PO4 SiO2 Alsorb

Rapidly remove phosphate and silicate from marine aquariums.

It is highly porous with a large surface area, shaped for optimum water flow, and will not release phosphate or silicate back into the water. For best results place in a high flow area of the aquarium, for example in a sump, media reactor or canister filter.  If not contained in a reactor place in a media bag that will fully contain the beads.

Usage instructions

To obtain a target PO4 of 0.02mg/L (ppm): Use 40ml/100 litres of water in marine aquariums, or double that amount for fresh water.

ReefX® Alsorb will rapidly remove phosphate so it is important not to overdose.  Leave it in place for 4 days before testing levels.  If they have not reduced to near 0.02 mg/L then the Alsorb has removed the maximum amount from the aquarium and should be changed, otherwise leave it in place until the levels start to rise and then change.  You can increase or reduce the target level by changing the volume of Alsorb added but do so with care.  Avoid reducing levels by more than 0.5mg/L per day. This product generates heat when added to water and should be rinsed before use.  Place the desired quantity of Alsorb in a container with twice the volume of fresh water and leave for 5 minutes for the heat to fade.  Then pour out through a sieve, or drain and rinse again before it is ready for use.
