🔵 Sal Para Acuario ,Tratamientos Y Baños De Sal Para Nuestros Peces (Acuarios MB)

Sometimes we see our fish scratching themselves against the substrate or rocks, either sporadically or continuously. One cause of this behavior may be the presence of parasites on their skin or gills, causing the itching. Other times, we see them as a result of a fight. Sea salt (iodine-free) can be used in freshwater aquariums as an antiparasitic treatment. Although it is not an antibiotic per se, it does have antiseptic effects, so it also helps heal any wounds or ulcers that may exist. In this case, the dose should be about 2 g/liter. Sea salt changes the osmotic pressure of the water and increases its conductivity, causing the cells of living organisms to dehydrate and shrivel. This change affects non-halophilic bacteria—as is the case with many of the parasites that appear in freshwater aquariums—more than it affects the fish. In this stressful situation, parasites have less chance of survival and die from dehydration. However, the continued use of salt in an aquarium can lead to the development of resistance in some bacteria, which would have the opposite effect. What type of salt can I use? Natural, non-iodized sea salt. Many commercial salts suitable for human consumption come from salt marshes, where the iodine content is 0.14 ppm, while the dissolved concentration in the sea is 0.52 ppm. Therefore, when adding sea salt, we must ensure that it is not iodized or contains anti-caking agents. High iodine concentrations can be toxic and affect the glands that produce hormones. However, a low iodine concentration could cause hyperthyroidism. How much salt should I add? How much salt is in freshwater? The salt concentration in freshwater is below 0.05 grams/liter; above this concentration and up to 3 grams/liter, we have brackish water. Although some of our fish live in hard water, they do not live in brackish water, so we should not maintain the salinity too high. The amount of salt will vary depending on the intended use and the biotope we maintain. The recommended solution is 2 grams/liter of water. However, we must keep in mind that sudden changes in parameters greatly affect and stress fish. Therefore, if we want to achieve a solution of 2 grams/liter, we can add 1 gram per liter of actual water (not the total tank capacity) throughout the day and another 1 g/liter the following day. Salinity isn't one of the parameters we usually measure frequently in our aquariums, so we must be careful with the dosage we add, as it accumulates and can create resistance in bacteria, as happens with the misuse of antibiotics. After seven days, we will perform a larger than usual water change (around 35%) and gradually eliminate the salt from the water with weekly 25% water changes. How does it affect the bacteria in the filter? There are halophilic and non-halophilic bacteria. That is, bacteria that tolerate salt and others that don't. The filter bacteria we are interested in, that is, the nitrifying and nitrisifying bacteria, are halophilic, so they are not affected by increased water salinity. According to some studies, increasing salinity could improve their development, but we shouldn't increase salinity unreasonably, because the bacteria we might want to eliminate could develop resistance that makes the salt ineffective. What is osmosis? By increasing the amount of salt dissolved in water, we are changing the osmotic pressure of the medium. What is this? To put it more simply, we can say that if we have two fluids with different amounts of dissolved salt separated by a semi-permeable membrane (as is the case with cells), the water molecules in the less saline solution will cross said membrane "without energy expenditure" to balance the difference in osmotic pressure, until an isotonic equilibrium is achieved, that is, a situation in which both solutions have the same amount of dissolved salts, and therefore the same osmotic pressure. Fish interact with their external environment through the membranes of their skin cells. This exchange of molecules is essential for their cellular life and occurs "without energy expenditure" since the osmotic pressure of their cells and that of the environment are similar; this is called isotonic equilibrium. When the salinity of the environment changes, the cells will tend to dehydrate or swell, depending on the osmotic difference. If the medium has a higher salinity (hypertonic), its cells will dehydrate and wrinkle since they will leave scars.
