cloudy water

Postby vahj » Wed 04 Apr, 2007 12:51

Two weeks ago I added Power powder plus and my water is cloudy since.
Checked DE filter if OK. Added First aide clarifyer, no improvement.
FC 9, Ph 7.5, Alk 125, CH 270, CYA 50. 16,000 gallons concrete pool.
Any ideas.

Power Powder Plus is granular chlorine repackaged. The usual reason for cloudiness following application would be calcium undissolved. However in your case this does not appear to be the case as the CH is reasonable.

I note the chlorine reading is still 9. Assuming this is not a typo and the pool is outdoors then either you added so much chlorine it has taken two weeks to come down or there is not enough filtering happening to get all the water into the UV zone for reduction of chlorine.

There is no chemical reason I can see on the data posted for this pool to not be clear. The TA is higher than I would like, but not to the point of creating a cloudy pool. You could try adding acid until this reads about 80-100 this will assist in improving the clarity.

Cloudy is subjective. Can you please qualify cloudy according to this criteria:

1: Cannot see my hand with my arm in pool
2: Can see my hand but it is hazy
3: Can see my hand and it is quite clear but the body of the water looks hazy
4: I can see x steps down out of y
5: I can see my automatic cleaner in the deepend but cannot make out its features

I took your advice and drop two pints of muriatic acid in the pool,
last night. This morning the water is beautiful,clear.
Thank you.

could acid be what we need to add to make it clear. it just isn't clearing. It's driving me crazy. It's the "I can see my hand but it's very hazy. We have done everything we have been told.. I should mention that the pool is not average, it is a 24 ft pool.. which generally has around 13,600 gallons of water.. but it's not the average 4 feet deep. It's actually only about 3 and a half feet deep. So, that could make a difference. I think they just didn't dig it down far enough... but i really don't know how that works.. but it doesn't matter. i just want to get it clear.

What are your parameter readings? One solution does not fit all.

what are the parameter readings? And I will tell you. I don't know much about this stuff yet.

Posted on: Sun 15 Apr, 2007 17:53 Subject: Desperate about cloudy water

--------------------------------------------------------------------------------

Hi everyone

New to the site and desperate.

We bought our above ground pool in jan this year and had it put in the ground. We've had two weeks of clear blue water and ever since then all we've had is CLOUDS.

We've tried running the filter for 36 hours, continual cleaning of the filter, flocculant (which just complicated the problem), borrowed a barracuda (which keeps hugging the steps!), shocking the pool with chlorine (we use the granular type).

Now my own theory (from research undertaken) is that the cloudiness represents calcium residue from the granular chlorine we keep putting in the pool. The PH and Cl levels are good in the pool. Visibility is poor. We have wedding cake style steps and can't see past number 2 step.

If calcium residue is the problem, how do I cure it? running the pfilter continually doesn't seem to clear the problem.

We're desperate. Our pool has cost us a lot of money and we're not very happy! Can anyone help.

Feeling like cleopatra in a milk bath ....

Yes, the calcium may well be from the granular chlorine. Or, if you're topping up the pool with well water that may be the source.

Get your water tested at a pool shop and post your results here and we can give you a diagnosis.

Okay so I took a water sample to the pool shop and here's the results:

TDS 1000
Stabiliser 8.0
Free Chlorine 0.4
pH 8.0
Total Alkalinity 50
Calcium hardness 284

I'd be interested in your thoughts .... and thanks

PS Have an above ground pool in the ground hence vinyl, 69000 litres chlorine pool
