How to Use Viva Blu Phosphate Remover

1. Test the phosphate level using a test strip or kit.

2. Calculate dosage:
    – For phosphate levels up to 1,000 ppb (parts per billion):
     Add 250 mL per 50,000L of water
    – For higher levels (1,000–2,500 ppb):
     Use up to 500 mL per 50,000L

3. Pour directly into the skimmer box while the system is running.

4. Run the filtration for 24 hours to ensure complete circulation.

5. Backwash/clean filter after 48 hours if water appears cloudy—this is normal as phosphates are bound and filtered out.

6. Retest and repeat if levels remain above 100 ppb.

Tip: Use monthly to prevent phosphate build-up and keep your pool algae-free all season long.

Applications & Use Cases

• Residential swimming pools (chlorinated and saltwater) — Ongoing phosphate control to suppress algae food source, particularly in pools surrounded by vegetation, lawn areas, or subject to fertiliser runoff
• Commercial and public swimming pools — Routine phosphate management to reduce chlorine demand, improve water clarity, and maintain compliance with public health guidelines
• Spa pools and swim spas — Phosphate elimination in small-volume, high-bather-load water where phosphate accumulation accelerates rapidly
• Outdoor pools subject to high environmental phosphate load — Areas with heavy leaf litter, bird activity, garden fertiliser application, or stormwater intrusion
• Pools with persistent or recurrent algae blooms — Phosphate removal as part of an integrated algae management programme, used in conjunction with appropriate sanitiser adjustment and algaecide treatment
• New pool water commissioning — Establishing low phosphate baseline (<200 µg/L as PO₄) before initiating regular sanitiser programme
• Pools transitioning from freshwater to saltwater chlorination — Clearing elevated phosphate load prior to salt chlorinator installation to protect cell efficiency
• Water features and ornamental ponds — Phosphate control in decorative water bodies where algae growth creates maintenance and aesthetic problems
• Pre-treatment prior to salt chlorinator servicing — Reducing phosphate-induced scale and biofilm load on electrolytic cell plates

Dosing Rates & Guidelines

Dosing rates are based on Australian industry practice and SPASA guidelines. All rates assume product at approximately 7–12% w/v active lanthanum chloride. Measure phosphate level using a calibrated photometric test kit or test strips before dosing. Target post-treatment phosphate level: <200 µg/L as PO₄ (ideally <100 µg/L).

Application	Initial / Elevated Phosphate Dose	Maintenance Dose	Units	Notes
Residential pool — low phosphate (<500 µg/L PO₄)	150–200	75–100	mL per 50,000 L pool volume	Apply monthly or as testing indicates. Backwash filter 24–48 hours after treatment to remove precipitate.
Residential pool — moderate phosphate (500–1,000 µg/L PO₄)	300–400	150–200	mL per 50,000 L pool volume	May require two-stage treatment 48 hours apart. Monitor turbidity and filter pressure.
Residential pool — high phosphate (1,000–3,000 µg/L PO₄)	500–600	200–300	mL per 50,000 L pool volume	Treat in stages of no more than 600 mL per 50,000 L per dose to avoid excessive turbidity. Backwash between doses.
Residential pool — very high phosphate (>3,000 µg/L PO₄)	Up to 1,000	300–400	mL per 50,000 L pool volume	Consult pool technician. Investigate and address source of phosphate contamination before treating.
Spa pool / swim spa	10–20	5–10	mL per 1,000 L water volume	Dose after each significant bather load or weekly as maintenance. Cartridge filter rinse required 24 hours post-treatment.
Commercial / public pool	As per residential rate scaled to volume	As per residential rate scaled to volume	mL per 50,000 L	Continuous or weekly dosing via chemical dosing pump recommended. Verify phosphate levels twice weekly. Comply with relevant state public health pool regulations.
Water feature / ornamental pond	10–20	5–10	mL per 1,000 L water volume	Ensure adequate filtration is operating. Not for use in ponds containing aquatic animals without specialist advice — lanthanum compounds may be harmful to fish and invertebrates at elevated concentrations.

Dosing rates are indicative only. Actual dose required is determined by measured phosphate concentration, water volume, and filtration efficiency. Site-specific conditions may require adjustment. Always retest 24–48 hours post-treatment and repeat dose if phosphate remains above 200 µg/L.

Dilution Instructions

Viva Blu Phosphate Remover is a ready-to-use liquid treatment for direct application in most residential and commercial pool applications. Predilution is generally not required and is not recommended for high-concentration treatments. The following instructions apply to standard pool dosing and to situations where dilution is used to ensure even distribution in small volumes.

1. Read the SDS before handling. Ensure appropriate PPE is worn prior to opening the container (see Safety & Handling section below).
2. Test pool water phosphate level using a calibrated photometric test kit before dosing. Record the result and calculate the required dose volume based on the dosing rate table above and your pool volume.
3. Ensure pool circulation system is running at full flow rate. Phosphate remover must be distributed throughout the pool volume to react effectively.
4. For direct application (standard method): Measure the required dose volume using a dedicated chemical measuring jug. Pour the product slowly and directly into the pool water in front of a return jet or in multiple locations around the pool perimeter while walking. Do not pour in a single concentrated stream into one location.
5. For dilution prior to application (recommended for spa pools, small water features, or to improve distribution in large commercial pools): Add the measured dose of phosphate remover to a clean plastic bucket containing at least 10 parts of pool water. Stir gently. Apply the diluted solution evenly around the pool. Always add the product to water — do not add water to the concentrated product in the product container.
6. Do not premix with other pool chemicals. Never add phosphate remover to the same bucket as chlorine, pH adjusters, algaecides, or flocculants. Dose phosphate remover separately, at least 30 minutes apart from other chemical additions.
7. Allow circulation to run for a minimum of 4 hours following treatment to ensure complete mixing and precipitation reaction.
8. A temporary milky or cloudy appearance is normal and indicates the lanthanum phosphate precipitation reaction is occurring. Clarity will return as the filter captures the precipitate, typically within 12–48 hours.
9. Backwash sand or DE filter, or rinse/replace cartridge filter element, 24–48 hours after treatment to remove accumulated lanthanum phosphate precipitate from the filter media. Failure to backwash will reduce filter efficiency and may return phosphates to the water column.
10. Retest phosphate level 24–48 hours after treatment. If phosphate remains above 200 µg/L, repeat the dose and backwash cycle.

Chemical Compatibility

Compatible With

• Chlorine sanitisers (liquid sodium hypochlorite, granular calcium hypochlorite, trichlor, dichlor) — dose separately with minimum 30-minute interval
