Thanks for sharing!I dumped a 3 gallon pail of chlorine in about 4 days ago, that is what switched it from green to cloudy, and also what I called "shocked".
There is about 3-4" of visibility in there, pretty bad..
I went in it yesterday to have a better look/feel, there is no slime. Besides the color you would never know anything was wrong..

As "chem geek" said you need to get a decent test kit (K2006c or TF100) because you need to test regularly
You have an algae bloom and need to Slam (Shock Level and Maintain) with relation to your Chlorine / CYA Chart and your recommended Pool Levels
Keep brushing, filtering and backwashing

Your figures are way off but you haven't included CYA(Cyanuric acid)
Also what is your pool construction
It seems you have an algae bloom

Above ground suggests vinyl liner pool. Is the water grey/blue from dead algae? What filter & pump setup have you and has the pool got a surface skimmer or just a pipe through the wall to the pump?

My pool (above ground 12' x 3' deep) water is cloudy and I can't seem to fix it. The ph level is in the normal range. Algae became a problem when we were away so I added a gallon of standard bleach than lots of flocculent. Nothing. Does anybody have any advice?

Good to hear that others have this problem too. If there is any solution... please let me know.

Hi Nicky a bit more information on your pool, filtration and pump/plumbing would help along with latest water test results.
You need to shock your pool (SLAM) as Dennis says. Shock is a process not a product, It's raising the free chlorine level high enough and holding that level with regular additions of chlorine until everything is oxidised out of the water. Your filtration can only remove what it can and that's the difference between great filtration and poor, poor will get there it just takes longer.
