I have sick fish. I thought I'd give all the them a salt bath. (So far I have 3 fish) What is the best salt to use? The expensive 'pond salt' or just plain sea salt. One more question... when measuring I have read referring to using 100 gal of water. How much salt for, say, 5 or 10 gal of water? When searching for these questions I always get info from companies that want to sell me their products. Grrr
From my understanding, the issue of salt dosing is that the ratio of salt to water is based on the overall weight of the salt. I have to look it up every time — I don’t have a recipe off the top of my head —
but they are out there! And if a recipe says to use 100 gallons of water, just do some math to reduce the amount of salt needed. Your weight to volume ratio stays the same (like reducing a recipe meant to serve 100 guests, when you are a family of 4).
Remember this question? Which is heavier: a pound of lead or a pound of feathers? Of course, a pound is a pound, but you have different densities and volumes involved. I am just pulling this off the top of my head, but here’s what I think:
- The expensive pond salt has been formulated in such a way that they know the weight to volume ratio. Since a lot of people don’t have a scale to measure the exact weight, they can “safely” say that xx amount of salt equals xx number of pounds of salt. Makes it easy to figure how much to use. And this salt probably dissolves faster and more evenly. Convenience.
- Other salts, rock salt, sea salt, pool salt are made of larger “crystals” or chunks. They could probably be used (making sure there are no other ingredients mixed in), but it wouldn’t be as easy for you to calculate the weight unless you did use a scale. IOW, a cup of a finer grained salt (like table salt) isn’t going to WEIGH the same as a cup of chunky salt.
- Maybe the expensive pond salt has other, added ingredients, which would raise the price, IDK. Quality control.
- Because if you label it “for ponds,” you’ve created a niche product
