Due to health issues my salt water pool has gotten pretty green, mostly on the steps, where the auto cleaner can't get to, but also starting on the bottom.
Where do I start?
Check all chemistries first? Salt level, CYA, Ph, Chlorine?
Or brush pool first and vacuum up as much loose algae as I can, then chemistries?
I do need to check water temp and see if my chlorinator is starting to work.
Thanks in advance!

Test results:
Water Temp 63F
Salt 3000ppm
Ph 8,2 Way too high
Cl 0.0 Just bad
CH 500
TA 120
CYA 30 Should be higher for my salt pool in Las Vegas summer heat?

I am unfamiliar with the FAS-DPD test.
Should i be brushing and vacuuming up the algae that I see as I do the chemical procedures? Close up it looks rather yellowish green.
 
Read the SLAM process link above. Follow it. Common issue.

The TFPRo has the FAS-DPD test. You use the R0010 powder and R0011 reagent. Follow the instructions.
 
TFP SLAM level level chart says 12ppm. Poolmath says 2 gallons of chlorine to achieve that level.
"
  • Use our PoolMath calculator to determine how much liquid chlorine you need to add to raise your FC from zero to SLAM level. Then, purchase DOUBLE that amount.
So do I add 4 gallons at the start? Or am I doubling the amount bought so I have the extra 2 gallons to add during subsequent days?

Should I wait till the morning to start the SLAM?
Or start now, 2pm, and check every 3 hours, till i head to bed?
 
Doubling the amount bought. Purchase twice the amount of chlorine to get from 0 to slam level. This is just a start.

Add whatever you need to get from current FC to slam level.

Start now.
 
I would get about 10 gallons of 10% liquid chlorine from Walmart, etc.
  • Check and adjust the pH to between 7.2 and 7.5. The pH test isn’t reliable during a SLAM so adjust pH before you start. There’s no need to test pH again until your SLAM process is completed. After SLAM, when your FC drops below 10, you can test and manage pH as normal.
  • Turn off all other forms of chlorine generation, like saltwater chlorine generators, puck chlorinators, etc.
Add the amount of liquid chlorine needed to get to 12 ppm FC. Run the pump 24/7. Brush a couple times per day.
Test the FC every 2-3 hours and raise the FC back to 12 ppm.
Once the FC holds close to 12 ppm after 2-3 hours, you can start checking FC 2-3 times per day.
