into sulfites and hydrogen sulfide, so I would limit the use of Epsom salt (MgSO4) use in ponds. JMO - worth what you paid.....

                    Many moons ago in our koi club we had a lady who used epsom salts to purge her koi going into fall and "hibernation". That's what she claimed anyway. It's the only time I have ever run across it use (rather correctly or not ) in the world of koi!

                      Purge?? Interesting...

                      Dick,

                      How did she use it?? I do know that epsom salts can be effective against some intestinal worms in koi... but of course, the trick is getting it into the intestine. Mixing it with food is do-able but commercial preps such as piperazine are more effective and easier to use.

                      If one listens, one can learn something new in this hobby everyday..

                        Purge is the word. If a fish consumes or absorbes enough magnesium (epsom salts) it will be so regular (moving bowels) that the worms will wish they found a better home.

                          Think of the big picture first Tony then all the details will fall in place.
                          Fish and other vertebrates like us have a common characteristic. The salt content of their blood is identical (0.9% salt solution). This salt or electrolyte is composed of many different substances or compounds. About 77% of the salt is sodium and chloride in our blood. Only 1% of this total salt group or content is Magnesium (Epsom salts). Therefor it is of greater need to re-supply the blood when leakage occurs with NaCl (solar salt) than it is the magnesium (Epsom salt).

                          The next time you get blood work done, note the amount of salts or electrolytes that are measured. Remembering koi have the same salt solution percentages in their blood as we do . For example:
                          Sodium 135-145 (mmol/L)
                          Potassium 3.5-5.0
                          Chloride 98-108
                          Bicarbonate 22-30
                          Magnesium 4.5-6.0 This is an educated guess
