If you are on a water supply that is below 5 pH, the calcite will not function to its intended purpose. In this situation you would require a pH boosting media to raise the pH above 5.
Please contact us prior to purchase to ensure that this product is right for you.

pH Boosting Filter Media
This media vessel will require a 1 way valve (check valve) installed behind it to avoid negative pressure in the system caused by a sudden back flow of water, It is also recommended that you include an isolation valve for easy maintainance when re-filling the vessel.
Whole House Calcite Filter
We have put this together this due to popular demand.
Now days many people are getting brand new Poly Rain water tanks installed on their property. Rain water is commonly known to be in a very acidic state (around 5pH) naturally, and it is only when it comes into contact with earth or other organic material that the pH rises to neutral and even alkaline levels. However when you have clean gutters and a new clean poly tank, there is no organic or inorganic matter to dissolve into the water to raise the pH, thus you are left with highly acidic water sitting in your tank. This can cause extensive health issues in the long term but it may also affect your plumbing work throughout your house. Copper is known to be the worst affected part of your house by acidic water, you will notice a blue/green tinge to the water which is a signal that copper is dissolving into your water. Acidic water works its way from the inside out and if left long enough untreated, may cause your entire copper pipework to fail and need replacing.
This brings us to the solution to acidic water, The Calcite Filter.
There are many note-worthy features that need to be addressed with this system.
The system is fitted with a Manual Multi Port Valve for easy and efficient backwashing of the system, again, saving you time and effort to maintain the system. This will also mean you do not need a second expensive post filter to catch the fine particles/dust produced by the calcite when it is first used.
The filter is made up of 2 main filter components:
Firstly: A bag of filter gravel which acts as a sand filter, filtering out dirt sediment and other particulate in the water.
Secondly: We use a High Grade Calcite Marble filter media. This calcite is the Highest Quality available in Australia. This in turn will provide much better consistency and filtering life.
The way this filter works is by dissolving traces of calcium into the water to help buffer the pH back to neutral. On average you will need to refill about 1/2 to 1 bag full of Calcite Marble per year (which depends on water usage + pH of incoming water). This is done through the convenient side fill port mentioned above.
The drop tube is pre-cut to length and fits snugly in the centre hole of the vessel (there is a port in the bottom of the vessel that the drop tube will sit in snugly). There will be no need to cut the drop tube.
We recommend that you buy a few spare bags of calcite with your order so you have it on hand for when you need to top up the calcite filter.

Other than pH testing, what warning signs do I look for if I suspect that my rain water tank is acidic?
Acidic water can have a few different warning signs. The main offender is any green or bluish staining around fixtures or discoloration in the water itself. This green residue is the copper that was once present in your plumbing (or fixture) that has been dissolved into your water due to a low pH. In some cases, some people have actually had their hair turn green due to the high levels of copper in the water. At the high end of this, people have become sick due to the levels of copper that they are drinking in their water. A pH test is highly important, especially if you have copper plumbing or fixtures.
How do I test my rain water pH?
pH test strips are the best way of determining an accurate pH. When testing this, you must ensure that your pH test strips are high range i.e. they go from at least 4-10 pH. People will commonly go to a pool shop or use pool test equipment which is handy, however the pH range is usually 6.2 and up.
It is vital that you have an accurate pH reading to determine whether or not Calcite alone is enough to treat the water. If your pH is lower than 6.2 it is highly important you treat the water to avoid damage to your plumbing and also your health.
What is the maintenance with a Calcite Filter?
The calcite filter will slowly over time introduce trace amounts of calcium into your water (5-20ppm) which is enough to elevate your pH from acidic to a neutral state.
In doing this, the filter media itself literally dissolves so will need to be topped up eventually.
To determine when you need to top up the filter, simply test your pH, if you get a reading of 7pH or more, the filter is working fine. However, if the pH drops under 6.8 pH, you will require a top up of calcite into the filter. Usually an average house will go through anywhere between half, to 1 ½ bags of calcite per 12 months, obviously this can vary due to water usage and pH. When you top up the calcite filter, you will need to give it a quick backwash to remove any calcite dust. Flush the filter until the water runs clear then the filter is ready for use.
Do I require any other filtration in conjunction with a calcite filter?
As the calcite filter already includes a manual backwash head, you will not require a sediment filter after it as you can wash the filter until the water runs clear. However, if you are on tank water, we strongly advise that you have standard filtration accompanied with Ultraviolet Sanitation. All tank water should be filtered.
Is everything supplied with the system, or do I need to purchase anything extra?
The Calcite Filter is supplied with filter gravel, and Calcite marble for the filtration. Usually a plumber will conduct the installation, in which case the plumber should supply any additional fittings or pipe needed for your specific installation.
There is 1 Key item you will need to ensure is purchased/installed.
1. One-way Check Valve (Non Return Valve): This is to ensure that no back flow occurs in the event that the water somehow vacuums backwards through the vessel. If this occurs, there may be enough negative pressure to cave in the filter vessel.
Will a Calcite Filter work on pH lower than 6?
Calcite filter media has an effective pH range between 5.2 and 6.8 pH. This pH range is the most common that you will find in domestic tank water.
However if you have very clean tanks and gutters, you may have a pH that is below 5.2 in which case Calcite on its own will not work. The solution to this is to use a Magnesium Oxide media which dissolves in all acidic pH ranges, giving the pH a “Jump Start” so that the calcite can take over. This is the same media we use in our “High Alkaline” Water filters.
