Water flows upward through the media, ensuring even contact and reducing the risk of channeling, which leads to consistent pH adjustment. The unique 'lifting' motion of the water flow helps to circulate the media and help prevent clumping of the calcite as it dissolves. They require less maintenance, as there’s no need for backwashing, which also saves water. This design makes them ideal for those seeking a low-maintenance, cost-effective solution for neutralizing acidic water.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #e03e2d;\"\u003e\u003cem\u003e\u003cstrong\u003eBackwashable Calcite Filters\u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e, on the other hand, use a downward water flow and require periodic backwashing to clean the media bed.

However when you have clean gutters and a new clean poly tank (or a poly-lined steel 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 easily corroded by acidic water - if this is happening in your home, you will notice a blue\/green tinge 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" height=\"229\" src=\"https:\/\/www.filtersystemsaustralia.com.au\/media\/wysiwyg\/Cooper_Leaching_1.jpg\" style=\"display: block; margin-left: auto; margin-right: auto;\" width=\"1068\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: 12px;\"\u003e\u003cstrong\u003eHave you checked for signs of copper pipe corrosion in your home?

Ideally you should locate where the cold water enters the building or tees off to the hot water system. Either way, you will need access to modify the pipe work for system installation.

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 ph. 7-8 or higher depending on the pH of the incoming water. Note: when using magnesium as a pH booster, the pH will likely be above 8 when the media is new and will gradually lower over time. We recommend that you buy a spare bag of Magnesium pH Booster with your order so you have it on hand for when you need to top up the filter.\u003c\/p\u003e\n\u003cp\u003ePlease note that magnesium can leave a slight residual metallic taste in the water.
