I think by three-filter types he just meant chemical, biological, and mechanical (I'm hoping those are the words he used).
Another question:
I'm trying to decide between an all-in-one unit like the oceanic biocube nano (24 g) or a piece-meal regular aquarium. My father just got the biocube and it looks great. Seems relatively low maintenance, etc. However, there are limited possibilities with upgrading parts because it is all built in. What do you all think?
I asked this one somewhere else too so sorry if you are reading it twice: Anyone used Tampa Bay Saltwater for live rock...what did you think?
