Cloudy water after adding Bleach

[mkohr]

I went away on vacation a for a few days. When i got back the pool looked perfectly clear, So figured i run the tests to to be safe. MY FC was 0.0 and CC was 1.5. So immediately panicked and dumped 1.5 gallon of bleach (12.5%) in the pool . The pool became extremely cloud within minutes of adding the bleach.
What caused this? My thought was algae bloom had started so i started doing a SLAM on my 2nd day now its clearing up but still a bit cloudy.

That's odd, but I would hold the SLAM value until you pass all SLAM criteria. One of those being clear. Let us know how this comes out.

Yeah I thought it was odd too.... When I saw cloudy I could barely see the drains in the deep end after 10-15 minutes of adding bleach.

Here's a thread from it happening to someone else. I don't know your other test levels, but perhaps it might explain what just happened to you: Pool got cloudy after adding bleach

Ph and CH in line? I'll be the first here - full set of test results please?

I wouldn't think adding 8-9 ppm FC would cause any scaling or precipitation.

EDIT - Texas found the post i was thinking of. Thanks.

12.5FC
1.5CC
90ALK
300CH
8.2+ PH dark red n off the chart!

Pool is clear now though

Good it cleared-up for you. But there are a couple items to watch based on your latest readings:
- PH should be between 7.2 - 7.8. If you need to SLAM (a possibility), it should be closer to 7.2
- CC of 1.5 is over our recommended <=.5 This indicates you have some organic material in your water and may using-up FC.

So even though your water is clear, there may be something trying to brew. You might want to consider lowering your PH to 7.2, and this evening do an OCLT as instructed HERE. If you fail the OLCT by losing more than 1 ppm FC overnight, it's time to SLAM.

Yup Texas splash I was thinking the same thing.

FC loss was 1.5 and CC was .5 I suspect I will pass SLAM tonight. Oh yeah got my ph down to 7.2 ish

As others have stated, you need to get your chemistry fixed ASAP. I think your cloudiness was Calcium Carbonate. If it was, you may see the cloudiness again, as you correct your pH.

All my numbers are in line now with the exception of a little too much FC loss last night. Not sure what you are referring too?
