=== The product === This is a service kit for a Biorb fish tank that contains a replacement filter cartridge, a cleaning pad and a water treatment sachet. === How to use === Well this is so very simple to change and to use. To change this filter I simply turn my bubble tube and then the filter and bubble tube clicks out of place and if left will float up towards the top of the fish tank. With another twist the filter is removed and the new one can be clicked in to place. There are little indentations that help to ensure that the filter clicks in to place and I can see at a glance that this is back in the right place. When I ...  Read the complete review

If you've read my earlier reviews you will know that I am a proud owner of a 35 litre Bi-Ube tropical fish tank, part of Reef One's Bi-Orb range. These tanks are extremely low maintenance and so much better looking than the old fashioned big square block tanks of old which would dominate an entire room.

In order to carry out the periodic maintenance, you need to have one of ...  Read the complete review

If you own a Biorb, a service kit every couple of months will keep your fish healthy and happy and your water clear. The kit consists of a filter cartridge, water treatments and a algae cleaning pad.

I then remove the bubble tube and any ornaments which need a clean. I use a plastic pump to remove around one third of the water, concentrating on the bottom of the tank to remove waste. Then I remove the old filter cartridge from the bubble tube and discard ...  Read the complete review

I used the service kit when changing the water about every 3 or 4 weeks depending on how well stocked your tank is and what fish they are. I personally think the reef one guide on stocking levels is too high, I do regular water tests and about 6 white clouds is near the limit. The kit consists of the main case having activated carbon, ph stabilising crystals and a foam filter, the kit also contains a cleaning pad and instructions on what to do. I found the kits easy to use and clear what to do, I did find having the suction pump going near the old filter as I removed it caught a lot of the mess underneath the filter unit. I found you have to be careful as ...  Read the complete review
