I would say no, absolutely not.
First off, you don't need anything like that. It binds to what is in the water and carries it to the bottom for removal, from what I can read. If you maintain your fishtank with any energy at all, there's nothing to bind to that's a worry.

In a pond where sun feeds algae, those are popular gimmick products to make up for poor location of the pond, etc.

There are versions of that product sold for aquariums, but they are a waste of money.
