Biogravel Marine is an entirely new concept for filtration and is essentially a porous gravel made from sintered glass which has a wide range of applications. The latest development from Biohome, Biogravel Marine is the ideal substrate for your tanks. It will not increase pH, supports growth of zooplankton and is the perfect playground for shrimp. Having a porosity of approx. 42% it performs at a similar level to the Biohome Standard and Plus with the added benefit of being small enough to be used in very small situations.
The most obvious place for Biogravel is as a substrate in aquariums which have an under gravel system where it acts as not only a substrate but also an effective filter media too.
Many internal and HOB filters will have very limited provision for biological media so Biogravel is perfect to boost performance by offering an efficient media for bacterial action to occur.
It is most suitable as a media for under gravel filter, internal filters, HOB filters and DIY filters made from ornaments.
The Biogravel is easily cleaned using gravel cleaner (if used as substrate) or by vigorous agitation in water drained off during tank maintenance.
This media is sold by the kilogram. 1 kilogram of media is approximately equal to 0.9 cubic litres.
For best nitrate reduction use approx. 1.5kg - 2kg per 100 litres marine aquarium water.
