Cellulose to remove metal?

I've seen it posted many times that you can only suspend the metal in the water, but not remove it. Omni, Bioguard and Jack's Magic all have filter aids that claim to "help" remove metals.

The wife and kids are going to Cedar Pointe this coming week and I want to work on the mild to moderate staining on my fiberglass pool while they're gone.

Should I try any of these products after adding the sequestor or should I not spend the money? If I can remove some of the metal I'm assuming I can reduce the amount of sequestor needed in the pool.
