So I am in the process of SLAM'ing our pool. IN 48 hours I have used about 15gallons of bleach. After 3-4 hours the pool chlorine (which is clear, blue, can easily see to the bottom, just was getting algae on the walls and vacuum) goes from 24 to 12-15. Is it normal to go through this much bleach, esp if the algae is not that bad (as in clear blue pool)? Is adding bleach 3-4 times a day not enough? Could it be the temp or constant running of the pump that is making it eat the chlorine this fast (105 degrees out these days)? Or is this just how it goes when SLAM'ing?
Currently SLAM'ing and eating bleach like mad

Take a few pictures for us.
Your goal is to keep it at SLAM level and not let it drop to 1/2 SLAM level.
Your FC is fighting the good fight, keep the supply line open.

From 10pm to 7 am it goes down by half! I have no intention of getting up in the middle of the night 
! LOL. This is what it looked like when I started. 
! LOL. This is what it looked like when I started. I wonder if it is even getting up to 24. I just checked it after 3 hours and it was down to 18.5, that is the lowest reduction I have had so far. Just added another jug of bleach per Pool Math and we will see what it is in the am...

It's 6% bleach from Wal Mart.
From last night to this am, the FC went from 19 to 18.5 and the CC is .5 so I think we are finally there! I did go through 25 bottles of bleach in 3 days, so that was fun!

Next time, FWIW some Walmarts have pool chlorine that is 10% for around $3.65. Leslie's here in Houston has 12.5% for $4, a slightly better unit cost than Walmart, but if Walmart is closer to you...
I will check out the higher concentration bleach at Leslie's (which is actually closer to me that WM) at $4. Bleach at 6% is $2.67 or so.
