Sunday ~8:45 a.m., May 29, 2011 (Day 4)

Our pool looks about the same as last evening – bluish in color with lots of settled debris, and some signs of seeing the bottom in the deep end. However, the water sample does have a smell of chlorine.

Water temp = 70 deg.
FC = 8.4
CC = 1.4 (5 x 1.4 = 7.0 good!)
pH = 7.5
TA = 50

I’m not quite sure as to why the CC level has risen – other then an error in the testing process?

My best guess is that I need to add 4.3 gal. of chlorine (bleach 6%) this a.m. (in order to keep the FC level elevated throughout today), then test / adjust the chlorine levels later this evening in order to determine if the FC level remains stable overnight (or maintains a 5:1 ratio with CC).

Many “thanks” for all of the helpful recommendations I have received from the PoolForum, especially the latest from both Ben & Watermom,

PS – I will backflush this a.m. in hopes of reducing the pump pressure.
