NeoPhos - 250 ml

Brightwell Aquatics NeoPhos is a balanced source of phosphorus formulated for reef aquariums in which phosphate is insufficient relative to nitrate and organic carbon.

Maintaining an appropriate balance of carbon, nitrogen and phosphorus allows beneficial microorganisms to process organic waste effectively. When phosphorus becomes limited, microbial nutrient uptake may slow or stop while nitrate and other nutrients remain elevated.

NeoPhos is intended for controlled dosing based on accurate phosphate and nitrate testing. It may be used with MicroBacter7, Reef BioFuel, Katalyst and NeoNitro as part of an advanced nutrient-management system.

• Supplies phosphorus to phosphorus-limited reef aquariums
• Helps maintain balanced carbon, nitrogen and phosphorus availability
• Supports natural microbial nutrient uptake
• Helps prevent phosphate from reaching or remaining at undetectable levels
• Can support the biological reduction of ammonia, nitrite and nitrate when used within a balanced nutrient-management system
• Supports zooxanthellae and zooxanthellate reef organisms by maintaining nutrient availability
• May be used with MicroBacter7, Reef BioFuel, Katalyst and NeoNitro
• Formulated for advanced low-nutrient reef aquarium management

Shake well before every use. Do not overdose.

The manufacturer has produced NeoPhos in more than one concentration. Always follow the dosage and number of gallons treated printed on the specific bottle being used.

1. Test phosphate and nitrate with accurate test kits or calibrated digital testing devices.
2. Confirm that phosphate is below the desired level or below the detection limit of the testing method.
3. Dose NeoPhos according to the bottle directions to reach approximately 0.02 ppm phosphate.
4. Wait 24 hours, then retest phosphate and nitrate.
5. Continue dosing only as required to maintain approximately 0.01–0.02 ppm phosphate while nitrate decreases toward the desired range.
6. Once the desired nutrient balance is reached, establish a maintenance dose based on regular testing and the aquarium’s actual nutrient consumption.

Brightwell suggests a nitrate range of approximately 3–5 ppm when following this nutrient-management approach.

Results may be most significant when MicroBacter7 is dosed daily or every other day.

1 × Brightwell Aquatics NeoPhos, 250 ml

No installation is required.

Before dosing:
1. Calculate the aquarium’s actual total water volume.
2. Test both phosphate and nitrate with accurate equipment.
3. Confirm that the aquarium is phosphorus-limited.
4. Check the dosage strength and number of gallons treated on the bottle.
5. Shake the bottle thoroughly.
6. Measure the required dose carefully.
7. Wait 24 hours after dosing before retesting and making another adjustment.

NeoPhos may be added through a properly calibrated dosing pump once the aquarium’s regular phosphorus demand has been established. Continue frequent testing because nutrient consumption can change over time.

Keep out of reach of children. Not for human consumption.

Do not overdose. Use only after testing phosphate and nitrate with accurate equipment.

Specific storage conditions are not stated by the manufacturer.

Phosphate remains undetectable:
Confirm the test kit’s detection range and verify the aquarium’s actual water volume. Follow the dosage strength printed on the bottle, wait 24 hours and retest before making another adjustment.

Phosphate remains elevated after dosing:
Stop adding NeoPhos and continue testing. A prolonged phosphate increase without a corresponding reduction in nitrate may indicate that the aquarium is carbon-limited.

Nitrate and phosphate remain unchanged:
The system may be carbon-limited. Brightwell recommends adding Reef BioFuel at 1 ml per 25 US gallons, waiting 24 hours and retesting. Follow all directions for the additional product.

Nitrate decreases while phosphate also falls:
Continue carefully dosing NeoPhos as required to maintain approximately 0.01–0.02 ppm phosphate until nitrate reaches the desired range.

The dosage information found online differs from the bottle:
Follow the dosage and number of gallons treated printed on the bottle. The manufacturer states that more than one NeoPhos concentration has been sold.

Corals appear pale in an ultra-low-nutrient aquarium:
Test both phosphate and nitrate. Insufficient nutrient availability may contribute to bleaching or tissue degradation, but do not add NeoPhos unless testing confirms that phosphorus is limited.

What does NeoPhos do?
NeoPhos supplies phosphorus to reef aquariums in which phosphate is insufficient relative to nitrate and organic carbon.

Is NeoPhos a phosphate remover?
No. It adds a controlled source of phosphorus and is intended for aquariums with phosphate below the desired concentration.

Who should use NeoPhos?
The manufacturer recommends it for advanced reef aquarists maintaining low-nutrient or ultra-low-nutrient reef systems.

Should NeoPhos be used without testing?
No. Test phosphate and nitrate accurately before dosing and again 24 hours after each adjustment.

What phosphate concentration does Brightwell recommend?
The manufacturer’s instructions initially target approximately 0.02 ppm, followed by maintenance around 0.01–0.02 ppm within its nutrient-management method.

How much NeoPhos should I add?
Follow the dosage printed on the specific bottle. More than one product concentration has been sold, so a universal dosage should not be assumed.

Can NeoPhos lower nitrate?
It does not directly remove nitrate. Supplying phosphorus can support microbial nitrogen uptake when phosphorus is the limiting nutrient and adequate carbon is available.

Can it be used with MicroBacter7?
Yes. Brightwell states that results may be most significant when MicroBacter7 is dosed daily or every other day.

What if phosphate rises but nitrate does not decrease?
The aquarium may be carbon-limited. Stop adding unnecessary NeoPhos, retest and follow Brightwell’s guidance regarding Reef BioFuel or Katalyst.

Can NeoPhos be used with NeoNitro?
Yes. Both products may be used within a carefully tested nutrient-management programme to achieve the desired phosphate and nitrate concentrations.
