Just upgrading to a new 180G Show Tank from my 90G current. In the process of building out the filtration system and I am VERY strongly leaning towards a double canister (2 units not nested) closed system.
Tank is Glass and un-plumbed, so I can set it up however I choose, but it is pre-drilled with 4 holes in the back (2 at the top and 2 1/3 down).
At this point I wanted to put an open question to the community on which of the canisters you would go with and WHY
Option 1: Pair of these in line from Red Sea
(1 with Carbon 1 with Filter and UV
Option 2: Split the line and run half the H2O through a pair of Nu-Clear
(1 with Carbon 1 with Filter) and the second half bring pushed through a separate UV
Thanks In Advance.
