What Water Can I Use in a Planted Tank?

If you have decided to start a planted tank, one of the essential aspects that you need to take care of is the water. The water in your tank is not only going to be the living environment of your plants but also the homes of your aquatic pets. So, what kind of water is suitable for your planted tank? In this article, we will discuss the types of water that you can use and the advantages and disadvantages of each.

Tap Water

In most households, tap water is a readily available source of water. While it may seem like an easy solution, tap water isn't always the best option for a planted tank. Most municipal water supplies contain trace amounts of chlorine or chloramine to disinfect the water. While this is harmless to humans, it can be detrimental to your plants and aquatic creatures.

The best way to use tap water for your planted tank is to treat it first with a water conditioner. The conditioner neutralizes the chlorine and chloramine present in the water, making it safe for your fish and plants. You may also consider running the tap water through a water filtration system before using it in your tank.

Distilled Water

Distilled water is an option for a planted tank, but it is not the best one. Distilled water is completely sterile with no minerals, which is not ideal for a planted tank. Your plants need minerals like calcium and magnesium to thrive, and distilled water will not provide them with these necessary elements.

You can use distilled water if you add the necessary minerals using fertilizers or substrate such as crushed coral. However, this can be quite challenging to manage, and you may find it easier to explore other water options.

Spring Water

Spring water is an excellent alternative to tap water in a planted tank. It is sourced naturally from underground rivers and springs and does not contain any harmful chemicals. Spring water also contains natural minerals and trace elements that your plants can use to thrive. However, spring water can be quite costly, depending on where you live, and may not be a viable option for everyone.

RO (Reverse Osmosis) Water

RO water is a fantastic choice for a planted tank. Reverse osmosis is a process where water is forced through a membrane to remove impurities, minerals, and trace elements. The result is pure water that is free of any contaminants, minerals, or trace elements. This makes it ideal for planted tanks because you can add minerals back in through fertilizers or substrate.

RO water can be quite expensive, and you may need to purchase an RO system for your home. However, many fish stores and pet stores may carry RO water and will refill your containers for a nominal fee.

Conclusion

Choosing the right water for your planted tank is essential for the health and success of your aquatic pets and plants. While tap water may be a readily available and cost-effective solution, it is not always the best option. Distilled, spring, and RO water are all viable alternatives, each with its own advantages and disadvantages. Choose the water that meets your needs and budget, and remember to always treat it before adding it to your planted tank.
