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:
