Joe, we are assuming you have a green mess on your hands correct? If you are preparing to start a SLAM Process, don't try to double any dosage amounts. Follow the FC/CYA Levels to find your applicable FC (SLAM) level based on your current CYA. For example, if your CYA is 30, then your FC (SLAM) level would be 12.
If you have any other questions about the SLAM Process or how to get started, let us know.

You're going to have a battle on your hands. No matter how bad it is, we've seen way worse, so there is that if it helps. 
Do you have a good drain path and cheap fill water ? With vinyl you can drain down to a foot in the shallow end (paying attention for shifting at 18 inches just to play it safe).
While the water level is low, it's easier to scoop the crud off the bottom. The crud will eat any FC you add, almost as fast as you add it. It needs to go ASAP.
