Acid neutralizer iron filter units where one tank is used are often a marginal approach. The only time that it is a good idea is if you are CERTAIN that you have only red water iron. And no clear water iron. In addition, you may not have enough space to add an iron filter after the acid neutralizer for some reason. The proper approach if you have both iron issues and pH issues, is an act neutralizer followed by an iron filter. You really should not mix the minerals for both into one tank. This is a marginal approach often used by marginal water treatment dealers to create a lifetime of expensive service calls. Have one tank to raise the pH. And then have another tank to remove iron, sulfur, manganese etc. Or use a dual tank system like the one below to save water and be the most efficient when cleaning itself. The unit is fully automatic.
Dual Purpose Tanks
We do sell a twin tank system where one tank is the acid neutralizer and the other is an iron filter. The first tank raises the pH. That allows the second tank to remove iron, sulfur, manganese, rust, dirt, sediment and chemicals. The best iron filter for the second tank is our Popular Terminox™ Iron, sulfur and manganese filter. It requires not salt or chemicals or maintenance. So all you ever have to do with this premium filter is add a little mineral to the Acid Neutralizer tank every year or so. How often depends on how low the pH is, how big the tank is and how much water you use. The average for most customers when the tank is properly sized is about once per year. The cost for the replacement minerals usually cost $25 to $35. These units are very efficient and fairly inexpensive. Each one is made to fit the exact well that you are on. Just give a friendly water tech a call to determine which one is right for you. Or read one follow the instructions under items number 7, 16 and 17 on this page: Sizing the Correct Filter
Backwashing Acid Neutralizers
Acid neutralizers normally do not need to be backwashed as often as iron filters. They serve two entirely different purposes. If you should use an acid neutralizer to remove iron, you must backwash it far more often that you would otherwise. As it backwashes it uses even more mineral. So in this regard you are using way more pH increasing minerals than necessary. Of course for the company selling these minerals to you it is additional ongoing income.
A Flow Rate Check is Essential
You should also be sure to do a flow rate check as described on our Articles and FAQ's page under item #7. That is how you know what size you need. It is also helpful to know how many permanent residents are in the home. There are different solutions for different pH values. In some cases you may need two backwashing tanks if the pH is really low. You should contact one of our expert techs once you know what your pH is so they can tell you exactly what you need. Be VERY wary of people who add acid neutralizer minerals in other tanks, such as water softeners and iron filters.
Don't Mix Minerals in One Tank
It makes no sense at all in a proper application and raises many different concerns such as minerals shifting in the tank, unstable mineral beds, pH ranges that fluctuate greatly, and often it unnecessarily raises hardness levels in water that is not hard, which then may require the addition of a water softener and drinking water system. DO NOT let companies sell you units with pH increasing minerals such a calcite in the SAME TANK as other filtering or softening minerals.
