We haven't actually been in our pool since before we left for 4 days, due to the algae we've been fighting. (The algae is now presumed to be dead due to being shocked, but we are trying to get the water filtered so it won't be so cloudy so we can see the bottom in the middle before we get back in.) (Which is why I'm possibly looking into upgrading my filter pump as well.) I just ordered the Taylor K-2006 kit Monday evening and am awaiting it's arrival so I can do more detailed testing on our water. Right now we are relying on the Walmart OTO drops test for chlorine, and having a hard time distinguishing between the various shades of yellow, so our chlorine level is currently just a guesstimate.

Thanks for the link, that was very helpful. Although these bugs probably won't be a problem, just the thought of millions of tiny bugs being there is gross. We already have found a few of what we think are water boatmen in our water (hoping they aren't biting backswimmers).
