Biorb Review


Guest

Hi,

I'm new to the forum and had noticed a question that included the biOrb aquarium line. Thought I'd post a review on mine.

These are acrylic, spherical tanks that are filtered via a bubble column that flows up the middle of the sphere. Water is pulled through a disposable sponge/chemical filtration pack at the bottom of the column tube. They come in 30 and 60 liter [@ 7 and 15 gal] sized. At the top is a built-in halogen light [optional] and the tank can be fitted with an optional heater. Key to the filtration system is the high surface area ceramic media that supports a bacterial population for biological filtration. Orignally made in the uk, available in the usa now as well.

The pros here are the stylin' good looks--the base and top trim even come with interchangeable colors--and the fairly simple maintenance routine. You simply twist the bubble column and lift out the filter pack, replace it with a new one, and twist it back in while doing your water change. Another pro is the thriving and helpful biOrb forum on the koivision.com web site.

One of the drawbacks is that, while the packaging and advertising often shows a 7 gal tank with 4-5 happy fancy goldfish, it is misleading to think that you could house even 2 goldies in there comfortably for very long. [Though it IS a step up from a 1 quart goldfish bowl!]

I've used mine for a simple marine set-up, tropical, and as a betta tank. I've kept 2 2-inch fantails in there temporarily. I find it to be best for the small tropical species and for a single spoiled betta.

How do you find having to use biorb replacement parts? I have seen 'biorb service packs' which are over 5 pounds (uk) each, i can't remember exactly how much but it seemed expensive. Are these needed often? Also is it actually easy to clean? How do you get algae off the glass and things?

I have seen a lovely one set up at a lfs with a small shoal of neon tetras in it and it looks amazing. Great for the right sort of fish but as you say, the packaging is very misleading.

Thanks for the info,

Rachel

Yes, they are easy to clean. The service packs are quite expensive, but I use mine several times by rinsing out the sponge and replacing the carbon from my own supply. I clean it @ monthly, you need a long hancled brush to keep the bubble column clean. There are no glass parts...

Thanks for the link to the Koisision forum. My id there is Finn and I set up the first marine biOrb, and have been a moderator for that thread. It took the company a while to warm up to the idea of using them for marine, but I sent in a simple set-up routine and now they're fine with it.

sorry, by glass i meant the actual tank material, i guess its acrylic. Doesn't it get algae growing on it? how do you remove that? The marine idea sounds interesting, i'll have to check out that thread.

Thanks,

Rachel

Rachelm,

Yes, it's an acrylic sphere. You just take off the top like a cookie jar and reach in with an acrylic sponge to clean the inside.
