Description

BioGravel media is an ideal substrate, but also a highly efficient filter media. Sintered glass is mixture of silica sand and recycled glass fired at high temperature to form rough, porous glass balls. Nearly inert it should not affect pH significantly, although a large volume may raise the pH temporarily.

It supports growth of zooplankton and is the perfect playground for shrimp. It should also work well in:

  • Small DYI Filters

  • Internal Filters

  • HOB Filters

  • Small Canister Filters

  • BiOrb Upgrades

  • Tank Substrate

BioGravel is a small, round media ranging in size from 1/8″-1/2″ in diameter.  1 kg occupies between 57 and 70 cu in depending on your filter size. To see how much your filter requires click on this link: “How Much Do I Need“.

Complimentary Filter Starter Balls (1/4 bag per kg) are shipped with each order to speed beneficial bacteria growth. The media recovers quickly after the use of medications.

Biohome ® allows both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through it’s unique structure. This allows it to also control nitrates. Check the Rules of Thumb for Nitrate Reduction to estimate how much you’ll need to reduce the nitrates in your pond or tank.

Biohome ® BioGravel Media is a biological filter media and good mechanical filtration must be provided to insure the water passing through it does not contain any debris that might clog it.

Please let us know if you have any questions or comments.

  1. Steve –

    How much Biogravel would I need for my Biorb tube 30L. Has anyone used this in their biorb and if so has it worked well?

    • Don Chamberlain –

      Steve,
      The 30 L model takes 1.5 kgs of BioGravel. We’ve sold quite a bit of BioGravel for this application, but unfortunately I haven’t had any feedback one way or another on how well it works.

      I hope you realize the BiOrb is not the ideal tank and maintenance could be a bit of a problem. The BioGravel has to be a quantum improvement over the paltry filtration provided by the stock BiOrb.

      If you check out our “How Much Do I Need” link on our site and open the BiOrb section you’ll see instructions for the upgrade an links to templates for the Foam Filters.

      Hope this helps. Thanks for your interest, and…

      Happy Fish Keeping,
      Don

    The Biogravel is a great product for my applications; a gutted HOB filter on a 20 gallon tank and a few soda bottle filters in 10 gallon tanks. Of course I use the round foam elements as pre-filters to protect the micro-pores of the media a bit. Not my first time using it. BioHome is good stuff.

    Don and crew did a great job getting it all out to me quickly, well packaged and good price. Too bad my main post office took 2 tries to get it to the correct small town, so it arrived needing a signature while I was at the doctor. Too bad we can’t all work as efficiently as the Post Office and the Fed Gov’t.

      Ross,
      Glad to hear that. We don’t have much experience with BioGravel yet, so glad to hear it’s working well for you.
      Happy Fish Keeping,

    Hello Don,
    What would be the best and most effective method to introduce this product into a tank that’s already planted and established….

    • newfish –

      Steven,
      Good talking with you today. I’m not sure my advice on this subject will be much use. I assumed you’d be able to simply reach in and place the BioGravel by hand. If the plants and other objects in the tank make it difficult or impossible to reach everywhere, I’m thinking you might be able to use a baster or something similar as a sort of funnel that would allow you to distribute the media to the places you want.

      I would think you could hold your finger over the tip of the baster until you got near the area you wanted and then remove it to allow the BioGravel to flow out while you distribute it as you want. You might have to cut the tip of the baster to make it large enough to pass the BioGravel. Probably don’t want to try this with your Wife’s baster.

      You might also be able to use a small net to place the media. If you come up with any good ideas, please let us know so we can pass them on. Thanks for the recent orders. I saw another one just came in. I haven’t seen what it’s for yet. Good luck with all of your experiments, and…Happy Fish Keeping, Don

    Hello,
    I was wondering if this would be a good substrate for a planted tank….

    • newfish –

      Steven,
      I believe it will be. Check out “Betty’s BiUbes” posting on the Customer’s Page to get an idea of what it looks like.
      Happy Fish Keeping,

    I purchased this after seeing a tutorial by the PondGuru. I liked the idea of biomotion but recognize those plastic balls aren’t the best. This things are wonderful, they seem to work very well. They hold up well and are very absorbent (like the biohome ultimate). I added a few of the filter starter balls which works really well because the vibration of the balls break up the filter balls a little more quickly that simply water passing through it. I have had these for about two months now and have no complaints. One thing though, if you follow the tutorial with the DIY shampoo bottle and air pump. is that their vibrations are kind of noisy against the glass. They may be less noisy if they were not suction-cupped but I wouldnt know. Not bothersome to me but I could see how it may bother some people. Highly recommend.

      JB,
      Very interesting. I figured these would be too dense for a moving bed filter, but I guess not. Hope you can post a video sometime. Happy Fish Keeping! Don
