Cloudy Salt Pool...Please Help

by Shari

My pool is 27 round, 54 inch ht. And alkalinity was zero and pH was 7.0.

Pool guy told me to add 10 lbs sodium bicarb slowly in a slurry then in 4 hours 10 lbs more. Did this and now my pool is very cloudy. I have a DE filter that is also very sluggish now.

In fact I tried to bump it and nothing cane out so now I fear all the bicarb clogged it? I'm set now to add 15 lbs ash next in 4 hrs then 2 lbs shock 4 hrs after that.

My pool WAS crystal clear prior too this but we had just killed all algea, shocked and shocked then clarified etc so I knew the balance was "off" so I took in a bottle for analysis.

This is what I got.


Thanks for the question Shari

I'd like to have your complete chemical readings:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper).

It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store.

The way you added the bicarb will raise the pH and might have some affect on the total alkalinity (TA). Also, you MUST wait for one full turnover of the water before testing or making another adjustment. This is normally about 8 hours.

You might take a sample from a spot that hasn't been treated. This will give you a false reading. If you make another adjustment you've just doubled up and may have caused a bigger issue.

You can raise the alkalinity
and pH using baking soda. I would recommend not using soda ash as the pH will rise on its own. If it's 7.0 or 7.2, leave it alone and focus on the TA. Don't buy any TA up or pH up as this is only baking soda. You can get this from your grocery store for 1/3 the price.

You raise the TA with the pump motor off. Add the bicarb straight into the pool and allow to sit for about 4 - 6 hours, then start the pump and allow for 1 turnover, then retest. This is where patience comes into play. Make adjustments in the evening then retest in the morning.

Pool Alkalinity

Total Alkalinity

Raise the pH with the pump on. Make a slurry and broadcast it around the pool.

Swimming Pool pH Levels

Pool pH

Again, if the pH is around 7.0 or 7.2, DON'T add soda ash. The pH is fine and will come up.

The bicarb may have clogged the DE filter. If the pressure is high, above 8 - 10psi over "just backwashed" pressure, you may need to clean the grids and recharge with fresh DE.

Before you possibly waste money to shock the pool, give me a complete list of chemical readings. As for the cloudiness, it will dissipate through backwashing and filtering, but it may take some time.

And watch the clarifiers as well. These kinds of products don't address the issue of why the pool is cloudy. It's just another expense you don't need.

Do You Really Need All These Chemicals For A Pool Or Are They Just Trying To Get Your Money?

Hope this helps.
