The trick to staying on top of your water starts with frequent testing. You'll need to get a full set of test numbers to see where your at. In those numbers be sure to include your CYA (stabilizer) levels.

If your chlorine is getting used up quickly you may be on the verge of an algae bloom or your CYA levels may be low. There could be other possibilities for cloudy water but it's probably better to wait until you post that full set of test results. Right now...check your pool chlorine often and ensure that your keeping chlorine in there.

What type of algaecide did you use? what was the active ingredient?

What type of shock do you use?

How long have you had the pool?

thanks,
dan

A full set of test numbers would help us be able to tell what is happening, without that it is just random guesses.

My random guess is that your CYA level has gotten quite high and the chlorine is no longer being effective so you are starting to get algae, but without more information I can't really say.

Your FC level is probably a bit low given your CYA level. If you have 50 ppm borates or a SWG, FC of 2 might be alright, but otherwise you should be at least 3 or 4 and preferably 5 or 6.

Cal-hypo can sometimes cause some calcium cloudiness. Lowering the PH slightly or waiting a few days usually clears that up, though how likely it is to cause cloudiness and how easy it is to clear both depend on your TA and CH levels, which you din't list.
