1.mechainal filteration
2.bio balls
3.ur ceramic media
4.protin skimmer
5.uv stralizer

what oreder do theres go in and do u need bio balls with ceramic meadia and what exactaly are bio balls for and how often do u have to change em

that order seems about right.

bio balls are a biological media, they have two purposes, nitrification and gas exchange.

as for cleaning, if you have good mechanical filteration you shouldnt have to ever clean them out, otherwise clean them out as son as you notice that they are becoming covered with gunk.

i usualy see that the bio balls come b4 mechanial filteration i was wondering why this was cause to me the bio balls would get all nasty so....do bio balls ever need to be replaced

no way, bio-balls pretty much last 4-ever as they are made of plastic.

mechanical filteration should always come before bio.

What you might be seeing is some mechanical filtration between the bio balls and the return pump. This is basicallty to stop any gunk that settles in the sump from being sucked into the return pump.

You will need some form of mechanical filtration before the bio balls so they dont get clogged, then they should last forever
