Struggling to get water clear

[Mm_putnam]

Getting the dichlorvos from Sam's today. What is my target FC? And can anyone suggest a starting quantity? Assuming it takes some time between application and testing I don't want to overdue it or waste time but underdoing.
I checked FC today and it's showing nothing - added powder and no red at all. My readings from two days ago were as posted earlier.
On a positive note we can officially see the bottom now. So it's coming around but very slowly. If i can make the time this wknd I'll tackle opening, cleaning, and re-charging the DE in the filter.

50k gallons => 10 ppm dose of dichlor => 8 - 9 lbs

1. Add a 10# (12 measuring cups -- not the little scoop in the bucked) dose to start. Broadcast it over the pool, but check the wind, and don't let the dust blow back on you, and especially, do not breath the dust!

2. Dichlor has little initial effect on the pH, but will lower it a lot as it breaks down. With no skimmer, I'm not sure how best to add it, but you should add a box of borax with every 10# of dichlor. On a pool that large, you'll need a lot of borax, so clean out the Walmart shelves when you find some there. If you can't get borax, you can use 1/2 box of washing soda for every box of borax . . . but you'll end up with higher alkalinity, and that *may* be an issue.

I put the photos on Picasa, but I'm not linking them in. You have a Hayward CL200 tab feeder -- which restricts flow tremendously and a PacFab (Pentair) Challenger II pump. Otherwise, the labels weren't readable. The motor label was very clear, but most of the data needed was below the camera. The Challenger labels appear to be readable, but the photo was out of focus.

We found Borax at local grocery so I'm good there.

On the tab feeder, would it be best to remove it to improve flow?

I'm not sure. You may not WANT more flow; your filter performance will be better if the flow is under 50 GPM, but with a 2" multiport, and a PacFab Challenger, you may run 80 GPM if you take the feeder out.

Take some better pictures, so the whole motor and pump labels are legible, and also take some overall pictures of your equipment layout. You may need to replace the impeller on the pump -- which will reduce flow AND electrical usage
