Strange test results -- very high combined chlorine (CC)

[Themadczar]

I have 44oz of cya... Do i just follow the procedure here...
http://www.poolforum.com/pf2/showthr...Way-to-Add-CYA
All 44 oz at once?

Also, these are my chlorine levels... Does this make sense?
5/29
5pm fc is 6 ppm, cc is 5 ppm
8pm added 96 oz. 6% bleach
10pm fc is 5.5
5/30
7am fc is 7.5, cc is 2
7:30pm fc is 2.5, cc is 7.5. Then added 384 oz bleach
8:30pm fc is 9.5, cc is 5
5/31
7am fc is 4.5, cc is 9
6:30pm fc is4, cc is 10. Then added 384 oz bleach
10pm fc is 5, cc is 12.5
6/1
7am fc is 5, cc is 11
6pm fc is 14, cc is 5
Numbers seem to be all over the place.... Not sure what to do now.

And finally, another question... Sounds like my pump motor is going bad (getting louder, whining noises, and hot to the touch). However, I cannot seem to determine the hp of the motor so I can get a replacement. Hayward Super Pump. Any ideas? Thanks yet again.

6/1
10pm shut off pump
6/2
8am fc is 14, cc is 5. Started pump back up (still loud)

There should be a label on the MOTOR (the hot part). There also should be another label on the pump casing (the part that has water in it). If you can post photos of both labels with Flickr, Photobucket, Webshots, Picasa, or Facebook, we can probably work out what size motor you have.

[Themadczar]

I reposted the motor question in the pool equipment section with more details... I did find a model # on the motor (sp2600zlc) but after searching the web, i still cannot determine the hp. If that's still not enough info, i will post photos.

[PoolDoc]

Hayward motors will have a SP number, but for example, a SP2610x15 is a 1HP pump that gets uprated as a 1.5HP pump.

6/1
7am fc is 5, cc is 11
6pm fc is 14, cc is 5
10pm shut off pump
6/2
8am fc is 14, cc is 5. Started pump back up (still loud)
5pm pump motor seized
9:30pm fc is 10, cc is 4
6/3
8am fc is 5, cc is 10
7:30pm fc is 12, cc is 3.
Why are the fc and cc levels fluctuating so widely when the last time I added bleach was 5/31 at 6:30pm? It seems that in the morning fc is low and cc is high, but in the evening the levels flip to high fc and lower cc... And how does fc jump from 5ppm in the morning to 12ppm in the evening without introducing any chlorine? I'm just not understanding.

Still working on getting 1) a new motor 2) dichlor... In the meantime I added 2 more gallons of bleach tonight and vacuumed with a catfish to clean up some debris and move some water.

[Themadczar]

Update... Pump motor replaced and running again. Reagents delivered (ran out of 8071 already). And i have dichlor. Back in business.
Added 2lbs dichlor last night.
Tested at 9pm tonight.
Fc=4.5
Cc=10
Ph=7.2
Ta=300
Ch=350
Cya= about 10 (too low to measure, but some is present now and the 2lbs of dichlor should amount to 9.6ppm)
Added 3 more lbs of dichlor tonight.

Retested at 10pm
Fc=6.0
Cc=19

I will retest in the morning... Anything else I should do?

[Themadczar]

7:30am
Fc 3
Cc 15
Very frustrating.

If you'd like to work up an estimate of how much chlorine will be required to clean up your pool, perhaps you could try: Bucket testing for chlorine demand.

Be calm. Frustration and impatience very often drive us to look for a "Magic Fix". "Magic" is never what it appears to be and in a pool usually makes the mess worse and the cleanup longer and more expensive.

How are you testing for CC? Your numbers are bizarre. How does the water look?
