Best, Most Consistent, Trusted Aquarium/Pond Salt From Reputable API Brand
Great aquarium or pond salt. This is the brand I always buy and have been using for decades. Reliable and consistent. Quality never seems to change! I have it on repeat auto ship.

Perfect price; Perfect Size
I've started using a little sea salt with cichlids. I knew they were tolerant to salt levels and was beneficial to them. In fact, with added salt, I was surprised to be greeted with three fry. I'm not saying the salt made them "randy" but I've had more fish in a larger tank and never had any breeding and their life expectancy seemed lower. Now, given that experience, I decided to add salt to my 500 gallon pond with Shubunkin and Fantail Goldfish. Fancy goldfish, less expensive and smaller than koi for my pond size. As you may know, these are hearty fish but not immune from common ailments. Fin rot being common for decorative fish. Since water changes and muck removal are more difficult for an in-ground pond set-up, I have increased to amount of filtration (using filter cleaning and pour-outs as my water changes), increased the substrate sand depth and started adding API pond salt to boost their natural defenses and curb the underlying causes. 4 pounds is just under the recommended amount on the label and way over, by one cup, some others recommend from a web search. I stayed at the lowest recommendation because I use some extravagant marginal plants for Nitrate removal; with their impressive growths losing them would be just as costly as losing 12-to-16-inch adult fish. There are lots of options available from other manufacturers but API though I am wary of "amateur hobbyist" aquatic products, I'm equally warry of over-priced bulk volume venders with no proven record to substantiate their price against their product claims. Captive fish salt is fairly straight forward. So, in sum, I chose API for their price add volume needed against bulk item storage and other products unproven quality. Quality that can't be measured by the number of units sold, 5-star ratings and written reviews from casual hobbyists and patio decorators. No offense. I have too much value invested if you include the lives I've chosen to care for; no matter the "value" you give a fish or a plant against a dog for example. My partner cries the same for the loss of a fish as the loss of a dog. Keep that in mind as you consider my review.

Protect your fish
Don't forget to salt your fish! Ponds, bowls or aquariums. We have skin, fish have scales. But they need a healthy coat of slime on them to prevent illness, fungus or injuries. It's just as important as using chlorine remover. Aquarium salt (not Epsom or table or any other) protects that body slime. It's not visible, but it is necessary for good health. Price is reasonable too

Pond Salt Is a Fish Savior
I used to get expensive fish treatments when my pond fish, including several koi, were looking a little rough. But I found none of them, including treated pond salt, were as good as they claimed, and I lost some fish because of that. After speaking with someone about the issue, they said, “Hey, idiot, get some regular old pond salt.” Couldn’t be happier with the results. It costs much less than the other “cures” I tried and is simple to use. You just need to measure your pond volume and apply as directed. Bonus: it not only keeps my fish healthy, but also helps treat algae and improves water clarity—naturally.

Had to isolate one of my small pond koi yesterday after noticing it just doesn’t seem to come up to the surface for food , I just never seem to see it & I’ve only had it for approx 4 weeks . On closer inspection I found it hiding behind plants & my much larger Koi ganging up on it so I immediately removed & isolated it in a tank with plenty of air stones , Did some research & the symptoms pointed to “Fungus “ . I ordered this salt Last night , it arrived this morning so I immediately gave the Little Koi a 10 minute salt bath before popping it back in isolation . It’s only early days But the Koi has definitely livened up & is attempting to swim around the tank , this is right after the fish had spent the entire time laid on the bottom of the tank since yesterday , not eating , gasping & totally lethargic . If this is the result from just one use I’m very impressed . Will be treating again tomorrow. ( 24 hours apart as instructed) Product arrived with slight leakage but nothing too bad , you get plenty of product for the price too so it will last a while . I’d definitely recommend it .
