Ive got a 60L BiOrb and havent got a bad word to say about it. Stunnin' Tanks! And all is Dandy! I have learnt to accept the fact that there is a lot of people who just dont like them for some reason to another. Dont knock it untill you've tried it guys.

+1 on this comment. I bought a 30 litre for my very first tank but upgraded it through reef one to the 60 litre and I got it much cheaper as I had all the stuff I needed bar the bowl. I have 2 very happy colomesus puffers, 3 female and 2 male cherry barbs and a corydora juli. If you keep it simple and have a strict maintance regime then they can be quite rewarding. I do a 50% weekly water change and change the canister and air stone once every 4 weeks and never had a problem
