Can You Use Distilled Water In A Tropical Fish Tank
If you do use mineral water leave it to stand overnight first with an aquarium antibiotic added as bacteria can grow in it after bottling.
Can you use distilled water in a tropical fish tank. Distilled water has essentially no minerals in it. Not only you run the risk of having industrial pollution in the water but there are also potential fish parasites and diseases of the wild. Minerals such as iron and calcium help the fish thrive. Yes it will have some dust in it and maybe some fumes and air pollution in it.
However most aquarium hobbyists are against the use of such water. In addition because fish have semi permeable membranes fish can experience deadly trauma in pure distilled water. That dust also lands in the aquarium. We do not recommend this source of water.
When acetic acid combines with oxygen in the water it converts to carbon dioxide water and bicarbonate. It is distilled water condensed directly out of the air. It seems natural to use it since there are fish in them. So your fish have already been exposed to those things.
The reason you can top off your tank with pure distilled water is that you do not break the mineral balance of your fish tank this way. The increase in carbon dioxide reduces the ph of the aquarium water. Topping off evaporation water losses. Fish tanks should not be filled with distilled water because the minerals are removed from it.
Air pollution also gets in with the oxygen the fish breath. If you add soft mineral water to your aquarium you should do so very slowly mixing it with other water aiming to stabilise the water hardness at a lower level without rapidly changing the ph. Found on the shelf of your local grocery store you can pick up a gallon of distilled water for under a dollar. Commercially distilled white vinegar often 5 percent acetic acid has a ph of 2 4 and can be used to lower the ph in salt water aquariums.
The only downside to distilled water is that it s not practical for larger tanks. You can regularly add some distilled water into your fish tank to compensate for the volume lost through evaporation. You can use distilled water in your fish tank for. While distilled water is darn cheap you ll need an awful lot of it to fill a 50 gallon tank.
