Overwhelmed with pool chemistry

[muundance]

Here are the results of the water test. Not good.

FC - 0
CC - 2.6
PH - 7.4
TA - 135
Ca - 135
CYA - 20
Cu - 0
Fe - 0

They didn't test for silver, however manganese is a no.

I appreciate your help with this.

Get three gallons of bleach in there to get your chlorine up to 15, and keep it there. Check it several times a day, as algae will use it up. Add bleach as required. You can check with a standard kit by diluting the water sample with three parts distilled water and multiplying the result by four.

Looks like you have an algae problem. With a CYA of 20, you will need at least a FC of 12 ppm to kill the algae but better to start at 24 ppm since it will be used up fairly quickly killing algae and converting your high combined chlorine. For 12% chlorine, 24 ppm is 2 gallons of chlorine per 10000 gallons of pool water. For 6% you will need twice as much. Keep the CL level to at least 12 ppm until the algae is gone and the pool is clear. Once you kill the algae, the pool may turn cloudy. This is good. Keep a watch on the chlorine so it does not drop during this period. Also, keep the pump going 24/7 and vacuum the dead algae up when you see it on the bottom. Good luck.

Thank you for you help. Any idea where I can find the 12% chlorine?
