How to Choose the Right RODI System for Your Reef Tank

Reefers are primarily water keepers. After all, what destroys aquatic life the fastest? Water impurities and pollution. Besides, without a proper balancing of water nutrients, keeping fish and other inhabitants will not be possible.

As humans rely on air quality for life, the quality of water in the aquarium directly impacts the growth, coloration, and overall ecosystem of your reef inhabitants.

In this article, we will discuss how you can choose a water source for your fish tank. We will go through what a RODI water filter is and useful tips to help choose the right RODI system for your tank.

Let’s start by looking at what an RODI water system is.

What is an RODI Water Filter?

RODI stands for.

RO = Reverse Osmosis

DI = De-Ionisation

Here’s the real deal

The quality of water you choose in your fish tank is a very important factor in having a successful system. Whether you’re building a freshwater tank, a fish-only tank, or a saltwater aquarium, providing reverse osmosis deionized water will help you keep a healthy system.

The major function of RODI water in an aquarium is because, unlike tap water, it’s free from impurities like algae blooms.

This water system is capable of extracting almost all common tap water impurities.

Choosing the Right RODI System for Your Reef Tank

Simple Tips

  1. Have a professional test your water or see what other local aquarium owners are using
  2. Decide on how many stages you think you will need based on Step 1
  3. Research the different types of systems available and choose an ideal variety
  4. Start with the least amount of stages you think you will need, but leave space to add further stages if needs be in the future

A Broader View

There are some factors to consider before you purchase a reverse osmosis system for your fish tank. Keep in mind that all RODI systems are not the same, and will have differing features. And these will determine whether you spend more or less on maintenance in the future.

What then are the factors to consider?

STAGES

The number of stages in an RODI system will determine the quality of the output of the filter. For instance, a RODI system with two deionization filters will perform better than one with a single filter.

In addition to showing more strength against dissolved solids in the water, a RODI system with two deionization filters will also help remove excess chlorine from the water systems. Also, using an extra carbon filter can help purify treated municipal water systems.

WASTE WATER RATIO

When an RODI system filters contaminants from your aquarium, it flushes them out with a certain amount of water.

Depending on what you have, a Reverse osmosis system can waste about 4 gаllоnѕ оf water per gallon оf frеѕh wаtеr thеу рrоduсе. So, if you plan to conserve water, ensure you buy a system with a low wastewater output feature.

FINALLY, CONSIDER THE FILTER COST

While the cost of a reliable RODI system might be pricey, its maintenance is also another thing to consider. Moreover, you’ll need to replace carbon filters twice a year over the lifecycle of the RODI system.

When properly maintained, reverse osmosis membranes can work great for about two years. The deionization resin, on the other hand, may need replacement within 3 to 6 times a year.

 

What Are The Benefits of Using RODI Water?

As discussed above, RODI water is clean and safe for your saltwater aquarium. Having deionized water in your tank ensures that your fish and corals are healthy.

When you use RO/DO water, you’re trying to recreate the clean water the fish have in their natural habitat.

Additionally, using RODI water lets you determine the composition of essential elements you add to your fish tank. So, you’ll totally be in charge.
