You should definitely backwash you filter at this point.

I've been adding 4 182 oz big bottles of 6% bleach each day and testing over nite Chlorine loss for a week now.No telling How much I added before that plus I keep 4-3' pucks in the floater.At nite its around 22ppm,in the morning about 17ppm(give or take a few).Every nite I loose right at 5ppm and show CC of 1.No change!Water still milky blue bout 6in vis.

Without digging back through the posts, do you know if you have a bunch of leaves, grass, etc. on the bottom of the pool?

No debris in the bottom.I have slid the leaf net all around the pool and even dove to the bottom with a mask.Some white powdery substance in places but thats it.

Could mustard algae be the culprit even after all the chlorine i've added?Could the powdery white substance in places on the bottom be dead/dieing mustard algae?I've had a problem with it in the past but i'm having a hard time believing that there is anything "alive"in this pool.

HOLY @!$&!
Every day I've been putting in 4 182oz bottles of 6% and every evening at dark my chlorine is right at 22ppm.
Today I decided to double it.
Today I put in 8 big bottles of 6%.
Guess what my chlorine was at at dark......GUESS!...........22ppm.........same as usual! :shock:

WHAT DA HE**!

Run a full set of test again and post them. Don't worry about pH as it'll be wrong with a FC of 20+.

When you put the 8 jugs in did you test an hour after to see what your FC & CC were?

HOLD THE FORT! It looks likw it held chlorine over night but now Im out of 0871 reagent and can't get any locally.Not shure what to do in the mean time.I can get it tested at the pool store but can't get a over nite reading.

IF you have an OTO chlorine test you can dilute the sample with chlorine free water and multiply the result. It's not very accurate but it'll keep you at shock level until the reagent arrives.
