This is a very long story or chain of events - i have a 18k gallon, inground. liner pool, Goldline Aqua Cell salt generator, haward 1.5 hp pump, 300lb sand filter. I run the filter all year long so never have 'Opening" issues. This year i didn't switch from night filtering to day filtering soon enough, and became very slighlty tinged with algae. I switched over to day filtering and instead of pouring regular algeacide in the pool, inadvertently dumped a whole bottle of copper algeacide in, which of course caused formerly non-existent metal levels to sky rocket. The battle began trying to clean out the metal. After 15 bottles of a metal free product i figured out it wasn't going to do the trick. On the advice of a pool store, I dumped 20 lbs of Alum into the pool and haven't been able to see the 3rd step since. The alum didn't drop after 4 days and i was instructed to raise the PH levels to at least 7.8, turn off the filter and give it 4 more days to drop. I had to be at 0 chlorine to use the Alum so the salt system was turned off. The alum never dropped, but i have vaccummed to waste, lowered the pool water to 6 inches below the skimmer line and refilled. I can't see to the bottom of the skimmer basket it's so cloudy - a milky blue. I have added fiber clear to the sand filter (thru the skimmer basket) and for the first 2 days have had to back wash within four hours after adding it. After one full bag and 6 days of adding it, the pressure is no longer rising. I've replaced the sand in the sand filter after vacuuming out what i could of the alum. I've been working on water balancing for the last 2 days and my current readings are:
FC - 1
TC - 1
PH - 7.6
TA - 120
CYA - 5-10 (have a nylon filled with CYA hanging in front of my return as i type)
Hardness - 110
TDS - 3300
Salt - 2400 - The Aqua Cell reads 2700 and says it's generating
Phosphates - 0

After reading your forum sent my husband to the store for 6 gallons of 6% bleach.

I had a bad test kit that was reading my chlorine levels at over 3 - the above are pool store results from today. Also of note is I can smell chlorine. With the salt system, i've never smelled chlorine, so I dropped the Chlorine generator to 30. It typically runs on 50.

How can i fix this horrible mess that's been created? Is it possible an agae bloom is creating this non-see-thru water - considering no chlorine was added to the pool for 2 full weeks at temperatures of 70-83 degrees. Will bleach help? Please help me. Thanks so much for taking the time to read this - i know it was a long one.
