My pool water turn green after adding bleach then turns back cloudy blue, what's wrong?

Question

For about 2 weeks now I have been trying to get rid of a bad case of algea. After alot of hard work I did manage to get the water to a cloudy blue color instead of green but that is where I am stuck at. I can't seem to get the water to that pretty crystal clear state. So for several days now I noticed that when I add a gallon of bleach, my water turns green and stays that way for about 5 or 6 hours then it goes back to the cloudy blue. I also added more algeacide this morning. Does this mean I still have algea in the pool ?

My pool holds 7633 gallons of water and my readings this morning before adding the bleach were:

total hardness-200 Free Chlorine -0 ( has been there for days no matter how much bleach I add)

pH -7.5 Total Alkalinity - 180 and Cyanuric Acid is somewhere between 0 and 29, on the test strip it is a yellowish orange color that is not on the back of the hth 6-way test strip box.

Thanks in advance.

Answer 1

That's a filter issue for sure

Answer 2

I don't think you are suppose to use bleach in the pool.  It isn't quite the same as pool chlorine.

Best thing to do is to get a water sample and take it to a pool shop.  They can test the water and recommend what needs put in it.  They do it for free.

Answer 3

Cloudy pools are usually a result of low Ph levels.  Clean the filter, put in shock and add PH up.  Chlorine alone will not clear it.  As for the algea.. there is a chemical for that too.  Good luck

Answer 4

First, get yourself a good test kit. The test strips are not accurate. Also, bleach is exactly the same as pool chlorine and is frequently less expensive. You do need to add lots of it. With a Cyanuric Acid level of under 29, you will lose nearly all of your bleach after a few hours of sun. Plan on testing and adding bleach several times a day to keep your chlorine level up high enough to kill the algae.

Answer 5

You may have to empty the water and have someone scrub the bottom of the pool
