OK, I understand. Good news - the algae is not visible this morning. I haven't run a test yet, but all I see is some residue at the bottom of the pool. The Polaris hasn't run yet.

When the pool was first filled, and we got the "pool school" lesson, I did wonder about the weakness of the system that included an element that only increased and could not be removed except by pool drainage. That seemed a little ridiculous to me. But we've had very minor problems with the system as is - the ph got out of whack a couple of times with rain, or we'd run out of chlorine in the feeder but catch it before anything happened.

Even this time, I could have caught it earlier had I noticed what dh was saying...He's been saying something about stains for a week now but I just blew it off. And dear son hasn't been testing like he should, even though we have a nice 6-way kit. I will order Ben's kit when it's available again!

So what DO you do if you go out of town, and you aren't there to add bleach?
