Review on Membrane Solutions Refrigerator Replacement Cartridge 10 Pack by David Everett

My tap water comes out at 230ppm and the reverse osmosis water shows 0ppm on my Blue Lab meter. I bought this carbon filter set and connected it in series to water the plants. Starting with a 50 gallon RO tank with 0ppm water, I disconnected the RO from the ball valve and replaced it with this water supply. I continued to water the plants and watched the ppm growth as this water started to integrate into the tank. Now it reaches 210 ppm, which is almost the same as in unfiltered tap water. I ordered a sediment filter to add to two carbon filters but I doubt it will help remove dissolved solids. Just take a look. Anyway, I hope it filters something out. I might end up getting a charcoal filter and see if that makes a difference to the set of filters I set up.
