This is the popular Biogravel ready bagged in a small mesh bag. Each bag contains a minimum of 250g.
Please note: In response to customer feedback regarding the packed out 300g mesh bags we used to sell we have reduced the amount of media in each bag (and reduced price accordingly). They now fit into filters much better.

Suitable as a shrimp and plant substrate, media for under gravel filter, internal filters, HOB filters, small canister filters and DIY filters made from ornaments.
Biogravel is an entirely new concept for filtration and is essentially a gravel made from sintered glass which has a wide range of applications. The latest development from Biohome, Biogravel 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 Biohome Plus with the added benefit of being small enough to be used in very restricted spaces.

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.

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. 1kg per 100 litres aquarium water for a normally stocked tank or 1.5kg - 2kg per 100 litres for a heavily stocked tank.

As all Biohome media is inert it allows you to raise or lower the pH to suit certain fish species without having a buffering effect.
