HELP dealing with mustard algae!

[Watermom]

I would not use the tabs right now, just bleach.

What i wrote above:
"Each jug of 8.25% bleach will add 3.4ppm of chlorine. For now while you are cleaning up your pool and until we know your CYA reading, I'd probably aim for keeping the chlorine between 12-15. Also, run your pump 24/7 while you are working to clear it and turn your SWCG off.'

So, you test, then add however much bleach you need based on that info above, to get your chlorine level back up between 12-15. Once we know your CYA level, we may revise that recommendation but for now it will give you a target.

The yellow chlorine test is called an OTO test. If you click on the following link, it will take you to a chart that gives interpretations of colors that are higher than that kit can actually measure. But, you can use the colors to get an estimate of what your chlorine level is. When you are trying to clean up a swampy pool, you want to keep the chlorine in the very dark yellow/orangish range. http://pool9.net/oto-chart/

(By the way, when your chlorine level is over 5ppm, the pH test on that kit will give you a falsely high reading. So, test pH whenever the chlorine is lower than 5.)

Not sure about the sand on the seats. What size is your sand filter (how many lbs. of sand does it hold.) Sounds like your filter may not be working properly. To test it, buy the smallest bag of DE that you can find, throw a handful into the skimmer and watch the returns. If you see white powder shooting out, your filter is not working. If it doesn't shoot out, the DE may actually help your filter to filter better. More about that here: http://pool9.net/de-test/

Hope this helps.

Last question for now. Do I pour bleach thru skimmer?

[Watermom]

Yes, you can. That is always what I do for my pool. But, only do so if the pump is running.

[shannon2014]

Thank you-still had some algae this morning but not as much and haziness is clearing from the deep end.

[Watermom]

Glad to hear of the progress! Keep the chlorine level high and continue to run the pump 24/7.

Got my kit in last night - these are the readings I got this morning. Please keep in mind first time testing and I have been working all night
FC 22.5
CC 11.5
Ph 7.8
TA 200
Ca+ Hardness 100
CYA 80
Still had algae on bottom of pool which I vacuumed to waste. It wasn't alot -seems to be thinning out - not as many large clump areas. Any advice would be appreciated!

[Watermom]

I really doubt that you have a CC reading of 11.5ppm! Take a look at these testing demos: http://pool9.net/K2006-vid/

If you are still fighting algae, then you need to continue keeping the pool at shock level and brush your pool while the chlorine is high. Now that we know what your CYA reading is, we need to adjust your shock level per the Best Guess chlorine chart: http://pool9.net/cl-cya/
So, your shock level will be 20ppm. And, once you get this algae bloom cleared up, you'll want to make sure you always keep your chlorine between 5-10ppm. If you drop lower than that, it will come right back. (By the way, the "best guess" chart is also available through the tab in my or Ben's signatures if you ever need it and can't find the link I put above.)

Since your CYA is on the high side at 80, only use bleach from now on. No more dichlor shock or trichlor tabs. They both have CYA in them and you don't want yours any higher.

Did you ever do the DE test to check to see if your filter is working properly?

Hope this helps. Re-do the chlorine test after you watch the videos and repost your FC and CC numbers.

Yes, you can. That is always what I do for my pool. But, only do so if the pump is running.

Is there a different result or is it wrong to pour it directly in the pool in front of the jets?

Pool stores will have it. Many of the local walmarts (Dallas Tx area) carry this

The description is correct, picture is INCORRECT.
