I have looked at those 2.
The fish protection dosator
Protects the gills, skin and fins of the fish through natural plant extracts and indispensable vitamins which the fish are used in their natural biotope.
Functions as a natural lining that protects the fish from the agents that cause disease, and has a lasting effect.
This sounds suspiciously like aloe vera. Even if it isn't I wouldn't use it. Fish don't need help to have a slime coat, they do it by themselves. A lot of these 'natural' things that are claimed to stimulate the slime coat also coat the gills. I wouldn't use it.
The Water Clear and Protection cartridge - they don't say what's in it, only that it is chemical filtration. The fact that they say to remove it when adding medication to the tank means that it contains carbon or zeolite or a mixture of them. Zeolite has no place in a tank, in my opinion, as it removes ammonia and starves the filter bacteria. Carbon is not needed full time. it's main use is to remove medication after treatment has finished. (If you ever break open one of these, if it contains black bits, that's carbon; if it contains white bits, that's zeolite)
You can continue using this if you want, but don't bother replacing it. Both carbon and zeolite get full and stop working but are home to the bacteria.
If this was my tank, I would replace both catridges. I would get some sponge, any make, and cut it to the size and shape as the cartridges and use that instead. But only one at a time, with a month between. Replacing the cartridges means throwing away some bacteria as well, so changing one at a time means only a few bacteria are lost each time. Sponges just need to be washed in old water taken out at a water change, they last for years.
