Using Salt For Freshwater Aquarium Fish - Petcha

Non-iodized table salt is generally recommended for use in freshwater aquariums.

Maintaining and cleaning freshwater aquarium is fairly easy. All you need to do is regularly check the color and temperature of the water, feed your fish with food you buy from pet stores, and clean the fish tank regularly to ensure healthy and happy living conditions inside your freshwater fish tank. With saltwater aquarium, however, special attention is needed in maintaining the nitrate cycle of the fish tank, salinity of the water, as well as the temperature and filtration process.
Some Suggested Salt Sources for when salt is used in a freshwater aquarium:

As you can see, a saltwater aquarium requires some additional and some additional equipment not found on the freshwater side of the hobby. You'll need to invest in a good quality protein skimmer and some good quality live rock. Live rock is important from a biological filter perspective and if you're using live rock you don't have to use an external filter on the tank. Let the remove the dissolved wastes. The external mechanical may actually become a source of if not cleaned often enough since the power filter just traps waste. The protein skimmer on the other hand actually removes the dissolved organics from the water. There’s no need to use any salt. Salt should only be used occasional in freshwater aquariums and usually only to treat for illness.

Freshwater, as in rivers and lakes, does not have appreciable salt content in nature. Most of the plants that we see in an aquarium come from such habitats. As these plants have evolved in freshwater, appreciable amount of salt and/or salty water must be a foreign condition to which a plant has to adapt if it can. Let us examine what salt would cause.
I have come across the comments of several aquarists saying that they just cannot grow even the easiest of aquarium plant. When I read such comments it comes into my mind that ‘1 teaspoon per 10 gallon’ salt addition advice. Salt does not evaporate from the aquarium once it is added. More salt with water changes and topping up, if unregulated will simply increase the salt content to a level where it shall make it hard for freshwater plants to survive.We know that higher amount of soluble solid content increases the internal pressure in the water, demonstration of osmosis in physics have shown how water with lesser amount of solids in solution tends to equalize by escaping through a semi-permeable membrane into a more concentrated solution on the other side. The outer skin of an aquatic plant is semi-permeable. So when we add salt to the freshwater aquarium in any appreciable quantity, there is a chance that a plant will loose its internal water to its surrounding. In other words the plant will wilt.The practice of adding salt (a.k.a. Sodium Chloride, rock salt, table salt, solar salt, aquarium salt) to freshwater aquariums has been around almost as long as the hobby. There are several reasons why hobbyists add salt to the aquarium, stress reduction, medicating, adding hardness, and for fish commonly found in brackish water. It has become a common practice for employees of big box stores to tell all of their freshwater customers to add a teaspoon of salt per 10 gallons (38 l). This is not a practice most advanced hobbyist partake in, nor one recommended. Before you add salt to a freshwater aquarium, you should understand why you are doing so, and any possible side effects.So next time those of you who find it hard to keep plants in your aquariums, try your hand at planted freshwater aquarium, go lightly with salt, and see how easy it is to grow plants. A sand and gravel substrate to anchor the plant, and a little light about 1.5 to 2 watts per gallon and you will enjoy the beauty of a planted aquarium and your fish too will thank you for it. Zeolite is often used in aquariums to remove ammonium/ammonia from solution. When salt is added to the aquarium it prevents the mineral from removing the ammonium/ammonia. Therefore zeolite is only effective in freshwater. Zeolite can be recharged by soaking it in saltwater. When soaked in saltwater it exchanges the ammonium/ammonia with salt.
