Pond Salt
Hi Guys
I have a dilemma I want to use some salt in my pond BUT....... All my local suppliers ie: Aquatics Centres have a product PDV (pure Dried Vacuum) Salt This has Anti Caking agent E535 (Sodium ferrocyanide) They are ALL totally adamant and swear they have used this product for 20+ years with no problems Several of these suppliers have Very large stocks of BIG Koi in ponds with this salt added.. BUT According to several web sites I have looked at ie: www.puregold etc They say NO to this additive as it turns to Cyanide when used........ What should I do? Chris |

I've nerver heard of using this product for live garden ponds. If anyone else has any experience with it, please speak up. I use about a half a cup of sea salt, and about a half a cup of epsom salt. I add it after every other addition of water (about once a month), after which I check the water quality. |

Morton's has it, so "when it rains, it still pours". It is potentially toxic to fish. Table salt may contain up to 13 ppm YPS, and does not have to be listed on the label, per FDA regulation (21 CFR 172.490). When exposed to sunlight, ultraviolet light rapidly photolyzes YPS to free cyanide. US EPA lists cyanide as toxic to fish at 0.022 ppm (acute toxicity) to 0.005 ppm (chronic toxicity, "96 hr LC50" means it kills half the fish in 3 days). Fortunately, cyanide isn't persistent; it evaporates readily and bacteria can destroy it. At the oft-recommended 0.1% salinity, salt with 13 ppm YPS would put 0.013 ppm YPS in the pond, which could photolyze to 0.0044 ppm HCN, which is near the toxic level. If higher salinities were needed for disease treatment, cyanide could exceed toxic levels. If, on the other hand, lower salinities were used (e.g. 100 ppm for prevention of nitrite toxicity), the low cyanide level would not be of concern. I use solar salt crystals, coarse 1/4 to 1/2 inch in size. It doesn't seem to contain YPS (humidity causes it to fuse into a lump, which I break up with a hammer or boot). An 80 pound bag was $6 on sale at Lowe's. - Rod Personally, I get Morton's water softener salt in the blue bag without conditioners, 99.9% pure I think it says on it, no anti-caking chemicals and only ~$4/40 lbs. ~ jan (Do you know where your water quality is?) |

forget that stuff. get plain old 100% rock salt CRYSTALS not sea salt... in plastic
bags meant for water softening. it is cheap and great. Ingrid "ciel" wrote: Hi Guys I have a dilemma I want to use some salt in my pond BUT.......

Bonnie,
Let me throw this into the works. Solar salt only means that it has used the sun energy to concentrate the salt. I used to live in front of salt evap ponds that were being used to concentrate the sea salts in to brine water requiring less expenditure of energy for making the final product. Just because it is solar salt, that has nothing to do with anti caking materials and I should point out that since the salt you are talking about is not meant for human consumption prese, the makers/packagers of the salt are not required by law to list additives at all. Have you ever thought how or why that these salts do not seem to cake together when you are pouring it out of its paper bag? Just thought you would like to know.

Chris,
In pickling salts you will find no anti-caking materials, because they interfere with the pickling process. In some stores it comes in a grayish bag. In any event, just look for pickling salt. Some stores have all the canning items in one area and you will sometimes find the pickling salt there in that area.

Jan,
Rod really doesn't know what he is talking about when he refers to Morton, because Morton has not used YPS since the late 1940's. I asked Morton, so I know.
