My beautiful green swamp that has turned yellow

[mdb_007]

so my pool is still cloudy and isnt clearing up , ive spent close to $200 in bleach, should I just drain and scrub then refill

That's an option certainly, but you'll have to make that call.

You have to be careful not to drain too much that would create an opportunity for the liner to float!

I have not re-read the thread, but it appears you have not finished the SLAM process. If you have zero to .5 CC and have passed the OCLT or are close, then you could try adding DE to the sand filter. Direction How-To in Pool School.

Also, have you checked your filter for problems? Maybe it is channeled and needs a deep cleaning. Here's a link:

[mdb_007]

the sand was replaced last month and the lateral pipes inside were replaced as well, could channeling occur with new sand

What size sand filter do you have...the info in your sig is about the valve and not the filter.

 

[mdb_007]

The Filter is 24" Hayward model no: S244T
Effective filtration area: 3.1 FT2

If the filtration rate is 62 GPM, wouldn't that mean that 6 hours is the turnover rate for the pool and this means it turns over 4x a day?
Is that sufficient?

 

[duraleigh]

If the filtration rate is 62 GPM

That's the design capacity of the filter. Pushing more water than that is inefficient.

It is unrelated to how many gpm your pump is actually pushing through the system......hopefully a bit less than 62 gpm.

 

[mdb_007]

I know the piping is 1 1/2" in diameter and there are 1 skimmer and 2 jets. from what I have seen online the max gpm for 1 1/2" pipe is 42 gpm, I know the pump is rated for higher than 42 gpm, but being that there is only 1 inlet from the pool to the pump, I think that the gpm getting filtered is 42


Also I attached a rubber hose to one of the jets and the water coming out is just as cloudy as water from the pool

What are your latest OCLT and CC results?

 

[mdb_007]

CC is 1 ppm which means I'm not done with SLAM, it was .5 for a day then jumped back up to 1.5 and now is down to 1
OCLT havent done yet

 

[linen]

Then keep with the SLAM process. Often the cloudiness is the last of the three criteria passed. Once you are passing the OCLT and CC<0.5 then you could consider adding DE to help the filter.

 

[mdb_007]

we are getting there!
here are current readings:

FC 13.6

CC 0.8

pH 7.0

TA 130

CH 200

CYA 40

I added enough chlorine to bring FC back up to 16

Just curious if the rest of the values should be considered now?

 

[linen]

All you really need to worry about or test for right now is FC and CC. The rest, if needed, can be adjusted later.

By the way, no need to use a 25 ml sample for FC. 10 ml is just fine and each drop will equal 0.5 ppm.

 

[Charlie_R]

Not until you pass the OCLT. Then start with the TA.

As your pH is reading on the low end of the scale, it is likely lower than that currently with you FC above 10.0. All you will have to do is aerate to bring that up. When it reaches 7.8, add MA to bring it back down to 7.2. Test your TA then, and if you feel it still needs to come down, continue the acid/aerate.

 

[mdb_007]

By the way, no need to use a 25 ml sample for FC. 10 ml is just fine and each drop will equal 0.5 ppm.

I have been using the 10 ml this whole time, just used 25 ml to get a more accurate value on CC

 

[linen]

Okay, really no need for 0.2 ppm resolution when measuring CC (or FC), but it doesn't hurt anything other than using up your reagents faster.
