they get clogged before the six month limit.
They're new. They are doing what they are meant to do. I am glad the rocks last for two years. I replace the old rocks with these.

Gravity Water System Mineral Stones
I was given. Berkey water filter system and my gifte also included theses stones. I am at the point where I have to replace the stones. They are a bit pricey, but I believe are necessary to return vital minerals into the filtered city water, so I purchased them. The used stones are going into my potted plants as ground cover... so no waste.
