I've been doing very little to my pool this summer, but I've probably learned more about this year since our than our first season. Haven't been around it much due to some circumstances, but I'm amazed how much neglect it manages to handle with so few issues. I have had two cases of near Algae blooms and there have been several times I've caught it with Zero FC. It is a testament to what keeping a good pool consistently can do in terms of preventing problems. You really have to neglect one to see problems arise, or at least in mine. My CH is now North of 1000 and I've been out of range high on pH more times than I care to admit. With all this I found my Cya <30 today as well. No scale, no algae outbreaks, and not even a hint of waterline scale. Nothing else going on either that I can see, but it's a little more than amazing. I'd never suggest or condone neglecting a pool like this, but I've had little choice really. As far as I can see, it really pays off keeping up with it day to day, if nothing else just to give you some cushion. One thing I'm sure of is that serious issues don't arise overnight, or at least not in mine. I've adjusted everything today, and it shouldn't be an issue from here now, but I thought I would share this.
