Please contact us prior to ordering pH Booster Filter Media. This will ensure that you are receiving the correct product for your intended purpose.

If you are considering a Calcite Vessel as part of your tank filtration set up AND the pH of your tank water is below pH. 5, you may need to add pH Booster Filter Media (Magnesium) to get the correct final pH. Adding pH Booster Filter Media to water with a pH below 5 alters the water chemistry to enable the uptake of Calcite (Calcium). For this intended use you will see the pH range anywhere from neutral (7-7.2pH) up to high alkaline (8-9.5) depending on the pH of the incoming water.

We would recommend using a carbon post-filter either for drinking or on a whole-house basis, as magnesium can leave a slight residual metallic taste in the water. This taste is easily removed by carbon which will produce clean, sweet-tasting water.

Using Magnesium & Calcite Together

Calcite and Magnesium are two common types of filter media used for pH adjustments in Rain or Bore Water. These types of media will slowly dissolve into the water over time which will mean that they require replenishment to maintain high flow rate capacity.

  • When first using a pH filter media, follow the same backwash and rinse cycles as mentioned in the system instruction manual.
  • In cases where Magnesium and Calcite are used together, add the calcite to the vessel first, then add the Magnesium on top. Ensure that you do not overfill the vessel.
    • If the pH is around 5, fill the vessel with a ratio of 75kg (3x 25kg boxes) of Calcite to 7.5kg (approx. 1/3 bag) of Magnesium.
    • If the pH is around 4.5, fill the vessel with a ratio of 71.25kg Calcite to 10-12kg (approx. 1/2 bag) of Magnesium.
  • Test your pH ongoing and add more filter media when the pH drops below the minimum desired level (6.8 pH).

Optional Add On - Media Funnel:

The specially-designed Media Funnel helps you fill the vessel without spilling expensive media, or getting the media stuck inside the drop tube! Use this funnel to save yourself from the hassle of having to try and push the drop tube back down into the dense media (because you've accidentally dropped media inside the tube, and had to pull the tube out to empty it)!
