Problem for years of no chlorine in my pool and I was googling and come across the BBB method and got me a new kit:
Taylor k-2006c Complete (FAS-DPD Chlorine) okay I started with the 10% bleach on 7-7-16 I tested my pool.
i read about slamming your pool to kill alge do I get my FC up to 20? How many days and what is it I need to do? All help will be appreciated, I have had a problem with a dark alge. Here are my test readings.

morning Night Next morning
7-7-16 7-7-16 7-8-16

CC- 0.0 0.6 0.4
FC- 0.0 added 512oz 10%. 7.4 1.2
Waited hour retested
PH- 7.8 7.8 7.8 Does chlorine lower PH?
TA- 140 120 110
CH- 190 170 170 Do I need to test for CH?

i lost a lot of chlorine over night. I am getting aggravated, please help me. What do I need to add or do today?

Thank you and God Bless

Welcome to TFP!!

To eliminate teh algae you need to read the directions on SLAMing your pool in the How To section of Pool School and follow that procedure completely to the end.

• CC is 0.5 or lower;
  
• You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less);
  
• The water is clear.

When all three are true, you are done SLAMing and can allow the FC to drift down to normal levels.

When reporting test results, pleas type them in this way:
FC
CC
pH
TA
CYA

Typing it in lines like you did is extremely hard to read.

No need to keep testing CYA. It doesn't change that fast, so use 50 for your SLAM.
