Pool still cloudy white. Been a week today... This stinks.

[Lawrosa]

Yeah. Sand is one yr old. New laterals from last yr. Took apart, sand is good and all there. Took hose and stuck it in to clean it good. New spidergasket. Pressure rises overnight 6 psi or so on high, low goes up 2-4 psi, but on low output is really reduced so I backwash. On high it seems to stop before 20 psi. Starts at 12psi.


Just tested pool.

FC 2
Added 5 drops of r3 looks inbetween 2 and 3. 2.5??? TC 2.5 ????
Is that .5 CC???
PH 7.2. Orange color. One color above 6.8
Alk 80. 8 drops to change from green to red.
Hardness like I said I have this kit. It changes pink to blue in one drop. 17.1 ppm or 1 gpg.

CYA is at 30

What else should I test for?
What defect should I be looking at with the sand filter? I see nothing wrong. The only thing is where the valve sits on the riser/lateral. Is there a O ring. It looks like the valve just sits on the pipe. Its tight. To get the valve off you need to rotate it to get it off. Otherwise the laterals want to come out.

With a smaller pool, is there just one return and no floor drains? Is the cloudiness mostly in the deeper water? If so, then poor circulation could be a problem where pointing the return downwards (or diagonally downwards) and brushing can help stir up the cloudy water to get it to the skimmer and into the filter.

Also, you could try adding some DE to your sand filter to improve filtration though your first post sounded like you tried that. You first note the PSI reading on your filter (with the pump running, of course), add 1/4 cup of DE in a bucket of water and pour it into the skimmer and then wait a couple of minutes, check the PSI reading on the filter, add another 1/4 cup of DE, repeat, until the pressure on the filter rises by 1 PSI. This should not take more than 1-2 cups of DE, probably less in your case since your filter is smaller.

Hopefully Ben will have some more ideas since he wrote that there are 100 Reasons for Cloudy Swimming Pool Water!

One return. No floor drain. AG pool. Can see 6" down. Cloudy all the way. Added DE. 1/4 cup DE adds 1 psi. It rises 4-6 psi in 12 hours or so.

Would have called just now, but no fone in your user profile.

Still just sounds like massive dead floating algae, and the typical problems that result when you try to clean that up with a really typical, really poor, AG pool filter setup. In general, AG pool sand filter and pump combos are TERRIBLE at cleanup.

There is another issue. I don't know which clarifier you used, but overdoses can make smaller particles essentially un-filterable. Add up your TOTAL clarifier use over the last week and compare it to the maximum dose on the bottle. If you are over, or close, that's probably a contributing factor.

HOWEVER, it sounds like you ARE filtering if you use DE or the cartridge.

If you are willing to wait another week, turn your filter on high, leave the cartridge in (get a new one if you can) and filter away. Do NOT add more clarifier. DO keep the chlorine high, to kill any remaining algae and to break down (hopefully) any excess clarifier.

If you want a clear pool sooner, go get a new DE filter or drain and refill. In fact, with just 6200 gallons, it would be cheaper to drain and refill.

Best wishes.

PS. Just had a thought -- is the sand in your filter LABELED filter sand? Some dealers have sold coarse sandblast sand as a high margin substitute. If so, you need to replace the sand you have with real filter sand. Doing so won't affect anything with the cartridge in place, but long term, it will.

*********** I have two filters. The original was the powerflo matrix 100 sq ft cartridge. The pump is a one HP two speed. I run on lo 90% of the time. When I needed a new cartridge one yr because the cartridge clogged in hours, I opted for a sand filter I found on a list site. It was the 166T hayward. Free. What I do is use that for heavy spring clean up, then go to cartridge. But last yr I just kept the sand running all yr. This yr I started with the sand. Since it was not cleaning, I kooked the cart back up. But the cart cloggs too fast and has thin spots where I can see daylight. So I am just running sand now.

******** Clarifier I used leslies ultra bright. 2oz, 2oz and 4 oz on three different days. Says 4 oz treats 10000 gal. I have not put any in, in a couple of days.

HOWEVER, it sounds like you ARE filtering if you use DE or the cartridge.

************* I am using DE in the sand. 1/4 cup raises it 1-2 psi.

********* Getting a cartridge Tuesday. Its shipped from CA. It was 49.00 on line. Pool stores has to order at $125 bucks. This is a Unicel. They say they are the same or better quality.

If you want a clear pool sooner, go get a new DE filter or drain and refill. In fact, with just 6200 gallons, it would be cheaper to drain and refill.

******** Dont want to drain, but with all the backwashes and refilling, I think thats why its not as cloudy, but it is really cloudy.

Best wishes.

********** This is real filter sand. Its the white middle of the road stuff. The choice was sand. middle of the road sand, or zeolite. This is a white sand.

My # should be there.

Sounds like you just need some patience, then. I'd offer to loan you some of mine, but I'm fresh out! ;-)

Hi all!!!

Just a update. New cartridge and pool still cloudy.

Pressure does not seem to build up in cartridge. Started with new cart at 14 psi. Ran on high all day and low at night. Woke up and put on hi. Should of built pressure if it was catching stuff correct? Pressure actually went down...12 psi??? Does not make sense.

Well I have sand filter hooked up after cart.

What I do is remove cart. Backwash sand, add de to sand to get pressure up 1 psi. Let run 15 min then install cart. I have two filters going.

I have patience but this is getting out of hand.

I do not want to drain, and especially dont want to add flock.

Any other suggestions???
