ONYX SAND
Kg.7
Onyx sand™ is a special clay, porous and jagged, excellent as a natural substrate for the planted aquarium
It can also be used as a normal substrate in any freshwater aquarium
Being rich in carbonates, Onyx provides advantages for any type of plant that can feed on bicarbonates (lawn plants)
Onyx sand™ can be used with other substrates, but is more effective alone. No integrations are necessary as in the case of laterite or other competing products
Onyx sand™ never needs to be replaced, it remains effective for the entire life of the aquarium, it is not chemically treated and does not alter the pH of the water
Although it is pre-washed, it is preferable to rinse it before using it to eliminate residues
An initial opalescence is normal and will disappear quickly (2-12 hours)
