When my spa company did a repair on the spa, they put a little green spongey cylinder in the filter tray that sits in the skimmer compartment (see photo). What is this and is there any reason I shouldn't remove it? Thanks!

Thanks. It's weird that, while it looks like a sponge, it crumbles into tiny pieces if squeezed (or really even if touched). Not how I understood a typical scum ball to work.

How The Pool CuZn & The Spa CuZn Work:


Enjoy a luxurious swimming experience without irritating and potentially harmful chemicals.

With The Spa CuZn, you can forget about all the headaches of storing multiple toxic chemicals in your home, along with the weekly hassle of testing.

The New Spa CuZn Cubes System consists of 1″ cubes of Spa CuZn Media enclosed inside a mesh bag and The Spa CuZn will typically last for 3-5 months.

The Spa CuZn Cubes are flexible and can be squeezed into place, simply squish the mesh bag of Spa CuZn Cubes into the tub’s skimmer basket to install.

A snug fit is best, as it is important that all the water flow through The Spa CuZn Media during the recirculation cycle.

The Spa CuZn’s all natural process, made possible by our unique reticulated KDF media, utilizes catalytic action and redox (reductions/oxidation) principal of dissimilar metals.

When the spa water comes in contact with the reticulated KDF Media Cubes, a reaction takes place that forms copper and zinc hydroxides.

These controlled releases purify the water creating a conditioned, stable environment that prevents scale and bacteria growth.

KDF Media has been tested by the national science foundation and received NSF certification standards 42 and 61.

CuZn’s reticulated KDF is currently used in commercial and residential applications, including the filtration of drinking water.

Unlike other chlorine alternatives, The Spa CuZn will never cause staining.

The Spa CuZn should be used with a Potassium Monopersulfate mini shock, we highly recommend only MPS Shock be used for best results.

A mini shock is a 50 percent dosage of what the manufacturer of the Potassium Monopersulfate recommends, an MPS shock is recommended on a weekly basis and immediately after bathing in the tub when using The Spa CuZn System.

When using chlorine based shock, remove the Spa CuZn for a 12 to 24 hour period to let the chlorine dissipate.

The Spa CuZn is not compatible with Biguanide Chemical Treatment Systems.

Probably a ceramic or silicate Reticulated Foam Filter with copper, silver and/or zinc embedded in the foam.

ATS is a ceramic, cationic ion-exchanger with high specicity for lead and other heavy metals. ATS is not eected by
competing ions like calcium and magnesium and will not leach either organic or inorganic residues. ATS has an amorphous
crystalline structure and a bulk density of ~68lbs/Cu.Ft.

SZT is an inorganic silicate compound with a negative internal polarity. SZT has a denite crystalline lattice structure of
exceptional stability and a bulk density of ~30lbs/Cu.Ft. The negative polarity gives SZT an anity for ammonium, lead, mercury,
cadmium and other dissolved metals.

Yes, this seems like a good call. I'm presuming I can just get rid of this, yes? I've never seen anything like this called out as part of the TFP approach.
