Biogravel (1.5kg)

£23.99



Suitable for freshwater and marine use

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.

Free gel filter starter balls are shipped with every order - simply add them in with the media in your filter and they will slowly dissolve, helping to seed the filter naturally and very effectively with live bacteria.

Reviewer: John Heron Gateshead   5 Stars
Bought 1.5kg of filter gravel after watching pondgurus youtube channel (video about the juwel internal filter aswell as others). He very kindly put some mesh bags and bacteria balls into the package aswell. Delivery was very fast. I changed the filter sponge set up and placed the mesh bags full of biogravel and now i have 0 nitrite, ammonia and nitrates. It goes to show that the stock sponges you get are next to useless, apart from taking out the bits that float in the water. With the sponges i always had medium nitrites, ammonia and nitrates but now its 0....very happy and even more importantly my fish are healthier, happier and show their true colours and personalities. Many thanks, will defo spread the word on this. Words cannot explain how happy i am now.
