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.

No, there's no need for a cannister filter.

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.

Thanks for the advice, only have 15KG of live rock at the moment so will
keep the wet/dry in place until i have managed to aquire enough rock to
remove it!

Dave,

Depending on how long you plan to use the canister until you have enough LR,
you just MIGHT be fighting a losing battle against NO3- buildup. Since you
have a very low bioload now in relation to your tank volume, I would suggest
you just remove all biological and mechanical media in the canister, and as
Kim mentioned, just use it for chemical adsorption purposes - carbon, NO3-
resins, Rowaphos, etc.
