Day 14 (7/18/09)
8:00 am - FC=17, Added ~131oz of bleach
10:30 am - FC=17, Added ~131oz of bleach Loss=1.2 ppm/hr
11:00 am - Vacuumed cover best I could and backwashed pool to lower water level which was too high. Added 4 oz DE and noticed no change after about a minute. Kept adding DE to the point of 24 oz. Level after a few minutes as about 3 PSI above none.
12:00 pm - Read article on adding DE to sand filter and realized I messed up. Checked PSI which was now 10 over. Oops

Backwashed again. Water level still good. FC=19.5-20, suprised by this reading

so no change. Will check again at 2pm.
1:30 pm - Added 2oz DE
2:00 pm - PSI went up about 1/2 PSI. Added 2 more ounces and PSI quickly went to 2 over so I guess that 3 oz is where I should be next time. FC is still hasn't changed. Could this be the beginning of the end for the algae. I would expect a little loss with the heat/sun even with the cover on, but I'm not complaining.
4:00 pm - FC=17, Added ~131oz of bleach, Loss=1.5ppm/hr
9:45 pm - FC=16, Added 182 oz of bleach, Loss=.7ppm/hr
