Concentrated Phosphate-Binding Solution

Reef Charge PhosLock is a concentrated phosphate-binding solution for reef and marine aquaria. It binds reactive PO4 into a filterable particulate for controlled phosphate reduction when used with mechanical filtration and/or protein skimming.

Use When

  • Phosphate is testing above your target range.
  • You want a controlled, test-guided phosphate reduction without adding organics.
  • Your system has mechanical filtration, filter floss, a filter sock, or protein skimming available to remove the formed particulate.

Directions / Mode d’emploi

DIRECTIONS

Test phosphate before use. Dose into strong flow beside mechanical filtration or a protein-skimmer intake. 1 mL per 25 L (≈6.6 US gal) targets up to 0.606 ppm PO₄ reduction and adds approximately 0.678 ppm chloride. Do not exceed 0.82 mL per 25 L (≈6.6 US gal) in 24 hours or reduce phosphate by more than 0.5 ppm in 24 hours. Measure in 0.1 mL increments. Retest after 24 hours and remove captured particulate.

WARNINGS

Rapid phosphate reduction may stress sensitive corals or invertebrates. Do not overdose.

For aquarium use only. Do not ingest. Avoid contact with eyes and skin. Wash hands after handling. Keep out of reach of children and pets.

MODE D’EMPLOI

Mesurer les phosphates avant l’emploi. Ajouter dans un courant fort près de la filtration mécanique ou de l’aspiration de l’écumeur. 1 mL par 25 L (≈6,6 gal US) vise une réduction maximale de 0,606 ppm de PO₄ et ajoute environ 0,678 ppm de chlorure. Ne pas dépasser 0,82 mL par 25 L (≈6,6 gal US) en 24 heures ni réduire les phosphates de plus de 0,5 ppm en 24 heures. Mesurer par incréments de 0,1 mL. Refaire le test après 24 heures et retirer les particules captées.

AVERTISSEMENTS

Une réduction rapide des phosphates peut stresser les coraux ou invertébrés sensibles. Ne pas surdoser.

Pour aquariums seulement. Ne pas ingérer. Éviter tout contact avec les yeux et la peau. Se laver les mains après manipulation. Tenir hors de la portée des enfants et des animaux.

Phosphate reduction

I approached Phoslock with caution to slowly reduce phosphate ppm . Testing every couple of days it appears the phosphate level is dropping to an acceptable level . Still working on cause of the high phosphor levels . I had originally thought it was my source water (well) however on testing that was not the cause .

Are you going to be making this product in 16OZ Size or in 500 ML Size bottles ?
Asked by Pat Scherf
Answer:

Yes, we’re working on expanding both the Reef Charge product range and the available sizes of our current products. We’re starting by launching each product in the size that will suit most customers. PhosLock is a very concentrated lanthanum chloride–based phosphate reducer, so most aquariums require only a small amount to lower phosphate levels. That’s why it is currently sold in an 8 oz bottle. Larger sizes are being worked on and will be added as the product range expands.
