Yes, but as you probably know, alum is 'twitchy' -- you have to get your CA high and your pH low (by pool standards) for optimal results with most particles. Polyaluminum chloride is more effective and less twitchy. I'd found some on Amazon, but it's not available, but I did some more looking and found that GLB Drop-n-Vac is an alum and PAC blend. You may want to try that:

I would recommend a jar test, first.

I'm trying to find some plain, high concentration PAC, but I'm not having a lot of luck.
