Oscar Fish Advice Forum: adding salt to oscar tank?? (1/1)
Votes: 79. You don't need to add salt unless you are treating for a sickness, or you have a brackish tank. If your fish ever do get sick, they will be immune to salt.
Bacteria and parasites do not gain resistance to salt like they can with antibiotics. The benefits are many but there are drawbacks to consider. Live plants can be killed if concentrations are too high as well as corydoras and Chinese algae eaters so try to stay at the recommended levels if using in the aquarium. Bottom feeding fish can adjust to a low dose salt level if salt is slowly added over a few days. Avoid dumping all the salt at one time and always pre dissolve the salt before adding especially if the tank has salt sensitive species.
Hi i am in the process of setting an aquariam for goldfish, it has a external fitler and contains 151 liters of water, do i add aquarium salt to the water before any fish are put in the tank or do i put salt in with the fish ? and if so now much would you recommend.

Add Salt to Molly Tank & How much of Mixture? - "Mollies" Fish
My tropical fish dealer told me to add sea salt to my aquarium each time I add about 1/3 new water to the tank, mostly for my puffer fish, the added plus is the other fresh water tropical fish loved it and thrived, I think they are most vibrant in color as well.I used to add a small amount of aquarium salt to my FW tank (since I didn't have crustaceans or nonscaled fish like cats - they are sensitive to salt) because most scaled fish do better with slightly brackish water.
Aquarium salt is the best, and sea salt also excellent. Table salt is not recommended because they add anti-caking agents to it that can be harmful to fish, and they lack other naturally-occuring chloride salts (potassium, magnesium) beyond sodium that fish tend to prefer.That's not entirely true.
I kept African Cichlids for a few years, and they are supposed to have a high Ph...up to 8.0 for the Lake Tanganyika species. I added "salts" to the water to help achieve the higher Ph as well as using a mix of crushed coral and gravel for the bottom of the tank in order to maintain high Ph levels, and to prevent dips and spikes which are hard on the fish.
Some of these fish are extremely colorful, and to me, they are as close to saltwater varieties without having to invest in the extra time and expense a saltwater tank requires. They are technically freshwater fish, though.
Now, I only keep a couple of straggler bottom feeders who have not been given away and have grown fairly large, and I do not add salt to the water.Much has been written about the pro's and con's of adding salt to an aquarium. Some support its use unequivocally, while others condemn it outright. As usual, the truth lies somewhere in the middle.
Why would we want to add salt in the first place? After al, there are a few fish that do not do well with any salt at all in the water. Some fish that do not do well with added salt would include smooth skinned catfish, Corydoras, Tetras, Angelfish, Discus, Loaches and Bettas. There are others as well. High concentrations of salt also are detrimental to planted aquariums.
Some fish that do much better with added salt would include Goldfish, Koi, African Cichlids, and livebearers. Indeed, the secret to keeping healthy, robust Mollys, Platys, Swordtails, and Guppys is to add salt. Many Ichthyologists consider Mollys and Platys to be saltwater fish that have been adapted to freshwater, and not the other way around. Almost all health problems with Mollys disappear when salt is added. Mollys can actually thrive and reproduce readily in straight seawater. Some saltwater aquarists use Mollys as "cycle" fish in their saltwater aquariums. The usual recommended dose is 1 tablespoon of aquarium salt per 5 gallons of water. This does does not seem to harm most plants, but higher doses may.
Some people keep mixed community aquariums to include both Mollys and Tetras, Platys and Corys. I have kept these fish in water with added salt for years, and have never noticed any particular problems to the Corys or Tetras, although they will not readily breed in water with any salt added. Corys and Tetras can best be bred in soft, slightly acid salt-free water, so that may be a factor for you if you wish to keep these particular species for breeding purposes. You may not want to keep Corys and Tetras intended to be bred in community tanks with added salt.
Advantages of added salt include better osmosis balance for the fish (who must maintain a proper internal/external balance of water). Salt also reduces or eliminates nitrite toxicity. In a cycling tank, nitrites can be quite toxic, but not with added salt. Indeed, marine fish are completely free of worries from nitrite toxicity due to the high salt content of seawater. Experiments with nitrite levels as high as 25 ppm cause no problems for saltwater fish. A similar effect can be expected with freshwater fish, although of course we will not be adding salt at the same rate as for saltwater fish. Salt also reduces parasite infestations, since salt interferes with the life cycle of many (or most) external parasites.
