Not much info out there on Aqualoon (with a Q), but the Chinese manufacturer lists it as 100% polyethylene http://www.starmatrix.cn/ProductView.asp?ID=302. Doheny's http://www.doheny.com/poolsupplies/Aqualoon-Filter-Balls.html info says "Lowest back wash frequency" so I assume it is cleaned by back flushing, just like a sand bed. You might contact Doheny's or where you bought the Aqualoon for more info.

The answer to this question depends on the specific chemical magic used by your, whatever this stuff is, "agualoon sand alternative"

I am guessing your magic sand is some kind of solid sorbent, and the magic which occurs is some kind of sorption chemistry.

https://en.wikipedia.org/wiki/Sorption

Note that sorption is kind of a huge topic, so more specific information about your sand, eg. what it is made of, what chemicals it removes from the water, etc, that info would be very helpful for to find an answer specific to your thing.

Because sorption is a kind of chemical magic process, an additional magic ritual (involving heat, other chemicals, etc) may be required for to reverse the original magic, to make dirty sorbent clean again.

Because this sounds very vague when described generally, I will give you a more concrete example.

Desiccants are sorbents that can remove water vapor from air, to make humid air into dry air. Silica gel is a cheap and popular example of one of these kind of sorbents. The way it works is, at the microscopic level, it has a huge surface area, and more importantly these microscopic surfaces are (for some reason) attractive to water molecules.

After a quantity of silica gel which has adsorbed all the water it can adsorb, can be regenerated using heat, typically by baking it in an oven at some temperature for some amount of time. The wikipedia article on Silica gel suggests " heating it to 120 °C (250 °F) for 1–2 hours", and of course you chase down the reference for that, or find others by feeding the words "regenerate silica gel" to any search engine.

Anyway, that's the magic ritual required to regenerate silica gel to dryness.

It's maybe kind of weird example to use with words like dirty and clean, because the "dirt" that sticks to silica gel is just pure water. I.e. clean silica gel has surfaces free from water, and dirty, used up, silica gel has its surfaces covered by water, I mean microscopically. Just to naked eye, dry silica gel and wet silica gel look identical, unless it's the kind that magically changes color. In any case the amount of water, there, or not there, is typically large enough you can measure it by weighing (measuring a change in mass).

Other kinds of sorbents require other kinds of magic.

E.g. the ion exchange beads in water softeners are regenerated by soaking in salt water.

E.g. manganese greensand filter media is regenerated by soaking it in a solution of potassium permanganate.

What I'm saying is, this is kind of a wide topic, which is why it would be helpful to know more about the magic specific to your magic sand.

I tried asking Google(r) and Google(r) Images about
"agualoon sand alternative"

but Google thinks I'm spelling it wrong, and it is kind of pointing me in different directions.

A search on the phrase "regenerative sand pool filter" might offer some clues, because, apparently such things exist, i.e. filter media of a kind intended, designed, to be regenerated somehow, but I have only just glanced at the titles that popped up, and I have no idea about the nitty-gritty details of how these things work, or how well they work, and so forth.

By the way, I am assuming your magic sand is using sorption, some kind of chemical magic. If instead your filter is using biological magic,

https://en.wikipedia.org/wiki/Biosand_filter

then the filter media is just a substrate on which to grow microbes as a biofilm. In contrast to chemical magic, you don't ever try to regenerate biological filters, using heat, chemicals, etc, unless you're intentionally trying to kill the community of microbes living there.

I guess that all depends on what you used it for the first time.
