Outdoor green pool problems

[Richard320]

Cloudiness is probably still dead bleached algae carcasses.

It can take days and days and days to get it all out.

Yor TA and Ch readings aren't so high that I'd suspect them of reacting and clouding the water.

Richard, Thanks for the responses.
It is still cloudy last night, today. I understood that my entire pool should filter in 10 hours or something like that, so thought any carcasses would have filtered out

Do you think Floc would help? Or do i just leave as is and wait, wait, wait...

If your water is still cloudy you should still be SLAMing according to the process. In the previous post you mentioned that you stopped adding chlorine. Are you back to SLAMing or having you stopped since the 22nd?

 

[outdoor]

i stopped, since 14 days of slamming and no loss of chlorine and CC is .5 seems like it should be enough.

today

FC is 18ppm
CC is 0 or .5ppm
Alk 130
pH 7.5 (don't know if that is accurate given the FC level)
CH is 180
temp is 73
salt 3600

You are good to go on two of the three criteria but it looks like your pool is still cloudy so back to SLAMming!

did Overnight Chlorine loss test last thursday night. And the loss was 1ppm and cc .5 so stopped adding liquid chlorine. Went away friday night for weekend. Put pump on timer to run 10hours a day through solar panels.

Came back yesterday water is somewhat clear, can see bottom, but not crystal clear.

Temp was 75
FC 18
pH 7.5 (don't know how accurate this is given the FC)
CC .5
ALK 130
CH 180
CYA 30-40 (difficult to test. if i put on white paper about waist level seems to be 40. If i just hold it in my hands at waist level seems to be 30)
Salt 3600

So could the Alkalinity being high cause the clarity issues?

Have you been doing the CYA test in bright sunlight with the sun to your back?

 

[duraleigh]

Sorry to glom on, but that pool is not clear. Look at other pics here on the forum.

The resolution on the CYA test is plus or minus 10 ppm so I would leave it alone.

ok but why would i still need to SLAM it my chlorine is not being used up and cc is .5 or below? Actually when i look closely at water there are a lot of tiny air bubbles, that could appear as cloudy could it not?

There are three criteria. Clear water, CC of less than .5 and passing the OCLT and you have met two of three unless that pic is misleading. Look at some of the other pics on here and you will see how clear it can get!

Well in essence i guess i have been slamming because my FC is still above 16 but going on tomorrow will be 21 days, there is no way it should take 21 days to clear a pool and have chlorine that high, especially since i believe any algae was gone last weekend. It must be something else causing it?

There are apparently 100 reasons for cloudy water.

 

[nismostate]

Have you checked the stairs for algae? Behind lights?

 

[duraleigh]

The SLAM process depends on enough FC held continually to clear a pool and proper filtration to clear the water. I assume you successfully completed the OCLT to eliminate any chance there are remaining organics in the water.

Perhaps there is something not working properly with your filter.

 

[bridgman]

Is it fair to say that while you *may* be able to end the SLAM once CC and OCLT say that nothing is being actively killed the time between CC/OCLT passing and "clear" is usually only a few days and so it's normally safer to continue the SLAM until all three criteria are met to avoid having algae grow back and waste all the bleach you poured in during the SLAM ?

I guess outdoor's question is "if the filter doesn't seem to be doing *it's* part, how long should you continue the SLAM after CC/OCLT both pass ?

 

[techguy]

I can't see you signature via Tapatalk but I don't remember seeing if you have a sand flilter or something else.

If you have a sand filter, going from this milky blue white to clear can take a week of 24/7 filtering.

iIRC, you are still losing more than 1 FC overnight. If you are, all the filtering in the world will not get you clear, you still have actively growing and recently dead algae (white cloudy stuff). I equate it to passing another car, if you are going 26 and trying to pass a car going 25, it's going take a long time to pass. You are technically passing the car but it would be more effective if you sped up. Cleaning the pool is the same way, you need to accelerate with good steady SLAM high FC to pass the always growing algae

OK so i have a cartridge filter, not sand. Before i put the stairs in i sprayed and scrubbed the whole thing with clorox.

Someone previously posted that you only have to clean filter when pressure is up20% from normal or something along those lines??? So i have not been cleaning the filter since the pressure has not changed. But yesterday i decided to have a look and it was quite dirty and had a lot of sand in the bottom of the filter. so cleaned that out. Water seems a better this morning, will see how much better by tonight it gets.

 

[outdoor]

Finally a clear pool. So i broke down and added a clarifier last night and this morning it is clear. I believe that all along whatever was causing cloudiness, dead algae or something must be too small to filter out and was not filtering. I should have added it first thing and i suspect my pool would have been clear within 1 week rather than 3 weeks

FC 12
CC 0
Alk 120
CYA 40
CH 160
pH 7.5
salt 3500
temp 80

Yep, we recommend cleaning filter when pressure increases 20 to 25% over clean filter psi. Since you found your filter 'quite dirty', maybe you need a new filter gauge.

You said the water seemed better after cleaning the filter, which was most likely the cloudy issue, imho. Clarifiers can work well when they work, and when they don't they just waste time and money.

Let's see a pic of your now sparkly pool

Hard to see fully since it is raining but here is what it looks like
