I have a 34,000+ gallon gunite pool with salt cell.

Was on an extended vacation. Returned home and my pool was dark green. My control box said salt was low and chlorinator was off. I new it rained non-stop while I was gone so I went ahead and added salt. Next day, control box still says salt too low so I tested the salt myself. Showed 3800 ppm.

I removed the salt cell and cleaned it and reinstalled it. The control box now says my salt is 1600ppm and is too low for the cell to come on. At this point I assume there is a problem with the cell. For now, I want to clean up the pool without the salt cell issue being resolved. I will tackle that once the water is cleaned up.

I have a cartridge filter system with 4 long tube filters. I removed them and cleaned them.

Next I took some water to the local pool shop for testing.

Pool store water test results 2/27/2012:
CYA 0 ppm
Chlorine 0.1 ppm
Combined Chlorine 0 ppm
pH 8.0
Hardness 150 ppm
Phosphate 100 ppb
Copper 0 ppm
Iron 0 ppm
TDS 0 ppm

They told me to put CYA in the pool, 13 pounds and 1/2 gallon of muratic acid. I screwed up and added the CYA to my skimmer (as per the containers instructions) only later to find out I should not do this with a cartridge filtration system.

I went ahead and added 4.5 gallons of bleach to attempt to slow down the algae. Also began running pool filter 24/7.

A couple of days later I added another 4.5 gallons of bleach.

Back to the pool store to test the water.

Pool store water test results 3/6/2012:
CYA 15 ppm
Chlorine 2.1 ppm
Combined Chlorine 0 ppm
pH 7.6
Hardness 180 ppm
Copper 0 ppm
Iron 0 ppm
TDS 0 ppm

Water is still quite green, however I can now see the bottom of the pool in the shallow end, but not yet the deep end.

Here is the advice from my pool store:
Sprinkle in 2 pounds of Mustard Eliminator directly into the pool.
Shock pool with 3 pounds shock
run pump 24/7
Next day shock with 3 pounds shock again
run pump 24/7
next day shock with 3 pound shock again
run pump 24/7
add 6 oz concentrated clarifier
Bring water back in for testing again.

I have read on this site that it could take 80-100 gallons of chlorine to clean up my pool. This is more expensive than the treatment listed above which is about $75. However, still looking for advice before I pull the trigger on any kind of treatment.

Also, through all of this I am running my tiger shark pool cleaner to keep the solids off the bottom of the pool etc.

Thanks in advance for any advice you guys can give.
