First thing to deal with is the CYA! My suggestion is to drain and refill to get the level down to about 50 ppm. That would mean draining about 75% of the water. Is your pool AG or IG? Draining vinyl pools is not my area of expertise but I know it can cause liner damage if you drain much below the skimmer without a liner vacumn going. You can drain a foot of water and replace it and repeat this process until about 3/4 the depth of your deepest point has been reached. For example, If the deepest point in your pool is 4 feet then you can drain and refill a foot of water 3 times. This will be the same as draining 3 feet all at once and will replace about 75% of the water in your pool. Once that is done retest and post your numbers.

If you really don't want to drain and don't mind running your FC at at least 8 ppm and shocking to 25 ppm (which can be iffy with a liner) then I would get the FC level up to 25 ppm and KEEP IT THERE until the pool starts to clear and your FC level is holding overnight with no CC. Then let the level drop to between 8 and 15 ppm FC and keep it there for normal operation.
Your iron level of .2 ppm is strange since you just used a sequestering agent. It might mean that you have not put enough in the water to deal with all of the metals. I would have the water retested for metals and if there are any present I would treat with a sequstering agent BEFORE bringing up the chlorine to avoind possible staining.
BTW, there are a lot of seqesterants besides Bioguards Metal Magnet. Jack's Magic is a good line and Proteams Metal Magic works well also. They are, for the most part, all the same....phosphonic acid derivatives. This is a good place to comparison shop and to READ THE LABEL directions since most of them have special requirements for such things as pH and chllorine levels when you add them.

Hope this has been helpful
