Can’t get rid of what looks like sand at bottom of pool

[sande005]

The filter will catch it. If you have a picture of an inlet, we can advise on the adaptor needed to get the hose to fit.

Pictures of the "sand"?

 

[kvazquez2006]

Yes, get the good test kit.
If the "sand" poofs up into clouds when disturbed - it is dead algae. Currently you likely are growing more, so an endless cycle of filtering it out, and then more replacing it.
Do as Texas Splash advised right now. When your kit arrives, the critical numbers will be the CYA (stabilizer), Free Chlorine, and Combined Chlorine. For the Cl, use the test involving powders and drops.
Visit your local WalMart and get several gallons of Pool Essentials liquid chlorine. Once we know the numbers, we can guide you on how much to add, and how often to test, to permanently knock it all down. It will be a sustained effort, not a one time event. Read up on the SLAM method in the Pool School here.

Here are the number with the test kit suggested by Texas splash

Cya 70 ppm

Fc 9 ppm

Cc .2 ppm

Ph 7.6

Calcium hardness 260

Total alkalinity 275

Glad to see you got a good test kit. I think now would be a good time to do anOvernight Chlorine Loss Test. This is a good test to see if you have algae brewing. Your TA is a bit high, but let's focus on water clarity and making sure you don't have algae before addressing the TA.

Sounds good. Thanks for the help

After dark still FC 9ppm

 

[Texas Splash]

So from 9 pm with an FC of 9, you would hope that the FC test this morning (before the sun rises) is no less than 8. If it's below 8, you failed the OCLT and would nee dot go into the SLAM Process.

 

[kvazquez2006]

Ok we have 8 ppm this morning before sun up.

 

[kvazquez2006]

Actually at 8 ppm I still saw the ever so slightest tinge of pink floating on top an when I put in drop 9 it was completely clear

Drop 9 would be 4.5ppm. Got a typo there?

Oh then I had a typo yesterday as well. It was 9 drops. Oops still learning how to use kit. Thank you

It was always 9 drops. I didn’t read directions correctly yesterday

 

[kvazquez2006]

Actually I looked at the instructions again and for a 25 ml sample it is 1 drop = .2 so wouldn’t 9 drops be 1.8 ppm?

Yes, but you should be using 10ml sample. Theres no need for the 0.2ppm precision.

 

[Homebrewale]

If you are using the 25 ml sample and your FC is 1.8 ppm, your FC is way too low. The minimum FC for the CYA level of 70 ppm is 3 ppm and target is 5-10 ppm.

 

[sande005]

Better get 1 1/2 quarts of liquid added right now.....you need to be in the 8-10 ppm range. (5 is bare minimum, 8-10 gives you some buffer for what burns off later in the sun).

 

[kvazquez2006]

I did That pool math app is a life saver

 

[kvazquez2006]

Ok here are new numbers
Cya 50
Fc 6.5ppm

 

[kvazquez2006]

Can I cover my pool while I am trying to get rid of dead algae? It looks better today.
