Pool is cloudy green

Postby Help » Tue 29 Jun, 2010 18:31

Hello everyone, I have a cloudy green pool and can't get it cleared up, help please.

We have had the 24 foot round pool up here at the house for several years, and wanted to change the liner this year so last fall we let several leaves fall in it before we covered it up, so we had several leaved in it, but we have them all out I think.

I shocked it several bags when we uncovered it cause it was black, not good.

I have messed with it for 3 weeks now and still a cloudy green.

With the HTH strips with the 5 colors on it here is what I had.

I can't get the chlorine up.

Here is the numbers.

Total hardness was 200
Chlorine was 1/2 not sure of the PPM on that.
PH was at 7.8
Total Alkalinity 180
CYA was at 30-50

Read Defeating Algae and the how to on Shock Your Pool in the Pool School . Shocking is not a one-time addition of some chlorine -- it's adding enough to raise the chlorine to a high level and then adding more as needed to maintain the high level until the pool is cleared. You'll need a good test kit to be able to measure the high chlorine level -- either the Taylor K-2006 or the TF-100 .

I don't think I have an algae problem, the sides aren't slimy and when I backwash it the filter doesn't turn green, it really doesn't cloud up much at all.

I checked it with the strips today and it shows no chlorine, and the Ph seems to be down some.

What would you throw at it if it was yours?

I forgot to let yall know that I have the two tube tester but it's about a year old, and I have dipped it in the water and put the 5 drops in the Chlorine and the 5 in the PH side and it shows the same thing as the strips, low chlorine and high PH.

Will the high PH cause a green water color?

I'm going to throw a couple bags of shock in it in the morning and some PH minus and see what happens.

Any help would be appreciated.

I went away from shock because it was causing too many chemical problems going up and down so I am using liquid chlorine.

I remember putting in some PH and then shocking and my pool went to cloudy green as well. I have been battling no FC but until I can get my CYA down then I will address the chlorine loss issue.

My CYA is very low.

Got to do some reading on how to raise it.

If it were a clear green, then yes. High pH can precipitate copper ions that make the water look green and can also stain surfaces. Lowering the pH usually lightens that up and you can add a metal sequestrant if that is the case.

The cloudiness, however, probably indicates algae growth. It starts out as dull then cloudy and then green so it doesn't always look green to start with.

Get yourself a good test kit such as the Taylor K-2006 or the TF-100 and read Defeating Algae .
