Tip of the Day | RO Filter your Tap Water

We’ve talked about DE-chlorinating your tap water at Aquarium Tip Tank, but this aquarium tip will help make sure that the water you put in your tank is clean and stable.  Fish, corals and invertebrates generally enjoy water conditions that match their natural environment. Well, water from your tap is most likely completely different than the water in your pet fish’s natural environment. The first step to matching natural water conditions is filtering all of the strange chemicals and minerals out of your tap water!

There are several chemicals that are added to municipal tap water in order to help clean the water and make sure that it is drinkable for humans. Just because it is drinkable does not mean that the water chemistry is suitable for your fish! Tap water may also contain several minerals and bacteria that is not harmful humans, but is different than the minerals and nutrients in the natural environment of your fish. Therefore, it is not safe to add unfiltered tap water to any aquarium.

The best ways to filter your tap water is to use a reverse osmosis filter. A reverse osmosis filter basically works by forcing your tap water over a semi-permeable filter membrane that removes those chemicals and minerals and leaves some clean water and some dirty waste water. There are several types of reverse osmosis filters available from the inexpensive, portable filter to the very expensive, installation required reverse osmosis filter.

Remember, when using a reverse osmosis filter you are removing all minerals and chemicals from your tap water. This water is fine to add directly to your aquarium if you are just topping off the evaporated water. However, if you are performing a water change you must add the minerals of your pet fish’s natural water environment. Make sure you use the correct water conditioners or saltwater mixes after you filter your tap water when you are performing a water change.
