I have and oceanic bio cube 14 gallon which is ok so far (knock of wood

) i rearrenged the filter and where all the bioballs go i stuck a bag of filter carbon and a big piece of filter floss and a stuck the rest of the bioballs that i moved into the area where the pump is stored. I also added a fancy molecular ionazation ( cool word

) unit to the tank by using fishing line, sucction cups and a bit of common physics. the tank has been running for about a month and a half and everything seems fine i have added a fish and some corals to it and i found some really cool stuff on my 14 pounds of live rock ( for decoration and filtirazation) I also spotted a bunch of cool stuff like little worm thingys and some little protozoans using one of my microscopes( the live sand is also for decoration and filteration, i have it 3 inchs deep exept in a area bettwen two rocks which slops down gradually and is meant to immitate a little cave for my orchid dottyback which is by the way the cuttest thing ever

. So after my monologue which i almost fell asleep my self in the begging z z z z z z.

just kidding, but ya all in all the oceanic bio cube series is really great and with a couple of little customized things i am sure if you get one yo will love it.
