Opening AG 24ft -Everything is wrong

[brianbo]

Hi,
First timer and posted in wrong forum but this is the right one but here 's my story, I live in MA. For 3 years everything great until last July. I think my well hit a new acquifer as I got a more iron in pool. In late Aug 2007 , pool company vac it out and had clean water. But, I added water and shock and same brown junk on bottom of pool ( iron or algae guess was iron no one actually committed ). Drought in Sept and closed it with brown stuff on bottom.
Cover collapsed in winter and opened yesterday. I added 5 inches of water 2 nites ago. Also yesterday, I bought and installed Hayward DE Grid 2420 and am using my 3 year old 2 speed 1/2 hp and 2 hp to run it. I replaced a sand filter. The GRID filter says to use a 3/4 hp though. I read WASTE documentation on DE filter: and will buy DE cannister tomorrow to put in the right amount. Unfortunately. it is too late to get the pool tech to show me as I started it already.
I am running pump at 2 hp but low pressure causes me to backwash and rinse every 2 hours and add DE. I will turn it off later tonite as there will be no return water. The pool guy said run the filter with METAL OUT for a couple of days to get the metals out (iron and manganese in well water). Once metals out, then potassium chloride instead of shock as he said they better luck with that than shock causing less brownr. He did say add Metal Out when no chlorine but I am impatient as TC = 1 and FC = 0,
3 years ago, my water was tested and iron was 10 microns and I have a whole house filter. DE is new to me as of yesterday.
My questions:
1) When I backwash/rinse the DE, the water does not look that dirty but each time I do the pressure and return are good? I am probably putting in wrong amount of DE after reading WASTE's write-up.
2) Question about WASTE's write-up- I have the GRID filter, your and Haywards directions did not say release the air valve but in the Bump part you said to release it. I know the filters are different but do you recommend releasing it for GRID filter as well?
3) The water is disgusting. It was black yeaterday but now murky and a lot less scumy. I know it will take time. I asked the pool guy if I should vacuum all the junk on bottom ( green slime but now I am afraid as I just read about green poop, ammonia, CYA ) .
Pool guy said to wait until I get water tested to vacuum but why wait?
4) Should I get a pump to match the recommended filter or will the 2 speed work fine with Haywrd DE GRID 24?
5) Absolutely loaded question: What do normal people do with 24 ft AG with iron, manganese in well water and need to add water to pool?

Sorry for the length of this but I was so disgusted last year. Everyone in area with well water said to get DE which I did and I know it will take time but.

I wish I could help but my knowledge of DE filters is limited. But if your filter is rated for 3/4 hp (not a real rating--it's max GPM that matters--how many gallons per minute the filter can take--and what's the max the pump puts out) and you are over-straining it, bad things can happen.

The brown stuff I get is either dead algae or pollen and usually ends in June. But you need a metal test and can either buy one from Leslies on-line or from TaylorTechnologies.com

For metals, again, I'm not the best. Mbar (Marie) is one of our most knowledgable members, and she usually can help diagnose metal problems and recommend a solution.

Meantime you need to post your standard test numbers:
FC, CC, pH, T/A, Calcium and CYA. If you have them, copper and iron and magnesium numbers as well. You should vacuum to waste as well.

Poconos or one of the pool dealers here can advise you on the pump and DE filter situation.

Don't give up! It's definitely solvable, and without a pool service to muck things up.

Regarding #5....I have an 24' AG with iron in my well water. In the future, you will need to add more Metal Out before you add well water to your pool. The key is to keep enough Metal Out in your pool to keep the metals tied up so they won't fall out of solution. Another tip is to add the water directly into your skimmer so that the new water goes through the filter before it goes into your pool. That way, most or (hopefully) all of the metal that falls out of solution will do so into the filter medium instead of onto the pool surfaces. That's a quick answer, and there is more to it....pH and cl levels also play a part....but metal issues can be managed without staining if you learn how. Read everything you can in the metals section of the forum. I'm not an expert, just another pool owner with a similar problem.

Mbar is definitely the metals guru here. She should be able to help you with your current metal problems, and avoiding future problems, BUT she will need you to post your test results. Do as CarlD suggested, get a complete set of numbers and post them, and the great folks here will help you solve the issues you have. It is absolutely solvable and you can do it yourself faster and cheaper than the pool service!

I went to pool store and got different these results as the owner was on service call.
I vacced to waste and a lot green and junk came out. I then brushed the walls which I should have done first. My pole broke and I jumped in to get the middle. It looks like the bottom is cleaner but you still cannot see it as it is green and brown.
Pool place #'s are
FC .3
TC 1.1
CC .8
PH 7.9
hardness 60
Alkalinuty with stabilzer correction 50
Cyanuric Acid 35 (is this CA or CYA)
They did not run the Copper, iron and Total Dissolved Solids
She said the copper was broken and there was no sense to iron as Cholrine was present (??) or something I cannot remember.

The filter clogged in 2 hours . I am going to need to add water if I vac again.
I still think I need to vac again.
Any suggestions would be appreciated?

Daisy11, when do you add the metal out before you add well water? ! cycle, 1 hour, 5-12 hours, etc.

[CarlD]

I would add lots and lots of chlorine--bleach or liquid chlorine. YOu need to get your FC level to 15. I would add 5 gallons of regular bleach or 4 gallons of Ultra.

If you use 12% Liquid Chlorine, use 2 gallons. Then, 8 to 12 hours later, add it again--but TEST it first.

[aylad]

Cyanuric acid is CYA....Calcium is CA or CH. And I agree with Carl--add your Metal Out, and then shock your pool, maintaining that shock level until it clears up. Keep your pump running, backwashing as you need to, and brush it at least once daily. With some patience, you can get it clear.

I Vac again yesterday but was in pool and forgot to put value back to filter from waste so I lost some water. The same stupid thing I did last year.
Pool is still greenish, cloudy and has brown sediment on bottom but cannot vac as water is low.
The test strip I used said chlorine was low so I added 2 different times at added 2 gals of 12%. I went to the pool store and they tested and my chlorine now is how. I might need new test strips as these strips #'s are not close to the pool store #'s.
Pool store #'s.
FC - 4.3
TC - 4.3
CC - 0
ph - 7.7
hardness - 80 ( CA?? and I have AG with vinyl liner so I do not care. Right?)
Alkaline w/Stablizer - 68 (I had 6 lbs baking soda and I will add 3 more lbs)
CYA - 40
Copper .62
Iron - .4

I am going to add 4 inches of well water tonite and I still have the brown stuff on the bottom of the pool that needs to be vac. The pool is cloudy.
I put in metal out today. I know I will have more brown stuff in the morning. The pool does look a lot better and the DE is clogging a lot less.
Thanks for any suggestions. Should I post on metals forum?
