Quantum AR Phosphate Remover 1L — Litre of Lanthanum Phosphate Remover for Large Reef Aquariums
Large systems with big fish populations produce phosphate faster than any media reactor comfortably handles, and liquid lanthanum is the usual answer. Quantum AR Phosphate Remover 1L (SKU: QA151000) is a solution of purified lanthanum in deionised water that binds ionic and chemically bound phosphate and precipitates it out, leaving the filter to collect the result. The litre suits reefs and fish-only systems of several hundred litres, and Quantum rates it for LPS, mixed, SPS, NPS and FOWLR aquariums, with the one exclusion of tanks that contain live plants.
The dose depends on the reading: per 100 L daily, 0.1 to 1.0 mL at 0.03 to 0.25 ppm phosphate, 0.5 to 2.5 mL at 0.25 to 1.0 ppm, 1.0 to 5.0 mL at 1.0 to 5.0 ppm, 5.0 to 10.0 mL at 5.0 to 10.0 ppm, and 10.0 mL above 10 ppm. On a 500 L system at 0.5 ppm that is a few millilitres a day, so a litre lasts well beyond the reduction phase. The solution is added directly into high water flow and suits dosing pumps. A fine white film on the glass indicates overdosing and the product is not for aquariums containing live plants.
Usage & Application
When to Use
- Large reefs and FOWLR systems: Displays of 400 L and more with a steady phosphate input from feeding.
- Predator and large-fish tanks: Heavy feeding that keeps phosphate high despite changes.
- Dosing-pump systems: A litre keeps a reservoir supplied for months at maintenance rates.
- Any marine system without live plants: LPS, mixed, SPS, NPS and FOWLR.
Dosing & Administration Guide
- Test, then select the row: Match the phosphate reading to the table and begin at its lower figure.
- Deliver into high flow: By hand into strong circulation, or through a dosing pump line.
- Look for film: A white haze on the glass means the daily amount should be cut.
- Follow the level down: Retest every few days and move to a lower row; not for planted tanks.
Product Specifications & Highlights
