Just wondering really as i have a 125 gallon main tank (uk gallons) and a
35G sump with wet/dry and a skimmer is there really any need for a cannister
filter? I have live rock in the main display and in the sump refugium also
with a caulerpa bed for nutrient absorpsion. Hmmm.
Stocking is currently 3 cleaner shrimp, 1 Atlantic anemone (think it's
atlantic still trying to identify), 12 hermit crabs 1/2 red leg other 1/2
levimanus, 8 turbo snails and a common clown.


I would say that you don't need the canister at all, the only reason to
use it is for carbon or other chemical media.

Also on your sump, I would suggest removing the wet/dry portion of the
sump also. If you have enough live rock you do not need any extra
filtration other than the skimmer plus you have a fuge with algae filter
so you are set.
