Cut my filter basket down to 1 1/6" thickness, put it back to back with my 9002 Tunze Skimmer and slid it into the middle pocket behind my hood, with out cutting the hood. I would like to go as natural as possible. I was reading one of the threads on here said you could run a reef without a skimmer. So I don't know what I'm doing yet. Maybe I should get rid of the skimmer and build a bigger filter basket. I've got an Artic Chiller. I've got five 10" filters that I want to tap water through out of a bucket in a loop or keep recirculating till the water is clean, instead of buying an R.O. Haven't figured out what type of filter cartriges to use yet. Got a Saltwater mixing kit. Still trying to read up on all this stuff.:eek:
