Very cloudy water

[waterbear]

How high was your calcium when you added the sequesterant? Is it the same reading now or has it dropped?

here are my numbers:



CYA=39
tot chlrine=0.4
free chlorine=0
ph=7.7
tot alk=83
tot hardness=292

Have you attempted vacuuming to waste ?

Marie (mbar) I believe is on vacation...she would probably let you know if the sediment is a residual from the ascorbic powder...

You might want to read through my 2006 post, sounds like you're having the same issue that I did.

Yes, it is from the saturation of the water that it gets cloudy, it precipitates calcium and some other stuff in the water that the water can't hold anymore. You probably had some of your calcium and alkalinity fall out, if you compare former chemistry you had. It can take time for it to dissipate. You can put a coffee filter in your basket of the skimmer to catch some of the really fine particles. You can also use a floc, if it really bothers you - follow the directions on the bottle, then vacuum to waste. You can swim - it is only cloudy from too much saturation, it is clean water!

Sorry I didn't answer, Finally got on the computer! The vacation is great!

I did use PowerFloc by Biogaurd. After vacuuming a lot of water and refilling, I must say that it looks pretty good. It is still cloudy but very much better. My kids were in the pool today.

The stains have not returned, and it has been 7 days since I started the Vit C treatment. I also got a good kit K-2006 and here are my numbers:

FC=2ppm
CC=3.5
ph=7.0 (added 4# sod carb to bring to 7.4)
alk=100
CH=340

CYA: did not test because water is still cloudy.

My questions are:

When can I Super Chlorinate to rid the CC?
When will the cloudy water become brilliant.
Can I still use Calcium hypochlorite. I have been using straight bleach lately but I find the granular easier to use and takes less space. Also to superchlorinate would require 5 gallons in my 15k ig vinyl pool. I just want to be careful of not increasing my CH.

Thanks for all the help. I am seeing the light at the end of the tunnel.

You should leave your ph low. Do not add any chlorine till you are sure that your ph is not above 7.2. It is better at 7.0 while shocking after dealing with stains. Do not use any more calhypo - I find that it really adds to staining. Just use plain bleach. Start with 2 gallons, wait a little to see if stains start. If they do add more sequestering agent. If not add the other 3 gallons. Keep it there until the chlorine holds overnight. Remember, high ph along with high chlorine will make any metals that are not sequestered fall out of solution. Calcium is a metal - that's why I think the calhypo adds to stains. The calcium will cloud water too. I think your best bet is to lay off the calhypo - I know it is easier to deal with, but once you get your water where you want it, the bleach will not be hard to use, as you won't have to use very much every week if your cya is between 30 - 50. It would be a good idea to know what your cya is, this way you are sure of the amount of chlorine you need. Hope this helps, let me know if you have any other questions
