Hello all. I'm on my second pool, The first one was a tiny <2000 gal pool and I swore by the BBB method. Now I'm on one that is a tad bigger, around 8900 gallons, and this time I said I wanted a better filter media. So I did a bit of research (not much) and thought that getting zeolite sand would be a good idea. What appealed to me was the 2-5 micron filtering size compared to the 30-40 micron of the sand. But my filter is one speed and I just learned that Zeolite doesn't like fast flow. I went about 3 months without any issues. We went on vacation and got back to a green pool. I thought that would be no issue since I could correct the green pool in about 3 days. Well, it's been 3 weeks. The pool is teal, I've been shocking it almost every day and the bottom still has a bunch of algae, and super cloudy. After some research, I think the culprit is the Zeolite. So tomorrow I'll be getting some plain 'ol pool sand and not the Quickrete kind. Crossing my fingers that solves the issue.
