SLAM Help Needed

[tiny_torpedo]

Hi all, trying to get my pool ready and it is a green mess - algae growing everywhere. I want to start the SLAM process and had a few questions. Here are my test results before I've done anything:

FC=0
CC=0
pH=8.2+
TA=50
CH=225
CYA=0
Salt=2000ppm

Should I raise my CYA to a certain level before I start the SLAM? Also, should I lower my pH before I start? Thanks for any advice you can give.

How are you testing your pool water chemistry? Please put what test kit you have in your signature.

Did you have CYA in the pool prior to winter? Have you fully circulated the water prior to your testing?
If so, I suggest you first test for ammonia.
To check and defeat ammonia, if necessary, is to raise your FC in the water using enough liquid chlorine to get to 10 ppm using PoolMath. Circulate the pool for 15 minutes. Test FC. If at 5 or below, add LC to get to 10 using LC, circulate for 15 minutes, repeat until your FC is above 5 ppm after the 15 minute circulation.

Let us know your results after you complete that.

Thank you, sir. I am using the TF 100 Test Kit w/SpeedStir (will update my signature with that info). I did have CYA prior to winter, but I did not conduct any tests all winter. Water has been circulating 10 hours a day non-stop through the winter, so yes the water had fully circulated prior to testing this afternoon.

I will test for ammonia now using your instructions and report back. Thanks!

OK, I did the ammonia test and added 1.9 jugs of 128 oz liquid chlorine (10%). After 15 minutes of circulation:

FC =10
CC = 0.5
Everything else tested the same as above

Great.
Follow the SLAM Process process. Read the article. Get 30 ppm CYA in the water and work your pH down to 7.2. Your TA is on the low side so be careful adding acid. Follow PoolMath
