SpiroPure 4-Stage Portable RO with DI Filter for Aquarium Systems

The SpiroPure 4-stage countertop reverse osmosis water filtration system is a versatile and portable water filter that combines four filtration stages. These stages include sediment, carbon block, reverse osmosis (RO), and color-changing mixed-bed deionization (DI). This process effectively removes most impurities, resulting in water that has very low Total Dissolved Solids (TDS). As a result, this water filter is ideal for aquarium RO, CPAP machines, humidifiers, spot-free cleaning (cars, windows, glass, etc) cleaning of transparent surfaces like glass and more.

The SpiroPure filtration system is compact and can be easily set up on your countertop or mounted on the wall. This makes it ideal for apartments with aquarium RO systems or any other space where filtration is needed. It comes with pre-installed, quick-connect fittings and two faucet adaptors that fit most standard faucets and hoses. This product delivers highly purified water, making it ideal for a system like an RO/DI aquarium.

Four-Stage Water Filtration System

Each stage is integral to removing impurities, chemicals, and contaminants from your water. Here’s an overview of each stage:

• Stage 1: The 25-micron sediment filter uses premium polypropylene media to capture dirt, rust, and particles to protect the RO system.
• Stage 2: The coconut shell carbon filter reduces chlorine and harmful chemicals, protecting the RO membrane.
• Stage 3: This stage is essential for aquarium RO systems as it filters out TDS, making the water safe for fish and other marine creatures. The RO membrane filters over 1,000 impurities and reduces TDS to 0.0001 micron for high-flow filtration.
• Stage 4: The DI filter removes ions like sodium and copper, with mixed bed resin that changes color from green to purple when it’s time to replace the cartridge.

I have the SP-RO400AQD RO/DI filter system and used a TDS meter. After the first two stages (sediment and carbon) the PPM of the water rises, and after the RO stage, it drops as expected. But then after the final DI stage, the PPM rises once more. Is the filter system defective?

PPM is a measurement of the TDS (total dissolved solids) inside of the water. Sediment filters are designed to remove large sediment particles, and carbon filters absorb chemical impurities from water (such as chlorine), and are not designed to filter or reduce TDS at all. In fact, a new carbon filter will increase the PPM of TDS in water as it sheds carbon fines, but this should reduce after a couple of days of use. This is why it is recommended that you flush a new carbon filter, particularly if it is before an RO or DI cartridge as it can cause premature fouling of the RO or DI media.

RO membranes, however, are designed to reduce TDS from water, and TDS meters are designed specifically to measure TDS reduction after more in-depth filtration like that provided by RO membranes. Deionization (DI) can then provide further reduction of TDS from water. To see the desired results, we recommend using the filter system without the DI cartridge for a few days when first using the system or after replacing the carbon filter to ensure the carbon fines are gone. After that, reintroducing the DI cartridge should reduce the amount of TDS even further after the RO membrane filtration.
