Adsorber granulate and Phosphate Fixer on an iron (III) hydroxide base for the irreversible removal of phosphates from aquaria and pools. Can be used in fresh or salt water.
Method of use
To avoid clouding of the water, rinse before use in a bucket of water until the rinse water is almost clear. This will remove the remaining particles of dust from the production of the granulate.
Please place the little bag somewhere in the water circulation where it has as much water flowing around it as possible. For this purpose, the canister filter is of course ideal, as the quickest results can be achieved here due to the high through-flow.
The granulate has been designed for the rapid lowering of phosphate concentrations > 0.5 - 1.0 mg/l, which will not be lowered quickly or lastingly enough by change of water alone (particularly with higher concentrations of phosphate, the phosphate quickly re-dissolves out of the sediment after a water change with phosphate-poor water).
Please do remember that aquatic plants need a minimum quantity of phosphate to thrive, and do not allow the values to become too low (0.25 mg/l is an acceptable remainder). In tanks for fish only you need of course pay no attention to the above.
Mode of action
Existing phosphate dissolved in the water is in the first stage bound adsorptively to the highly porous iron (III) hydroxide surface. In a subsequent reaction it is converted to stable iron phosphate according to the following chemical equation:
Within a few days, the phosphate content in the aquarium or pond is effectively lowered, according to the extent of the original phosphate concentration and total quantity.
- Very effective at low cost
- High loading rates due to highly porous surface
Compared to iron or aluminium salt solutions
- No change to the pH in the treated water
- No entry of anions to increase conductance
- Not a hazardous substance - no problems with storage and handling
A minimum of 15 g of phosphate / kg iron (III) hydroxide granulate according to the manufacturer's information
According to own measurements under the conditions of use, more than 20 g phosphate / kg of granulate are bound within 30 days.
As a positive side effect, silicate (silicic acid) is always bound in greater or lesser quantities alongside the phosphate.
After the depletion of the material you can either put the complete fleece bag into the non-recyclable waste, or open it with scissors and add the phosphate-loaded iron hydroxide granulate to your compost or compost recycling waste.
Ready for use, bonded into a tear-proof and non-decomposing polypropylene fleece bag.
