Mustard Algae

[PoolDoc]

Looks like iron, alright. You can take a sample from the creek, add a bit of bleach, and see if you get similar fluff to test and see if the creek is iron filled.

But, I don't see why it matters, as long as you don't fill the pool from the creek.

The brown dust in the other picture just looks like dead algae.

If it's algae then why is it not clearing? I've maintained at least 15ppm "no less" for more than 10 days. My filter has been running 24/7 and I've brushed and vacuumed to waste every single day :-(

Do you think it's mustard? Could I have both algae and Iron in the water? I'm seriously ready to throw in the towel. I don't know how to keep this water clear every time I shock with bleach my water turns green. I'm having a pool party on May 7th and feel like it's not going to be clear by then and my kids are driving me crazy to swim.. I'm about ready to hire someone to fix it (sorry I'm venting)...

Tears :-(

I have had the water tested many times for metals.. Including today just to be sure.. It all comes back at 0. I've been to two different stores to have it tested and they all come back as negative. I don't know what to think.. No one knows what is wrong with my pool. Everyone says its algae.. I treat for algae and it's still green. I let the filter runs for weeks NON STOP and it's still green. I'm seriously at a loss... The pool store gave me a floc today to put in the filter b/c I went up there raising heck... They took care of this pool for almost a year.. They gave me a written letter when we purchased this house that this pool was in good working order. The guy who was doing the cleaning vacuumed HUGE acorns to waste--which caused a HUGE clog and my skimmer would no longer work.. We had to fix that. Then they had me dump shock in that turned my water green... SWAMP green.. Then they sold me Yellow Out and that made it worse.. Then they sold me Phosfree.. Which made it worse!!! Then I changed out the sand and here I am.. It's still darn green. I've tried the all bleach method and that's not working either... I can't even imagine the amount of bleach that I've dumped in this pool.. My garbage guy probably thinks we are a bunch of weirdos since half of my garbage can is full of empty bleach bottles twice a week... I seriously don't know who to trust or what to do. I've put so much money and crap in this pool in a matter of 4 months and I feel like I've been taken advantage b/c I'm a new pool owner. Everyone is saying something different.... ARGGGGG!!!!

Sorry about venting!

We are getting our source of water from the hose. Our house was built in 2003 so I don't think we have pipe problems. Also, I have several neighbors that have pools and are filling from the same county water and they don't have green pools and or iron problems. I've looked under the house and all I see is regular pipes (plastic white ones) so I'm not really sure. But the liner was replaced in this pool last year in Feb so I know the pool water is not that old and from all the vacuuming and wasting I've pretty much refilled this pool in the past 2 months.

I have not tested the creek water.. But like pooldoc said I'm not using that as a source of water to fill. But very interesting to know that I have such high iron content around my house. I did check the creek today and the part that was orange is completely normal now-- STRANGE. I guess I just had SO MUCH chlorine in the waste water that I had a major reaction with the iron in the creek. I did try and test the spring water from under the pool by adding chlorine to the test water.. I didn't get any orange/brown/green from it.

I don't have any chlorine test stuff left. I've order a refill but it hasn't made it here yet. So I'm not sure about what I'm losing if any at night.

Here are my latest results.. I haven't added chlorine since I run out of testing stuff. My test 3 days ago read 15.5 so these are my numbers (from pool store) as of 5pm today.

-- semi closed thread! No posts here but andrea's and mine, please!! --

Hi Andrea;

I understand your frustration, but you are going to have to be patient. I mean that: if you are not patient you WILL make your problem worse! This is a common issue; you are not alone. I've written long pieces before on the secret pool owner miracle additive: P.O.P., or Pool Owner Patience; I won't reproduce them here.

Part of our (my) problem is I can't tell what's going on, because you have done, and are doing so much. Back off, slow down, and STAY AWAY FROM THAT STORE! You've got metals, possible algae, and a potpourri of chemicals in your pool, and God only knows what that combination will do. Again, I mean precisely that: there is no one on earth who understands and predict how that mixture will behave.

And without divine revelation, I have no good idea about what, of all the things you've added, is STILL in your pool. What I do know is that CHLORINE, TIME, and SUNLIGHT will remove many of those things.

You've GOT to stop going to that store. Not only are they selling you stuff you shouldn't use, I can look at your test numbers, and tell that the test results are bogus. 10 years ago, those numbers could only have come from a BioLab "Alex" system. Now, there are probably other copy-cat systems that sell chemicals by delivering bogus test results. The bottom line is, I not only have no idea what's in your pool; I don't know what the chemical conditions in your pool are, either.

You need to remind yourself of this every day: "The longer my pool is screwed up, and the more frantic I get, the more money my pool store makes." Whether they know it or not (not all do) , pool stores DEPEND on stringing you along for their financial well being.

You've GOT to back off, and work this through, one bit at a time. BUT, keep your chlorine high.

If your liner is slippery, you may have algae. If it's not, you probably don't . So I have 6 questions:

1. Is your liner slippery, or not?
2. Is your pool clear, or not?
3. Are there orange or brown stains on your steps, and inside your skimmer, or not?
4. Is brown dust still dropping to your pool's bottom?
5. Have you ordered a Taylor K2006 (links in my sig) and if so, when will it arrive?
6. If you fill the pool with same water that is in your bathroom, tell me what color the INSIDE of your toilet tank is. (Brown, orange, dark brown, light tan, etc.)

