Opening pool

A 0 FC loss overnight is a sign the algae is well controlled. So, as the SLAM Process, states, the first sign of a successful SLAM is crystal clear water. So once you have that, then do a OCLT and check your CC.
A CYA test would be wise. Also, doing a SLAM with only test / add twice per day can make for a very long SLAM.

Thanks for the info. Unfortunately 2 a day during the week is all I can do. To make things worse I'm going to be out of town Saturday until late sunday. So per advice from a previous post, I'm going to float some pucks until I return.

Just so happen to be able to be at the house this afternoon long enough to test, Log: 6:30 - 11:30 - 13.5fc - 3 ppm loss. Added 2 cup 1 oz of Chlorine.

You should have done a CYA test because you're losing too much day time a sign of too much uv in the mix. The fact your OCLT is good doesn't help knowing that throughout the day your not accomplishing much on the slam side of things.

Just tested: cya is 40ppm.

11:30pm-4:25- 13fc drop of 3ppm. Dosed back up to 16ppm brushed pull changed out filter instead of just cleaning this time. Since it has been cleaned several times. It was in need of a new one.
 
Log: 6:30am - FC was at 13.5 - 2.4 ppm loss. Not sure if part of that was due to the Last test and add times was 4:30 pm, which still have about 3 hours of sunlight left, possibly the brushing as well?

You definitely don't want to start the OCLT until the sun has dropped, and do the second test in the am before light touches the water. Any bit of UV can influence your results.

Correct, I figured as much. The other 2 OCLT tests wered done at sundown and early morning no sun. They both had 0 drop. I've been doing SLAM for 5 days, now. Attached is a picture of now. Before this it was very dark green. Drained, then refilled and it was still a nasty green.

Question: Before I came here to TFP, I dumped about 3-4 bags of HTH Super Shock. Cal-Chloride. Water basically turned into a white cloud. Im no longer doing that. Just been using 10% liquid Bleach. The last I tested was that the CH was 130ppm. Ph was 7.2 the last test. Could there be Calcium Precipitation happening? Havent tested Ph since starting the SLAM process. Cause I know that PH readings can be inaccurate during the process. High Ph could effect the CSI correct?

I don't think the cal-hypo or has anything to do with your current water condition. I suspect that if you are doing well to maintain the proper FC SLAM level based on your current CYA, the process is a bit slow because of the limited filtration. I had a similar Intex pool at one time and those tiny cartridge' filters were not efficient at all. But it can still be done. Hopefully you have nothing in the pool (i..e ladder removed) that could hold algae. So be sure to review the FC/CYA Levels to ensure you are still at the proper FC level and brush the surfaces each day. Clean the filter each day if there is no pressure gauge, or if there is, when the pressure increases by about 25%. The chlorine will do the job.
 
Well back from out of town. Could see bottom of the pool sonewhat. Been gone since Friday evening. Friday evening was the last day I added to bring to 16fc slam level. Per advice above I floated 3 TRIchlor 3" pucks. Test showed 6fc level. Added 2 quarts 3 cups of bleach to bring to 18fc. Should I test cya again since floating pucks? They were barely dissolved. I wouldn't think it would have raised cya much over that short period.
 
Today is the clearest the pool has been. Can basically see the entire bottom of the pool. A little cloudy still though, but certainly the clearest its been.

Log: this morning 6:30am - 14FC, Will test around 5-5:30 - Added enough to bring to 18. I need to test cya to see if the chlorine pucks raised the cya from 40 to anything higher. They were only in there 1 1/2 days. Also added a skimmer basket sock which may have helped clear it more,

Brushed pool, vacuumed and cleaned skimmer basket sock. Was caked brown. Fc was 13 brought to 18fc, CC test was just barely a hint of pink. 1 drop turned clear .5 ppm CC.

Losing 5 ppm of FC over a 11 he period too much. Should I raise cya? If so can I use the 3 trichlor pucks that I did have in there when I was out of town or should I dissolve more powder?

No, leave cya alone. Assuming you tested correctly keep slam going until it holds better then OCLT would be what to base DONE on. You said earlier still cloudy so that means your not there yet.

I must have over shot my chlorine in my last addition at 5:30 without realizing it. I just tested and it was at 22.2 I was shooting for 18. Oh well it's not going to hurt anything, but I will test at 6:30 tomorrow morning and see if there is any loss.

As far as cloudy, I'm wondering if thatspollenor dirt. Since input the sock over skimmer basket it's been collecting tons of first or pollen. In a very short period. I've had to clean 2 times I the last 3 hours.
 
Suggestion: Use 10 ml water samples for FC instead of 25. It will save you a lot of reagent. You multiply the drop count by 0.5 instead of 0.2.
