I have a gunite 28,000 gallon pool which is completely cloudy after being shocked and I cannot see the bottom of the shallow end. All of the algae is gone (well theres no green in the pool whatsoever. Currently working on getting rid of any residual dead algae.)

I know this can be caused by either all the dead algae, which I'm working on right now.

I also know this could be from high calcium hardness... but I dont know what it should be.

I did the chemistry test with a Leslies drop based test (25ml of pool water, add 10 drops clear and mix, ad 5 blue and it turns red, add single drops of something else until it turns blue.) It took 12 drops for it to turn blue, and it says to multiply that by 4 = 48.

SO thats my calcium hardness supposedly, but I don't know if its normal or not, and an hour searching the forums resulted in no definite answer for me

Also, what else could the cloudiness be. I've backwashed, cleaned the filter manually, and have been running my filter for almost 5 days straight.

I suspect its dead algae, and will know more in the morning I suppose. I put a nylon stocking over my skimmer basket and it got caked with some slimy whitish-brown stuff every few hours. The calcium test was just to see.
