bigspizz;1153068; said:Well put, but, without backing for such a claim. I have researched and posted the opposite opinion with credited links, to back the claims I made. Carbon and salt, until NASA researches it in space will be debatable topics. There is no (for now) definitive answer, and it is up to us, to read between the lines on this one, till a proper study is done by NASA, Harvard, U.W <<(lol) or some other establishment who has the funds to do it right.....

I use 1 tbsp/5g for general fishkeeping, more as medication. I find that the fish tend to keep a better slime coat and brighter colors with the small ammount of salt than without.
Pufferpunk;1153292; said:Great response! So, I guess it would be similar to us drinking salted water all the time?
MarlboroMan;1154629; said:Salt is found in rivers, lakes, and ponds. Salt is scarce in tap water. Your freshwater fish would prefer a little salt. If you don't think so, you know jack about biology.
No, that was not a typo.DasArab;1154993; said:btw Pufferpunk everyone knows that yo never ever add table salt to an aquarium so im assuming that was a typo![]()
Sodium chloride is the familiar white crystalline material in just about every kitchen. Table salt as purchased at the local supermarket in this country also contains iodine and anti-caking compounds.
Iodine is a halogen, and is required for vertebrates. It is necessary for our metabolism as an essential part of thyroid hormone, which is our metabolic pacemaker. Soils in wide areas of this country are deficient in iodine, and can result in goiter (hypertrophy of the thyroid gland, effectively from insufficient iodine intake). Thus the practice arose of adding iodine to salt intended for human consumption. This was the safest (the levels of iodine are minute) and surest way of protecting the population from this deficiency as salt is ubiquitous (all but universal) in food processing and preparation. The levels of iodine added to table salt are so small that any water-living vertebrate would be pickled in brine well before toxic concentrations of iodine could be reached, so that particular urban myth is without foundation. In fact, a number of our tank inhabitants need iodine- most crustaceans have a significant demand for the material, and a number of fish can develop goiter in captivity from the lack of iodine- African Rift Lake fish seem especially prone to this. The often-discussed toxicity of iodine could be considered urban myth #1.
Salt, sodium chloride, is hydroscopic- exposed to air of more than Sahara-at-midday humidity, it will pick up moisture from the air on the surfaces of the individual crystals, which melt at the surface and cement themselves together- in short, they clump. The salt shaker does not work with clumpy salt, so additives are used to block the clumping. Arrowroot is common for this purpose, but others are possible. Again, as with iodine, quantities are small (but larger than with iodine), and are food-safe and fish-safe
Kosher salt is commonly suggested as an alternative to table salt, as it does not have iodine added. This of course is a response to salt myth #1. Others gasp in horror at this suggestion, as kosher salt may have yellow prussiate of soda (the sodium salt of prussic acid, a ferro- or ferricyanide) as its anti-caking agent. Horrors! That is a cyanide compound! You are sending your fish to the gas chamber and it will kill them instantly! Horsefeathers. Once again, the quantity is tiny, food-safe, and the fish would be pickled in brine long before potentially toxicity could be reached. Salt urban myth #2 down.

There is a definitive answer, its in the long proven research/science i just posted in my last post- this is school textbook stuff and has been known about for decades etc.
If you disagree with anything i say, tell me exactly and give me proof/evidence that backs up your claims, otherwise (no offense intended), i will assume you are just saying stuff which other people have advised you to do, but which actually has no scientific/factual proof that is good to do etc.

PacKRaT;1155503; said:I've read and been following this post for about three days, today is the first day the poll has actually come out of a tie: the no-salt people are in majority right now. Honestly, it seems all the arguments for the use of salt are largely anecdotal, such as my own case, the fish "seem" to feel better, "appear" to have bright colors, and all the arguments against the use of salt are based on research. Although never one to discredit large amounts of anecdotal evidence, such as the case we have here, I can't help but notice that the salt using people fall into the same sort of statistical curve as people on a placebo drug, the "placebo affect" affects around fifty percent of patients in the described fashion. So, I am going to drastically reduce if not eliminate the salt in all my tanks, except maybe my malawi tank, which will get MUCH less salt than before, and I will moniter my fish and water conditions. Thank everyone for taking the time to vote, post opinion, or provide research material. Intelligent feedback like this is what makes MFK one of a kind!
