BioGravel media is the ideal substrate for your tanks. 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, internal, HOB and canister filters.

BioGravel media is also an ideal filter media. The dense BioGravel allows you to pack more media into a given space than any other variety. All of the GreatWave Endless River Koi Pond Filters are now filled with BioGravel. To see how much your filter requires return to the Home page and click on the link at the top, “How Much Do I Need“.

BioGravel is a small, round media ranging in size from 1/8″-1/4″ in diameter. Similar in appearance to BioMotion, it is much denser. 1 kg occupies about 56 cu in.

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 TM 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 TM 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.

    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.

      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

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

    • newfish

      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.

    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

      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

    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.

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

    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

      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,

    I purchased the kit for the BiOrb 30L and I have to say this stuff is amazing. I did a fish less cycle and once the tank was cycled I added fish. I do weekly 10% water changes but that’s about it. My water perimeters are always zero, with the exception of PH of course. It’s amazing, So much so that I started another BiOrb for my daughter. Normally I would not concerned using a tank like the BiOrb. The 30L was giving to me as a gift so I did some research on how to make it better. The Biohome Gravel actually make this a safe tank to use. In the 30L I have a Betta and three Cory’s. My daughters tank is only 15L so it only has a Betta.

    • Don Chamberlain

      Thanks for the great feedback. I’ve sold quite a bit of BioGravel for BiOrbs, but this is the first feedback I’ve received. It’s great to hear how well it works. I was concerned how well it could be maintained, but it sounds like that is not really a problem.
      Happy Fish Keeping,

    I am using this in a biorb 30L. I did the foam filters as seen in the upgrade video that reccomended this. It has worked beautifully. I now trust it so much I am buying more for a small back up hospital tank.

    • Don Chamberlain

      Thanks for the great feedback. I’ve often wondered how the BiOrb upgrade worked. I’m glad to hear it’s working well for you.

    I purchased this for my 60L Biorb. The only thing that is not in the perfect range is Ammonia, I am sure this is because I overstocked my tank, and then too many fry were born and thriving. My plants are doing excellent, everything is growing. I have a couple of Ghost Shrimp, and can not believe how large they have grown. Can’t say enough about the BioGravel.
    I ordered a second 2 kg from another supplier at a cheaper price, thinking it was a good deal, but their 2kg was a much smaller amount than the same order from you. I will only purchase from you from now on. Planning on getting a larger, 55 gallon, tank next and will want this as substrate in it also. Great product.

    • Don Chamberlain

      Glad to hear the BioGravel is working so well for you. The fact your ammonia is not zero concerns me a bit. I hope it is very low. It is probably explained by the fact you’ve had a spawning and the filtration in a BiOrb is not very efficient even with Biohome. I’m glad to hear you’re planning on a bigger tank. That should work a lot better if you get a large enough filter.

      Remember you need 1.5-2 kgs of Biohome per 26 gallons so that would require a filter that will hold about 4 kgs. The BioGravel substrate will help some, but since there is not a steady flow through it, I wouldn’t count that.

      The other sellers of Biohome in the US sell by the pound and a pound is less than half a kilogram so if you got 2 pounds it would be quite a bit less than the 2 kilograms you got from us. Continued success with your fish and shrimp, and…

      Happy Fish Keeping,

    Don, I finally got the Ammonia down by doing large water changes and vacuuming. Since then I have added an Aqueon Quietflow internal power filter. It fits nicely in to the Biorb. I turned the outlet to the side pointing directly at the heater, it is pretty powerful but since it is directional, doing this lets the fish still swim around in either direction without swimming against the flow. I hope by adding this and continuing water changes I will be able to keep the Ammonia down. Time will tell. Thanks for a great product.

    • Don Chamberlain

      Glad to hear you got your BiOrb working well. Great idea to enhance the filtration.
      Happy Fish Keeping,
