I just bought a Rena XP4 for my 100 Gallon to replace my magnum 350. We just moved to a new home and I have yet to restart my tank but want to be very choosey at what kind of setup I want to run. Any tips you may have about the Rena XP4 filters would be appreciated as I have never owned one of these. is there anything i should know like how to correctly fill the 4 media baskets ? I know the coarse pads go on the bottom and the fine pad goes up on top. My questions are the middle baskets which have a divider in each one. I am thinking the divider is to put on top of the bio-media to keep it in place however, the drawing on the box shows media both on the bottom & on top of the divider but the instructions don't. can you experienced XP filter owners tell me what method works best to fill the center baskets and what kinds of bio-media do you use ? Mine came with some stars. Also, the bio-chem zorb, is that used in place of regular carbon ? My independant fish dealer sells rena filstars but says you CANNOT get parts for them is this true ?
