EHEIM SUBSTRATpro+ O2xygen 2Л. 2512101

Biological filtration — providing numerous “biological beds” for colonies of bacteria that break down waste, ammonia, nitrites and other organic/inorganic substances. Enhanced oxygen regime — “activated oxygen” improves water oxygenation, which supports the health of fish, plants and bacteria. Faster detoxification and water purity — contaminants (organic residues, ammonia, etc.) are broken down faster and more effectively, resulting in cleaner and more stable water. Durability and sustainability — the material is very strong, does not degrade, does not disintegrate and can be used repeatedly. Does not affect water chemistry — pH-neutrality and inertness, important for sensitive aquarium systems. What to watch out for / limitations This is not decorative sand or gravel for the bottom — it is not intended as a substrate for planting plants or for “soil” in the aquarium, but only for filtration in filters. When cleaning — the material must be rinsed carefully with aquarium water (not with chlorinated tap water) so as not to destroy beneficial bacteria. It does not “decorate” the reservoir — since it is a ceramic medium, it does not give a natural look to the bottom (for this, sand, gravel or decorative substrate are used). 🎯 Who is it suitable for For aquarists who want effective biological filtration — especially useful in busy aquariums: many fish, plants, organic loads. For people who prefer a durable and long-lasting filter medium that does not have to be changed often. For aquariums — both with fresh and salt water.
