RO Water and pH Basics

RO water is often used in hydroponic systems because it is purified, free of contaminants and easy to use. However, one of the biggest factors to consider when using RO water is its pH level. Understanding pH is essential for any hydroponic grower because it affects how easily nutrients can be absorbed by plants.

The pH level of RO water can vary depending on the environment it is stored in and the source of the water. Generally, RO water has a pH level of around 0, which is neutral.

However, pH fluctuations can occur because RO water has no buffering capacity, so it is important to monitor pH levels regularly and adjust if necessary. For optimal plant growth, the ideal pH range is between 5 and

Keeping the pH within this range ensures that nutrients are properly absorbed by the plants. Using pH meters and pH testing kits is an effective way to monitor and adjust pH levels in hydroponic systems.

What is pH

pH, RO water When we talk about RO water, one of the things that often comes up is pH. But, what exactly is pH? pH is a measure of the acidity or basicity of a solution. It is measured on a scale from 0 to 14, with 7 being neutral.

Solutions with a pH less than 7 are considered acidic and solutions with a pH greater than 7 are considered basic. RO water, which is produced through the process of reverse osmosis, typically has a pH between 5 and This is due to the removal of minerals and other substances that can affect the water’s pH.

While this pH range is generally considered safe to drink, some people prefer their water to be slightly more alkaline for various health reasons. In such cases, pH can be adjusted using various methods such as adding alkaline minerals or using an alkaline water machine.

Why pH Matters for Aquariums with RO Water

RO Water and pH If you have an aquarium, then you probably know how vital pH is for the survival of your aquatic pets.
