I had standard sand. It was at least 10 years old. I had it changed just due to the age, but the pool had no issues. The pool company recommended zeolite. After changing to this I was not able to get the water 100% clear, it was cloudy, maybe about 85% at best. Also, seemed like a reaction was happening when I shocked and the water would turn colors as if I had metal. My old sand looked new when it was removed, I decided to go back to standard silica sand. My water is now 100% clear. When I removed the zeolite it was very green. I had my water tested many times and did myself both before and after. Balance was not an issue in either case. Maybe it’s a coincidence, but I am not using zeolite again, seemed to not work for my pool. Perhaps it has to do with where I am, we do have a lot of trees etc around.
You can see the image where I dumped my old sand and the zeolite. Maybe it’s supposed to look like this…
