Full instructions and gel filter starter balls are included.
Once the media is mature it will reduce ammonia, nitrite and nitrate.
Check the video section on this site for the biorb video.
Foam colour may vary.
This kit comes with 2kg Biogravel, coarse and medium density foams, fine pad and gel filter starter balls.
The gel filter starter balls should be added in with media - most people put them on top of foams then cover with biogravel. They will slowly dissolve and seed the media (biogravel) with beneficial bacteria.
The tank base should ideally be cleaned once a week to remove uneaten fish food and waste - if you use a gravel cleaner it will remove waste from base of tank and upper foam and it will also remove some water from the tank allowing for a partial water change. Even when a full cycle (0 ammonia, 0 nitrite, 0 nitrate) is achieved weekly maintenance is essential to keep the tank clean and healthy.
Use cleaning pads for acrylic (not glass) tanks when cleaning the inside of biorbs to avoid scratching.

After seeing the video for this on youtube i decided to give it a try as it couldn't be any worse than what you get with the biorb anyway. It has not disappointed. The biorb looks more like a proper tank with gravel now and after six months my levels are constantly perfect. The bacteria works better than liquid stuff and sped up my cycle. Also i got rid of the pump that comes with the biorb and got a 240lph pump so its filtering at eight times the volume for my 30l. I also put a layer of filter floss in the bottom of the cartridge as thats the last layer before the water gets filtered back in to the tank. Water is crystal clear and i only clean my filter foams once every three months. Nitrates generally sit between 5-20 ppm depending on when i do a water change. This is all with my tank overstocked with eight neon tetras, 1 lyretail killi and 3 peacock gobys.

Great kit for any Biorb owners!
Instructions simple to follow, water is super clear
Hardly any maintence required, plenty of fine foam left...

Wish I’d found this years ago! Had my biorb 30 for 11 years with mixed success. Turns out worst thing I did was introducing moss balls; spawned everywhere and continuously blocked the filter and media. This kit and video made doing this upgrade very easy. The new gravel looks great and the bacteria starter balls helped to get the cycle going. Enough foam left for complete replacement of the 2 bigger pieces and multiple replacements of the cartridge foam. Thank you.
