Long story short: we had new pebble-tec installed a year ago. Since the fall, we've had a guy taking care of the pool. We've had some algae over the winter (not bad, but some on the tile/grout mostly). Today, I noticed a pretty major calcium line. It turns out auto-fill was off, too. Is this just kinda something that happens? Did the auto fill being off contribute?
Is this just something that happens? Anything we can do to avoid it in the future?
