A good example of fish that is highly susceptible to such trauma is the betta fish.
Can you use distilled water in a saltwater fish tank. You will find that over time a ro di unit will pay for itself and make life easier for you. Fish need water that s rich in these vital elements for optimal health. While distilled water is darn cheap you ll need an awful lot of it to fill a 50 gallon tank. When i say minerals i mean mainly magnesium calcium and iron among many others.
The reason for that is the distilled water s lack of minerals. You should not use distilled water for water changes in your fish tank. Another reason why you shouldn t solely use distilled water in your saltwater aquarium is that it affects your fish s neural health. Just like with the previous pure water sources you must remineralize distilled water before adding it to your tank.
The only downside to distilled water is that it s not practical for larger tanks. They possess a selectively permeable membrane which may lead to a trauma caused by osmosis when placed in distilled water. You can even use the supplements in saltwater tanks. The water doesn t have the impurities but it doesn t have the minerals either.
Although you will need much more. You can but personally i would really recommend rodi there was a post on here a while back where a guy did a direct comparison between distilled and rodi and the distilled tank was covered with brown algae in 3 days and when compared with rodi he had barely any algae after 7 days. Funny that they only have 3 gallons yes you can use distilled water. Distilled water is excellent for a fish tank as long as you take some extra steps.
Fish need ions or charged particles present in salts for transmitting signals through their nervous system. Fish can adapt to gradual changes in ph but fluctuating levels can be detrimental for them.
