Hello all... I am knew to this forum and fish keeping! My girlfriend and i decided to go for a 30Ltr Biorb on our initial purchase for a 'tank', as it looked attractive and would compliment our living room. We had already decided to go tropical, so set it up accordingly. We have 2 Cherry Barbs, 2 Dwarf Gourami's, 2 Long Finned Leopard Dannios, 2 Golden Zebra Dannios, 2 Silver Tipped Tetras and 2 Blue Tetras. Every time we do tank maintanence, it is a nightmare trying to remove all the debris from the bottom of the Orb. Anyone familiar with the function of the Biorb's filtration will know it's really not practical. I need to know if there is a way to customise the orb for use with an external filter system or does anyone know of a an external filter that can be used with the Orb without customisation? Please help...

A 30l tank is about 8USG. A rule of thumb for tropical fish is 1 inch of fish per USG. That would indicate a reasonable bio load of 8 fish. You have 12 fish, some of which will exceed the 1 inch parametre. You are sadly overstocked and if additionally you have a filtration problem you are headed toward a disaster. I don't understand you filter issue as I am not familiar with either the tank or it's onboard filtration system. You need to investigate augmentation of the filtration system and probably should also investigate returning some of the fish.

Practically perfect in every way
unfrotunately the filtration on the bi-orb's is reknowned for being .... well.... rubbish to say the least.
to counter this you have to be very very careful with your stocking and not add too many fish, as Vic's said you have way to many fish for that size of tank, even with good filtration. for a bi-orb your very badly stocked and this is probably the biggest cause of your problems.
to give you an idea of what your current stocking is and what it should be here's a few details.
as vic said you need to aim for 1" of fish (worked out on theyre adult size) for every 1us gallon.
2 Cherry Barbs, 6"
2 Dwarf Gourami's, 6"
2 Long Finned Leopard Dannios, 3"
2 Golden Zebra Dannios, 3"
2 Silver Tipped Tetras 3"
2 Blue Tetras - not sure if you mean neons?... if your lucky and they're small then 2"
so that's 23" of fish.... you need to aim for 8.
in additon to this, the tetra's and danio's need to be kept in groups of 6+ of they're own species. danio's like a lot of swimming room so need a 25g tank minimum, dwarf gourami's can be agressive and don't do well kept in pairs, should be 1 on it's own or 1 male and 2 females. cherry barbs also do better in a group of 3 and also like a lot of swimming space.
in that size bi-orb i think you only have 3 real options for stocking
1 - a shoal of 6 1" fish something like small tetra's or rasbora's
2 - 2 shoals of very small fish like endlers or microrasbora
3 - a single specimin like a dwarf puffer or siamese fighter fish.
I'm afraid even with better filtration your bound to have massive problems keeping these fish in this tank.
Bi-Orb's are also nigh on impossible to fit extra filtration to due to the shape of the tank, internal filters won't stick to the sides as they're designed to fit on a flat sided tank, externals won't as there isn't room in the lid to fit the pipes through.
sorry to give you such bad news

Sadly, i have to agree with everyone here.
I have a Biube (the tall flat 35l version) and am cycling it with 2 danios. Even once i've cycled the tank, i'm not planning on having any more than 8 fish in the tank. Simply because (as everyone has said) its a small tank and isn't designed for a large amount of fish.
If you've bought the tank and then added all these fish straight away, you're heading for major problems.
Did you cycle the tank before adding fish? If its been cycled, i would say take some fish back and work your way from there.
