So we knew we had acidic water, but we did a test yesterday & it's a 4. That's really bad! Plus there are some nitrates. We just did a home kit test & I'd like to get the nitrate level professionally tested before investing money in case it's not at an unsafe level. ANYWAY...we're looking into water neutralizers & possibly reverse osmosis units for drinking water. Anyone installed anything like this? We have well water. There are so many systems that it's: We are on a VERY tight budget. Thanks!!
