ZOANTHUS LAB – Phosphate Minus 1000 ml: precise phosphate reduction in reef aquariums
Zoanthus Lab Phosphate Minus 1000 ml is a concentrated solution designed to precisely reduce excess phosphates in marine aquariums. Phosphates ( PO4 ) are essential nutrients in small doses, but their accumulation can hinder calcification, promote biological imbalances, and complicate the maintenance of a stable reef tank. Formulated with purified water and pharmaceutical-grade iron(III) chloride , this product guarantees clear, stable, and perfectly measurable action. Free of unnecessary additives, it integrates perfectly into a rigorous management system based on ICP analysis. A reliable, transparent solution designed for discerning aquarists.
- Targeted phosphate reduction after ICP analysis
- Simple, progressive and easily reproducible dosage
- Pure formulation, without unnecessary stabilizers or complexing agents
- Each batch is tested in our laboratory before being sold.

The role of phosphates in reef aquariums
Phosphates are naturally present in very low concentrations in a balanced marine aquarium. They play a role in the metabolism of living organisms, but when they accumulate beyond the desired range, they can inhibit the growth of hard corals, disrupt certain biological balances, and promote the growth of unwanted algae.
In a modern reef tank, phosphates primarily originate from food, organic matter, and some insufficiently pure preparation water. Controlled reduction allows for a more stable environment without abrupt correction, particularly in demanding tanks focused on coral growth and long-term stability.
We offer a full range of products to target the main elements of seawater following ICP analysis or manual testing.
A simple, direct and controlled formulation
The Zoanthus Lab – Phosphate Minus solution is prepared from iron(III) chloride (FeCl 3 ) , dissolved in purified water.
Using pharmaceutical-grade raw materials ensures a clean, homogeneous solution that aligns with rigorous reef monitoring. This formulation is designed to [oaicite:1] for a gradual and measurable reduction {index=1} phosphates, while remaining compatible with precise management based on ICP analysis and regular tank observation.
- ✔ Stable inorganic solution
- ✔ Chelator-free
- ✔ Compatible with progressive reef management
- ✔ Consistent and reproducible results
Concentration and dosage
The solution is formulated according to a precise protocol:
- Recommended dosage: 0.2 mL per 100 L of water
- Effect: decrease of approximately 0.01 mg/L of PO4
- Gradual correction: do not decrease by more than 0.02 mg/L per day
- Practical guideline: 1 mL per 100 L of water reduces approximately 0.05 mg/L of PO4
- Practical formula: mL to be dosed = ΔPO4 (mg/L) × 20 × (volume of the container in L / 100)
Phosphate reduction should always be based on a recent ICP analysis or a reliable measurement. It is recommended to add the solution slowly in an area of strong water movement, ideally pre-diluted, and then monitor the PO4 levels and the overall reaction of the tank. In the case of [oaicite:2] significant correction, it is best to spread out {index=2} additions to avoid a rapid drop.

Usage and storage instructions
Add slowly to a well-circulated area of the aquarium or to the sump. Pre-dilution may be helpful for more even distribution. Shake well before use.
Store away from light, between 15 and 25°C, in a tightly closed container. The protocol also recommends the use of suitable bottles or containers, protected from light, with a recommended shelf life of 6 to 12 months. :contentReference [oaicite:3] {index=3}
- Product intended exclusively for use in aquariums!
- Keep out of reach of children! Do not swallow! Do not ingest.
- Not suitable for animal feed.
- In case of contact with skin or eyes, rinse thoroughly with water.
As with any nutrient corrector, excessive use is unnecessary and can unbalance the water. Regular monitoring via ICP analysis remains the most reliable method for adjusting phosphates sustainably and safely.
