Don't fret, Dave. I started this year with the same look. Considered investing in a license to sell frog legs from mine, then decided to clear it up and swim instead. Really nasty at the start, (tadpoles, larvae, and anything else you wouldn't want to swim with, but after about eight days, had it back to clear and from there it was a quick leap to sparkling. Point is, I used all the advice I have read on this forum, followed the steps they have provided, and the experts here can get you there too. The information they provide has proved invaluable to me, as I'm sure you will see. Just follow the steps they provide and keep posting pics and test results. Soon you will be floating in a clear pool and it will all be a bad memory. Good Luck.
