I need help! I have turned my water Brown/Green, I did my calculations and my CYA level was high and Chlorine level was way low. I had poured 2 bottles of bleach in to start the slam process to get the cloudiness away, well it turned green!

I have drained the pool down below the skimmer and in the process filling it back up.

How do I get this fixed ASAP! Family is coming into town Saturday...
 
You likely didn't do anything wrong. It sounds more like iron in the water. Have you had issues with iron before? Where does your fill water come from? How are you currently testing your water?

Please provide a full set of test results.

I'm not exactly an expert in the subject, but I can at least get the conversation started. Take a look at these articles.


 
No I have not had any Iron issues.. This is our second year with this pool. First year close and open from the start. Since we live in country we use well water with Softener as we hook it up to the house.

when I first started:

CYA was 60
PH was 7.4
Salt is at 3300
Chlorine Drop test was 5

We use the taylor k-2006c
 
You haven't saved any of your test results when using Pool Math, so they don't appear under your username.
CYA isn't high with a SWCG, it is almost perfect.
Your FC, if you mean you added 10 drops, so the result is 5 ppm, is a tad lowish, but not out of range.
What bleach did you add? Show a photo of the jug.
Also show a current photo of the pool.
 
Where are you in the Midwest? We can get you better chlorine if we know where you are.

Check out @JessBlount617 saga from last year, might help.

The Dollar store bleach is likely only 5-6% concentration. A gallon will only raise your FC 4-5 ppm. I could not find information on ingredients, so can only hope it didn't contain additives for color protection, splashless, etc. Does the back give any information about the contents?

Get to WalMart or Home Depot and buy their pool chlorine. Twice as strong (10-12% depending on the specific kind), for only slightly more. You'll end up saving money.
Your jugs didn't have near enough to get you to SLAM level. Likely that the brownish color is what algae it did manage to kill off. The greenish would be still living algae.

Read the SLAM article: SLAM - Shock Level and Maintain

You'll need a few cases of liquid, and have to monitor levels very frequently. You want to get your CL up to 24, and keep it there. It will be safe to swim at that level, as long as one can see the bottom.
