According to a water test Svc. My silica is testing 1 mg
/l. Copper is testing .09 mg
/l. Doing a 15 percent water change every 14 days. Tank is about 4 years old and these tests are consistent. I am using a rodi
unit and an auto top off. Changed all filters in unit a couple months ago. Running brs Gfo
in a reactor. Changing 2 cups every thirty days. Any other suggestions to reduce silica and copper. My water is cruddy going into my rodi
unit. 430 tds
going in and around 2 coming out. When I changed all filters it dropped to 0 but was back up to two within 50 gall of filtering. Can't afford to change them weekly!!!
