What is the differance between sump and canister ?
<<A sump is another aquarium or storage container which increases water volume and provides a place to keep the equiptment. A Cannister is an actual filter unit itself>>
They do the same job right ?but isnt it easier to use a sump then canister?
<<Only when there is a refugium added to the sump does it then technically become a filter. So, in that configuration, yes, a sump/refugium is the same as a filter in a round about way. People still keep a maintenace routine on a sump...But, predominantly, more work is required with a cannister filter>>
If we get the 29gl bio cube ,would it be worth it to run a sump on it ?
<<If the space is available, yes, i think its always worth it>>
How often do u need a new canister or do you just clean it like a skimmer?
<<You dont need to replace the actual device, just the media, replaced over a month period. Skimmers just need the collection emptying down the sink ( i personaly prefer to take skimmate shots
)
Thanks
