Question about using titration method for testing cl levels

[aylad]

For a CYA of 60, then 20 ppm should be high enough for a shock. Raise the chlorine slowly, watching for any visible sign of staining.

Please disregard the test message. I had previously posted a message that somehow was lost in the submittal process.

To make a long story short I have shocked my pool twice over the past week. Once with a 20 ppm dose (8 gallons of 6% hypo) and yesterday I added an additional 13 gallons of 6% hypo.

I tested my water today and here are the results:

FC=.2
CC=.2
pH=7.6
TA= 90
CYA=60

Please let me know what I should do next to get my cl levels up. I am adding bleach to pool by pouring it directly into the skimmer. My return inlets go through a cascading fountain (is the bleach evaporating).

Is it safe for me to swim with cl levels so low knowing that I have added over 20 gallons of bleach over the past week?

I would not swim with chlorine levels that low. With a CYA of 65 (which by the way is high enough--I would take the tabs out of the chlorinator and switch to plain bleach if this were my pool--the pucks are going to continue to raise your CYA, which in turn raises your chlorine level to maintain), you shouldn't have chlorine levels of less than 5 ppm...ever. If you are losing chlorine that quickly, then there's something consuming the chlorine in the water. In order to kill it off, you're going to need to get up to that 20 ppm dose and hold it there by testing and adding more chlorine as needed until the levels start to hold.
