Review on 🔹 APEC PHPLUSKIT 14 Alkaline Calcium Carbonate Supplement by Fernando Beck

Package arrived quickly and without damage. As for the product itself, it won't work for you if your pH is 6.5 or lower. This filter makes you neutral from this point, but not basic. Calcium carbonate is intended for already neutral water. Also if you filter twice with a razor or something to lower the TDS you will lose the pH.
