Biorb tank

EmmaTheCabbage said:

Hello. I currently have a biorb and also set one up for a family member. So have had a lot of experience with them (good and bad). Similar to what other people are saying, the biorbs really are far from ideal and aren’t the best however there are ways to get around the problems. The sharp ceramic media at the bottom I have experienced is quite dangerous for fish as when I had it in there my fish damaged their tails and bodies on it when they sleep. The reason it is the way it is though is because apparently the material and such is good for benefital bacteria. It also allows poop and such to easily be sucked into the bubble filter. Getting rid of it means it’s safer for the fish but the built in filter won’t work as well if you use regular gravel. What I did was put the ceramic media on the bottom of the tank and then add a layer ontop of gravel. A 15L is quite small however I reckon you could keep a few guppies or a Betta with a snail if you buy a heater (these are about £20-30.) if you don’t want tropical, I think mountain minnows are cold water (not completely sure though). Personally I’d add live plants because plants are always great to have in an aquarium and you can get very easy ones to keep. You can also find very small filters since the biorb filters aren’t very good. To add in there too. I’ll attach a pic of my grandparents baby biorb. There’s is going very well and plants are growing good.

I'd have to disagree with the first answer and say that any gravel you use is perfectly fine. Manufacturers like to say their biological media has more surface area and smaller pores to grow bacteria, but in reality this may just mean it clogs up faster. I watched a YouTube video where someone put a piece of regular aquarium gravel under a microscope and it looked like the surface of the moon. So any gravel, even smooth aquarium gravel will have more than enough surface area for biological bacteria. Undergravel filters have fallen out of favor but they are actually my favorite type of aquarium filtration.

I also agree with Colin that you need to dump the bio orb and get a rectangular aquarium. I had a similar experience when I was starting out. I fell in love with the Fluval Edge. It looked so much better than those black rimmed rectangle boxes! But after setting it up it was nothing but frustration. Now I love the simplicity and elegance of a 20 gallon tall aquarium.

Good luck!

Hi and welcome to the forum

Is there any chance you can tank the tank back and get a square of rectangular shaped tank that holds more water?

Whilst Bio-orbs look decorative, they are absolutely useless, awful things to maintain. The small water volume also makes it really hard to keep anything in it. A normal rectangular shaped aquarium that holds 40+ litres is much more user friendly and will give you way more options when it comes to fish.

From my crash course of what those particular aquariums are designed and marketed as, they are a UGF type filtration system. The substrate they provide (looking at images online) looks.to be substantial, and porous. This will have the added benefit of beneficial.bacteria colonies having and.overaboundance of space to form. It would benefit you, and your new adventure, to use the substrate they provided. You may be even able to use some of the other stuff you got as well. But their use of the term "filtration media" is exactly what I outlined. It is an undergravel filter system that uses that gravel as a biofiltration system for chemicals, namely ammonia, converting it into less harmful stuff for fish.

@alexandraprice take a look on youtube, there is a guy on there "Pimp my filter" who has upgraded a bioorb to become more effective. I, personally do not like them but each to there own. Good luck to you on your fish journey

Oh thanks I’ll watch that now ! Yeah I’ve heard the filter is not too good , which is a shame, I wish I had done my research. Thank you !

Wow thanks so much for your help. Yeah I think I’m just gonna take out the pet store gravel and put the biorb one back in and then add abit on top. I’m only planning on having a few guppies in there and I’ve got a few live plants. Thanks
