green water that won't go away

[kinneydd]

Just tested the water here are the numbers:
Chlorine 6.0 ppm
Alkalinity 130ppm
PH 6.8, a little low but thats ok while I'm trying to get rid of algae, right?
Calcium 200
Copper 0
Iron 0
CYA 130
The pool still looks green, however like I said in my previous post, it looks better than it did.
I'm surprised that the coper and iron are zero already, does that seem right?
Should I start shocking the pool again?
How much bleach should I use? 14,00 gallons.
Thanks!!

You do have to get your ph up - anything under 7.0 is corosive, and can ruin your liner. I would add a little borax to get it to at least 7 to 7.2. The chlorine will be just as strong there. You can also aerate your water so it will lower the alk and raise the ph. You are testing no metals because all of the metals are binded with the sequestering agent. You can now shock the pool. You have to be consistant, if you let the chlorine level yo yo, it will take much longer to clear the pool. Get the ph up that is the priority.

ok, I have the PH to 7.2, and I added three gallons of bleach , which is what the bleach caluculator said to use. I should be on the right track now.....I will test three times a day and keep the cl at 15 ppm, I hope it clears up soon.

kinneydd,

Is your CYA really 130ppm? If so, you need to get your chlorine up alot higher than 15ppm.

Use the info in this chart to help you figure out what levels of chlorine you need to maintain in your pool based on the amount of CYA (cyanuric acid, also called stabilizer) that you have in your pool. (FC = free chlorine)

Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . .8 ppm . . . . . 15 ppm . . .. 25 ppm

Good luck.

oops, no that was a type-o, trying to type to quick, it is 30.

Thanks

The algae is diffidently stirred up, I have green bubbles floating on the top of the water and the skimmer is collecting alot of algae. The algae turns white when it is killed, is that correct? Since it is still green should I add more bleach? I have been testing the water and I still have the cl up to 15ppm, (I have added bleach to keep it there). How long should it take to kill, if I don't let the numbres drop any?

[aylad]

Yes, it should turn white when it's dead. If it's still green, keep adding bleach to stay at your shock number. How long it takes to kill really is variable from pool to pool.....

Still have green water!!!, It has changed some but not enough to get excited about. Cl is being kept at 15ppm, the ph is now high at 8.2 ppm and the alk is 160. Should I lower the ph and alk? I have been running the pump twenty four seven on high, removing the filter twice a day to clean it, vacuming for several hours a day. It seems that the metals are staying in suspension. Can they fall out with all of this chlorine? Should I add more sequesterant just to be on the safe side? I don't want that problem again. It seems that I should be able to see the bottom of my pool by now but I can't, I hope it clears soon, its actually suppose to be hot this weekend.
