I was recently looking around some websites and found that they have protein skimmers and UV
sterilizers for my 14 gallon Biocube. I have one maroon clown, a BTA, corals(3), and some inverts. i really want to know if it is a could decision to buy one or both of them or at least know which one is more important. Any advice is appreciated.
PS: How often should i replace my light bulbs? They are compact fluorescents.
