The idea was perhaps to open the capsules and put their contents in a bag of media, like the one used for Purigen, for example, put in the sump for a few hours and check what happens ...
Yes, the marine context may make everything different, but since this material is derived from an organic material of marine beings, it is at least to be expected that it will not be toxic nor will it alter the parameters of water very much ... it may be worth trying , IMO, and if you have any good results, it can be a good acquisition for the hobby.I've not seen anyone try it. It might well be worth testing, but this article isn't very convincing that it would necessarily work.
The main tests (not the kinetic tests in well water) were done with only aluminum sulfate in the water (no other ions competing for binding sites), and aluminum will be in a different form with a different charge in seawater (AL(OH)4- and Al(OH)3) than it was in these studies (Al+++, AL(OH)2+, Al(OH)++).

It's a fine product, but as I said, binding aluminum is tricky since it is not even clear that aluminum in reef tanks is present as individual ions that can be bound, or as some sort of particulate that is unlikely to be readily bound.
If its particulate wouldnt a micron sock or skimmer remove it?
Either way, the product is on its way to me.
No, it may be much finer than a sock opening size.
