Last night FC 6. Today 1 and a bit cloudy.

[Pollock]

So what the deal. It's really hot right now. Pool was 96 degrees on it's own. Does the hot water eat chlorine. My stenner injected 2 ppm today as well provided it was working properly.

Normally it only loses 1.5 to 2ppm a day covered. It was covered today all but an hr or so.

FC 1
Cc. Less than .5
Ph. 7.4
Ta. 110
Ch. 230
Cya. 30.

Added 1 gallon of 12.5 percent and the FC was 11 when I tested last. It's not real cloudy but it's not clear either.

Sounds like you are on the verge of an algae outbreak.

Time to do a --> SLAM Process <--

I'd also leave the pool open a bit more often to let it "breath" a bit and let the sun help burn off the CCs.

Would 11 hr pump run time be to little when it's really hot. I left it on all night last night.

Warm water will increase chlorine demand, you are close to having a huge hot tub with that high a temp.

 

[YippeeSkippy]

The pump run time has little to do with it, unless you are running a salt water chlorine generator (SWG)?

You need liquid chlorine in there and fast. The super hot weather will surely help the algae reproduce and spread.

I have a client who has a huge above ground pool, it's 23000 gallons, and they keep it heated to 92 degrees from April through December. The pool's chlorine depletion is virtually the same as rest of my clients... it does not require more.

I think sunlight exposure, bather load and the general environment of the pool in general has far more effect than water temp. That's my observation anyway...

 

[Pollock]

Then obviously I have something going on even though the CC is not high.

CC is just one indicator- an insatiable appetite for chlorine is the real clincher.

Then obviously I have something going on even though the CC is not high.

You can absolutely have algae issues without much CC indication.

 

[Pollock]

So now what do I need to SLAM?

 

[Pool_Medic]

96 is approaching hot tub temps lol.

higher temps , plus flying pollen bombs, equals more chlorine needed imo

Yes to starting a slam, keep your chlorine at or above the targeted 11% of CYA.

Click the link I posted in message #2 in this thread. Follow directions to the letter.....and your pool can be sparkly clear and clean again!

Feel free to ask any other questions about the process after you've read the directions and have you test kit at hand

So now what do I need to SLAM?

If your CYA is still 30 then you need to raise your FC up to 12 and HOLD IT THERE, until it can be proven to hold overnight via the OFCLT.

You may need to increase your chlorine additions to hold it at 12, especially during the day, since the CYA is only 30.

If the "Re:Last night FC 6. Today 1 and a bit cloudy" was your OCLT, then you more than likely have the start of an algae bloom! A SLAM is in order for sure. If the two tests were not after the sun went down and then before it came back up again in the morning, start a SLAM until you can do an OCLT tonight just to rule out a filtering issue. The slightly cloudy observation means more than likely a SLAM is in order anyways. Good Luck !!!
