high cc

[swirlywater]

I just got my fas/dpd test today. I added CYA on monday.
FC=1, CC=7.5, PH=7.4, TA=110, CH=90, CYA=30
Using the test from my K-2005 last weekend my cc=0 as it did all but once last year.
could the high cc reading be false or is it because I am using a more accurate test kit?
I plan to start SLAM this evening. The correct process given my levels is to raise fc to 12 and hold till I get a 0 cc reading correct?
I plan on using bleach to shock.

Can I leave my solar cover on the pool while shocking?

Having a CC that high can point toward an ammonia problem, although usually the CYA is all gone when that happens.

Add enough bleach to reach 12ppm, and retest the FC and CC in 30 minutes and report back.

You need to hold that FC level until you pass the 3 criteria to stop the ShockLevelAndMAINTAIN Process.

Having the cover on can actually trap some of the CC so they are not burned off by the sun. I would pull the cover off during the day (you will get more heat to the pool) and put the cover on at night.

I was hoping you don't say take the cover off. I put the mesh back on to keep the debris out till the pool is open for the summer

 

[jblizzle]

If the cover is mesh, that should not trap the CC and allows some sun in. I was thinking you meant a solid bubble cover or something.

 

[swirlywater]

I put the solar cover on and the mesh on top. I was reading the ID-10T manual.

Having a solar cover on the pool can cause CC to accumulate even when nothing else is wrong. I'd remove the solar cover for at least until the CC level comes down to 0.5. Pools need to "breathe", and even more so when you have a CC problem.

I think my FC is 7 after 30 min.. Using my new. FAS/DPD. It was a very very faint pink till I added the last drop. I used 4 121oz jugs of 8.25 bleach. Going to the store now for more.
This is a ton of bleach

 

[JasonLion]

Definitely not ammonia. FC would be zero if this was ammonia.

I have never had a cc problem. The only thing I did new was add cya

Your first post shows a CC problem

 

[swirlywater]

I meant I never had one in the past or as of sunday. Added 2 more jugs of bleach around 1030pm. As of 1 am my fc is 10 and CC has not changed. I will update in the morning. When reading the FAS/DPD test should I be looking down in with a white paper under or through the side at a light. The pink is barely visible through the side but I can see a slight change if I look down against a white paper.

 

[jblizzle]

I would use white paper as a background. I do not like to have a back light.

 

[swirlywater]

In the am I have 2ppm chl and my cc is up to 11. What do I do? Keep dumping chlorine in? The pin k in my test is very light not like in the video online which could mean I have close to zero chlorine.

Just checking the basics...

You got 4 drops on the initial test with the 871 Titrant? Then, after it was clear, and you added the R0003, it turned light pink again? After that, it took 21 drops to make it clear again?

 

[swirlywater]

Yes. But after the 3 it turns bright pink

 

[Kiss4aFrog]

Looking down through it or from the side with a white background is best.

Keep up the SLAM, test carefully and brush often.
Can you post a photo of the water ?

 

[swirlywater]

I just left for work without adding anything to see what you guys had to say. The water is crystal clear, I vacuumed last night for good measure. I can check back in at lunch.water temp is 49.

After 3 what does it turn bright pink?

 

[swirlywater]

way brighter than after I initially add the DPD. That is why i was asking if i was reading the test correctly. I haven't re-tested the CYA, but after reading all morning I am going to test FC, CC, and CYA, raise the pool raise the pool to shock level using the pool match calculator, re-test after 30 min, then it will have to wait again till I get off work.
