Every reef tank starts with a choice: build your water from a perfectly clean foundation, or try to fight against whatever comes out of the tap. Chlorine, chloramine, copper, silica, nitrate, phosphate, and hundreds of other dissolved solids ride into your system long before salt, rock, or coral. Over time, they accumulate, fuel nuisance algae, irritate sensitive invertebrates, and make stable chemistry much harder than it needs to be.
Trace Zero is our answer to that problem—a precision water filtration line designed for demanding applications, including reef aquariums, aquaculture systems, and other advanced purification setups. While Trace Zero is a dedicated water filtration brand (not an aquarium company), its high-performance cartridges and membranes are perfectly suited to producing the kind of RO/DI water that modern reef systems depend on. The focus is simple: deliver consistent, reliable purification that strips out impurities, supports stable water chemistry, and gives your reef a truly pure starting point.
Why RO/DI Water Beats Tap Water for Reef Aquariums
Municipal tap water is treated with human use in mind, but reef aquariums are far more sensitive than we are. Common tap water issues include:
- Chlorine and chloramine – harsh oxidizers that damage gills, slime coats, and beneficial bacteria.
- Heavy metals – copper, lead, zinc, and others that can be toxic to invertebrates even at very low levels.
- Silicate, nitrate, and phosphate – fuel for diatoms, hair algae, cyanobacteria, and other nuisance growth.
- Unpredictable TDS – seasonal changes, city work, and source shifts mean your tap water is never exactly the same twice.
Water conditioners can neutralize chlorine and chloramine, but they don’t remove everything else. Those extra ions and contaminants get trapped in your rock and sand, slowly shifting your water chemistry away from natural seawater and giving pests a constant food source.
RO/DI water flips that script. A properly designed RO/DI system strips almost everything out, giving you a nearly blank canvas. From there, you decide what goes into your tank—salt mix, trace additives, nutrient levels—not whatever your municipal supply happens to deliver that week.
The Trace Zero Philosophy: Purity, Consistency, Confidence
Trace Zero is built around a simple idea: if your base water is rock-solid, everything else in reefkeeping becomes easier. Stable calcium and alkalinity, predictable nutrient control, and responsive dosing all depend on starting with water that doesn’t move the goalposts.
That’s why we use Trace Zero filters on our own coral farm and for all RO/DI water sold in store. The same cartridges, membranes, and resin you can buy under the Trace Zero label are what we rely on every day to keep our systems stable.
Our in-store RO/DI water is filtered through Trace Zero 1 µm sediment and carbon cartridges, a high-rejection RO membrane, and colour-changing mixed-bed DI resin to deliver consistently clean, low-TDS source water. It’s ideal for mixing salt, water changes, and evaporation top-off in reef systems.
- In-store only – available exclusively for local pickup at New Dawn Aquaculture.
- Bring your own containers – we’ll fill them for you on-site.
- Made with Trace Zero filtration – the same setup we trust on our coral farm.
The Trace Zero Filtration Stages
A high-performance RO/DI system works like a relay race. Each stage takes on a specific job, protects the next component, and finishes by delivering genuinely pure water. Trace Zero is built around that staged approach, with carefully matched micron ratings and capacities.
Stage 1: Trace Zero 1 µm Sediment Filter – Fine Mechanical Protection
The first line of defense in any RO/DI system is the sediment filter. It traps rust, sand, silt, and other particulates before they can clog the carbon block or damage the membrane.
The Trace Zero 1 µm Sediment Filter Cartridge is a depth-type, melt-blown polypropylene filter designed to remove fine particulates from water before it reaches sensitive filtration or treatment systems.
- 1 µm nominal rating for fine sediment removal.
- High dirt-holding capacity for extended service life.
- Resistant to chemicals and bacterial growth.
- Constructed from food-grade melt-blown polypropylene.
- Compatible with most standard 10" filter housings.
- Ideal for reef and aquaculture source water filtration.
Specifications:
- Size: 10" x 2.5"
- Material: Food-grade melt-blown polypropylene
- Filter Type: Depth sediment (spun polypropylene)
- Micron Rating: 1 µm nominal
- Applications: Potable water, reef aquarium source water, aquaculture systems
Stage 2: Trace Zero 1 µm Carbon Block – Chlorine and Chloramine Control
Next, water passes through a high-density carbon block. Its job is to reduce chlorine, chloramine, and many organic contaminants that would otherwise damage the RO membrane and irritate livestock.
The Trace Zero 1 µm Carbon Block Filter Cartridge is a high-quality activated carbon cartridge designed to remove chlorine, taste, and odour while improving the overall clarity and quality of water.
- Removes chlorine, taste, and odour.
- Improves colour, smell, and clarity of water.
- Removes sediment and organic contaminants.
- Protects RO membranes and downstream filters.
- Constructed from food-grade coconut shell activated carbon.

Stage 3: Trace Zero RO Membrane – High-Rejection Options for Any System
The reverse osmosis membrane is where the heavy lifting happens. Under pressure, water is forced through a semi-permeable membrane that rejects the vast majority of dissolved solids—metals, hardness, nitrate, phosphate, and more.
The Trace Zero Reverse Osmosis Membrane is engineered for high efficiency and long service life in reef, aquaculture, and drinking water systems.
- High salt rejection rate of 97.5% or greater.
- Available in 75 GPD, 100 GPD, and 150 GPD capacities.

- Available Models: 75, 100, 150 GPD
- Applications: Reverse osmosis filtration for reef, aquaculture, and drinking water systems
Stage 4: Trace Zero Colour-Changing Mixed Bed DI Resin – The Final Polish
Even after RO, a small amount of dissolved solids can slip through. For reef systems, we want those last few ppm gone. That’s where deionization comes in.
The Trace Zero Colour Changing Mixed Bed DI Resin produces ultra-pure, zero-TDS water for reef, aquaculture, and laboratory use. This high-capacity ion exchange blend removes the final traces of dissolved solids after RO filtration.
- Delivers 0 TDS water for reef, aquaculture, and laboratory applications.

How Often Should You Change Your Filters?
Exact replacement timing depends on your tap water quality, usage, and system size, but these general guidelines are a good starting point:
- Sediment filter – Replace when it shows significant discoloration or when you notice pressure drop across the prefilters.
- Carbon block – Plan for roughly 6 months of use in many setups, or sooner if you have high chlorine/chloramine levels.
- RO membrane – Monitor the TDS before and after the membrane. When rejection drops noticeably and DI is working harder than normal, it may be time for a new membrane.
- DI resin – Replace once the colour-change zone reaches the bottom of the canister or when product water TDS rises above ~1–2 ppm.
Staying ahead of filter exhaustion protects your livestock and your equipment. It also keeps your salt mix, trace additives, and dosing strategies consistent, because you’re always starting from the same ultra-pure baseline.
Who Trace Zero Is For
Trace Zero is built for anyone who treats water quality as a non-negotiable—and that absolutely includes reefkeepers.
- Reef hobbyists who want fewer surprises and more control over their chemistry.
- Coral farmers and advanced aquarists who demand consistent, repeatable results from batch to batch.
- New reefers who would rather solve tap water issues once with RO/DI than chase algae and instability for months.
Whether you run a small mixed reef or a full-scale coral farm, the goal is the same: remove as many unknowns as possible from your water. Trace Zero exists to make that simple, consistent, and repeatable.
