What is Acidic Water?
For private home systems and wells, acidic water is one of the most common culprits behind pipe corrosion. The pH of a liquid reflects its concentration of hydrogen ions; the lower the pH, the higher the concentration and the more acidic. Acidic water has a pH of less than 7. The properties of acidic water make it much more corrosive to metals used in plumbing systems than alkaline water, especially copper.


You can test your water's pH using pH Test Strips.
Causes & Negative Effects
Commen causes of acidic water include acid rainfall due to airborne pollutants, the compostion of soil and bedrock through which the groundwater moves, coal mine drainage, chemical dumping, plant decomposation, local flooding and other natural disasters. Acidic water can be identified by blue staining (from copper pipes) or red rust staining (from iron pipes) left on pipes, fixtures, and in sinks.

The more corrosive nature of acidic water can cause toxic metals such as lead, copper, zinc, iron, and manganese to leach into your water from your pipes, leading to a number of health concerns. It can also cause your pipes to deteriorate at a much faster rate, leading to pinhole leaks and over time, total pipe failure. This can burden you and your family with huge expenses to replace the infrastructure. Acidic water can also leave water tasting sour or metallic.

Acid Neutralizing Solutions
Calcite is a high grade of naturally occuring calcium carbonate. This media is an inexpensive option for bringing acidic water to a neutral, less corrosive pH. One of the greatest advantages of calcite compared to other acid neutralizing medias is its self-limiting property. Calcite, when applied correctly, will only correct the pH enough to reach a non-corrosive equilibrium, and will not over-correct and make the water too alkaline. Calcite neutralizer tanks are able to easily neutralize acidic water from 5.8 - 6.6 pH. Below this, a blend of calcite and FloMag Corosex media is recommended for best results.

FloMag Corosex is a naturally occuring mineral made of magnesium oxide. Because it is highly reacitve, this media is used most effectively with a starting pH of 4.5 - 6.0, or where high flow conditions are in use. However, because it can neutralize five times as much acidity as calcite on a per weight basis, under low flow conditions Corosex may overcorrect and create a highly basic condition (water over 8.5 pH). Therefore, it is strongly recommended that Corosex is only used when blended with Calcite, and are best combined at a Calcite/Corosex ratio of 80%/20% or 90%/10%.

The All-In-One Acid Neutralizing Filter System includes everything you need to need to correct pH levels enough to reach a non-corrosive equillibrium. Vortech technology allows the system to operate without the addition of gravel. This system features the Clack 1191 In/Out Valve for superior upflow filtration, a corrosion-resistant fiberglass reinforced tank, and has options for whatever Calcite and FloMag Corosex ratio you need for your specific application. This type of filter tank is almost always followed by a water softener used to remove the "hardness" added by the filter tank ( as the media dissolves it increases the hardness in the water ), and the softener can help remove iron that is often in the water.