Meanwhile,

1. Keep filtering 24/7
2. Brush your pool every 2 - 3 days; vacuum as needed.
3. Purchase a cheap OTO testkit (Walmart!)
4. Add 4 gallons of chlorine every night -- unless OTO shows dark orange.
5. Let me know when your K2006 arrives.
6. Do NOT do anything else, except clean your filter, but ONLY if it needs it.

There is one more thing. If you can buy, or beg, a small amount of DE (diatomaceous earth) filter powder, you can dump some into the skimmer, and then watch the returns. If it shoots back into the pool -- your filter is messed up. You might have been sold the wrong sand; your sand might be gone, or several other things. But, a filter than won't catch DE, won't catch algae or iron dust, either. Home Depot has it online for $20 for 25#, but they may have a smaller container locally. Alternatively, if it's algae dust, a broken filter will let a stream of dust BACK into the pool if you vacuum up a pipe of dead algae dust.

PoolDoc

PS. There are several possible reasons for clear green pool water that I know of, and that could apply to you. One involves iron in an odd condition, but it still comes back to the fact that I don't know what's in your pool, whether your filter is working correctly, or what your actual pool test results are.

PoolDoc,

Thanks for responding. This is Andrea's husband, Tim. She's finally handed the reigns over to me and I can assure you I have the patience your looking for. I don't think there's as much chemicals in our pools as you've been led to believe, but we'll walk through it one step at a time to be sure. Honestly, we've been using only bleach for at least two months now. About two month ago after reading one of your POP pieces, we shocked with only bleach with chlorine levels over 15ppm for 10-14 days brushing every other day at least. While the pool was clean, the water was still greenish-brown and cloudy. I began to question the filter. I had a pool maintenance guy out who said it looked as if anything that may have been in the pool was dead but the filter was not filtering. He added some DE to the skimmer but it shot out the jet, and he recommended we replace our filter sand (no additional chemicals added). I purchased 125 lbs of good pool filter sand from a local/accredited pool store and replaced the sand in the filter myself. I made sure to clean and inspect the fingers in the bottom of the filter and all checked out good. Refilled with sand and ran the filter for days with no real change to water color/cloudiness. I decided to turn off the pump as I had seen once before that dirt/debris sank to the bottom of the pool when the pump was not running. Sure enough, after 4-5 days everything that was in the water settled out. I was able to vacuum to waste and for a few days I had a clean pool. Unfortunately days later, in late March, the pine trees rained down the pollen as they do every year and the top of our pool was covered with yellow dust. To boot early spring sprigs (for lack of a better term) began falling from nearby tees and again we had a pool that was cloudy/green by time the pollen and tree debris stopped raining down. For the life of me, I'm not sure how previous owners dared to keep this pool uncovered during the winter months. There is so much debris that falls from nearby trees, my wife and I have skimmed or vacuumed with a leaf bag vacuum attached to the hose almost every day since November. Now on to your questions:

1. Is your liner slippery, or not?
No, I don't feel it's slippery.
2. Is your pool clear, or not?
I would say the pool is clean but the water is not clear. I can see the bottom of the deep end which is about 8' and the shallow end looks pretty clean. The water has a green color, but as I'm a new pool owner, I can't determine if the water is cloudy and the blue liner makes the water look green or if the water is actually green. When I take a pool sample using a small pitcher, the water looks clear in the bottle, not green.
3. Are there orange or brown stains on your steps, and inside your skimmer, or not?
No, there are not distinct brown or orange stains on the step or inside the skimmer. I would say they are a dingy in color, but not sure if that's from age (pool is 7 yrs old) or from a metal in the water. I think it's important to note we live in GA so even the toilets will get a pink/orange ring if not cleaned regularly. We do have other neighbors with pools though and they don't have green water nor do they treat for any metals from their tap water.
4. Is brown dust still dropping to your pools bottom?
I would say the bulk of remaining dust/dirt/organic material or metals are contained in the cloudy water.
5. Have you ordered a Taylor K2006 (links in my sig) and if so, when will it arrive.
Yes, we ordered the Taylor K2006 and have been testing for more than two months. We've recorded many of our tests so I can send them to you. We recently ran out of the Chlorine test solution, but have ordered more which should be here very soon.
6. If you fill the pool with same water that is in your bathroom, tell me what color the INSIDE of your toilet tank is. (Brown, orange, dark brown, light tan, etc.).
Yes we fill our house water. The tank is orange/brown. I can send a picture if it will help.

I have been interested in adding a floc, so I did add 5 oz. directly to the filter tonight. I want to say my filter pressure has kept me guessing as well. With only the skipper open and all other valves closed, my pressure is at 10 PSI. When I open the main drain at the bottom of the pool, it raises to about 12 PSI, but when I open the outlet to far side of the pool, PSI drops to 1-2 PSI. To add the floc, I used mainly the skimmer, but opened the main drain and outlet valves only half way keeping filter pressure at 5 PSI. The pump has now been running for 6 hours with no pressure increase. I'm beginning to wonder if my sand filter is actually catching anything. Please read over and provide your thoughts.

Thanks again,

Tim

I failed to mention in my previous reply that we have again been using only bleach with Chlorine over 15 ppm for the last two weeks (min 14 days while brushing daily). You can probably go back through my wife's thread to see how that transpired, but for the last couple of days the free chlorine wasn't dropping overnight. As I mentioned we are now out of test solution so we have purchased more. Chlorine should still be over 15 ppm as I added 3 gallons of bleach last night after we ran out of test solution. Tonight is the first time I've added floc.
