green water

[mrszaff]

Hi, I opened the pool 2 days ago, it was perfectly clear, I added 4 gallons of 6 percent bleach and ran the filter, the next day it was bright green.
I back washed and added 8 more gallons. today it is still green but you can see the bottom, so I had it tested but Leslies told me the shock level was too high to do a reading. ?? and not to add anything until it comes down. It has been raining as well.
I vacuumed and back washed again. just now. should I let it be or add more bleach until it clears?
I will look for my taylor kit and will post numbers tomorrow.
Thanks!

Is it green and cloudy or green and clear? What is the source of your fill water. If you shock a clear pool and it turns green, it leads us to believe it could be a metals issue.

green and clear I think. when i back washed it a lot of green came out. we had a metal issue a few years ago, so maybe I should put some metal free in it? i didn't have to put much water in it this year, 16 x 32 vinyl in ground, city water

Not metal free - it's useless and incompatible with chlorine, if you have the 'new' citric acid metal free.

+ Run your filter CONTINUOUSLY; clean as needed; tell us what color the dirt or backwash is.
+ Don't run your chlorine higher than needed right now.
+ Get a local OTO kit (HTH 6 way at some Walmarts is a GREAT deal, and compatible with the Taylor K2006) and tell us what you have.
+ Locate your eyeballs so that water is NOT directed against a pool surface.
+ Notice and report the color of any sediment that appears on the bottom.
+ Keep your pH ABOVE 6.8 but BELOW 7.4
+ Get the K-2006 ASAP.

*IF* it is metals, a liquid product like Metal Magnet can help prevent staining . . . temporarily. But, it's not really compatible with chlorine levels above 5.0

The pool is not green today but the liner is brown so I put a vitiman c tablet in to test a spot and it cleared. Just bought 2 lbs of concentrated ascorbic acid and sprinkled it around and the liner is beautiful wherever it landed. I am hoping it will get everywhere by running the filter all night. We went through this a few summers ago. I'm so mad its back!

Ok.

You've got the iron BACK in your pool water, but you do NOT have it OUT of your pool. Also, ascorbic acid and chlorine are incompatible. Go TONIGHT and get some polyquat (www.poolsolutions.com/polyquat.html) and use it -- it's fairly compatible with BOTH ascorbic acid and chlorine.

Then, you need to find a LIQUID metal stain and scale product -- Metal Magnet or the Jacks Magic Purple, Blue or Pink Stuff all have the ingredient you want, HEDP. Once you have some, use it.

THEN, you can safely begin re-chlorinating your pool without immediate danger of re-depositing all the stains.

Next, you'll need a K-2006 test kit (see test kit page in my signature) AND you need to read through this thread:

to get an idea of what your options are.

Thank You so much! I just tried to get a reading but the FC must be extremely high, the water turns red not pink and I gave up after 100 drops, I will try again later on today.

The water is still clear BUT the stains are still visible wherever I couldn't reach with the ascorbic acid, will this eventually clear up I am ready to go buy more as I am under pressure to make it look good by Sunday for a party.

I am ordering more for the future from amazon thank you for your link! THe metal free was put in the pool without my knowledge this morning , when my husband saw the stains still in the pool today, Its not the citric acid new one, Ive used it before. Hope it doesnt make it worse.

SO moving forward...
Today I will get Polyquot and add it, Is this to prevent algae growth when the cl drops?
I will look for liquid metal stain as well for immdiate use

I am ordering the kemtek from amazon and ascorbic acid and culator after reading your link.
To get the pool looking better until all this arrives, I guess I will just add the ascorbic acid again, hoping it will eventually get to the center of the deep end, I do not anticipate any swimmers since the water is so cold.
but I need it to look less offensive by sunday....
Am I on the right track now?

THANK YOU SO MUCH!

Whoa! If your chlorine level is high, do NOT use the polyquat. It's not compatible with chlorine that high! If you've already purchased it fine; keep it for a future need.

Also, don't put phosphonate in (HEDP); again it's not compatible with very high levels of chlorine.

Please post your POOL info -- surface type, gallons , pump/filter make/model, etc. -- in your signature (link in my blue signature block) AND please report a complete K-2006 test set. I particularly need to know what your CYA level is. (You don't have to repeat tests you've done recently -- just tell me what your current levels are)

Do be SURE to keep your pump running -- high chlorine will break down whatever you've used to lift the metals, but if it can break down in the filter, then the metals will end up there, and you can remove some from your pool when you clean the filter.

As far as I know, the CuLator *is* compatible with high chlorine, but I'll call this AM and ask.

However, NONE of these things will arrive in time for this weekend. If you have access to local citric acid -- I'm not clear on what you have been using; if you post EXACT product and brand name, and approximate product age, I should be able to tell -- and IF the citric acid lifts the stains, then with your very high chlorine, you can add it, put the metals in the water, let the chlorine break it down and *hopefully* it will be filtered out

BTW, if you are not doing so, with HIGH chlorine, be sure to use the SMALL sample size on the K-2006. If you fill to the 10ml line, each drop is 0.5 ppm chlorine, rather than 0.2

hm-mh.

Retest that CYA, using a 50:50 pool water / tap water sample, and then multiplying by 2.
