Neutralizer Blend

Neutralizer media is typically a blend of calcium carbonate (calcite) and magnesium oxide (Corosex

). This media is used to elevate the pH of acid water

and is generally used when the pH is approximately 6.0-6.5. The ﬁ lter media dissolves when water with a low pH passes through. The blend is used to

take advantage of the fast, vigorous pH adjusting capabilities of Corosex and the slow, long-lasting capabilities of the calcite. Neutralizer is typically not

recommended when the pH of the raw water is below 6.0, because the dissolve rate would be high and thus constant maintenance of the CBF Series

Residential Backwash Filtration System would be necessary. In these cases contact our Customer Service Department at 1-866-990-9785 for recom-

mendations.

Neutralizer media may require replenishment periodically. The frequency is dependent on the raw water pH and your water consumption habits. The

lower the pH and the higher the water usage, the more frequently replenishment will be required. One easy way of determining when to replenish is by

placing a mark on the outside of the tank at the level of the media when ﬁ rst installed. Periodically shine a bright light through the tank and compare the

current level to the mark, if it is down more than three (3) inches, add media to the mark. If you are unable to see through the tank, remove the control

valve and measure down to the top of the media. The tank should be 2/3 full. If not, add media.

IMPORTANT NOTE

Since the neutralizer media dissolves as it elevates pH level, it will increase the hardness of your water. If your dwelling is equipped with a tankless

water heater, the installation of a water softener may be necessary to help prevent the heater coil from plugging.

Filter Sand

Filter Sand is recommended for high sediment loads. Make sure to visit our website at www.aquapure.com for a free water analysis kit to help assist

you with product recommendation or contact our Customer Service Department at 1-866-990-9785 for recommendations.

Calcite

Calcite can be used when only a slight pH adjustment is required. Calcite is sacriﬁ cial (dissolve) when adjusting pH and will thus increase hardness as

well. Replenishment will be required periodically, once again depending on raw water pH and water consumption.

Corosex

Corosex is a specially processed hard, bead-like magnesia, adapted for use in ﬁ lters to neutralize acidity by increasing the pH value. By neutralizing the

free carbon dioxide in water, Corosex can correct red water conditions and render it less corrosive. Corosex, being a reactive magnesium oxide, is used

most effectively where pH correction is substantial or high ﬂ ow conditions are in use. Being soluable to acidity, Corosex will slowly dissolve and will

have to be replenished periodically. On a per weight basis, magnesium oxide can neutralize ﬁ ve times more acidity than can calcium carbonate. This

results in greatly reduced chemical usage for the same pH correction. Under certain ﬂ ow conditions, Corosex may overcorrect and create a basic (high

pH) condition. Corosex can be effectively combined with Calcite to combine the high ﬂ ow neutralization properties of Corosex, along with the slower

reacting low ﬂ ow properties of Calcite reducing potentially high basic properties due to overcorrection. As Corosex’s magnesium oxide neutralizes the

water, it will increase hardness and a softener may become necessary after the neutralizing ﬁ lter. Advantages of Corosex is the high degree of activity

and speed of correction allowing high ﬂ ow rates, as well as the high capacity, which means less chemical usage.

IMPORTANT NOTE

Since both calcite and Corosex increase hardness of your water, if your dwelling contains a tankless water heater, a water softener must be installed

after the ﬁ lter to help prevent the heater coil from plugging with hardness material.
