I added a sump in my system and was very happy. As said you can hide heaters , skimmer , auto top of unit. Possibly add a fuge which can help with your N03 and also a nice place for pods to grow. I would not have a tank without one again.
So best bet is to ditch my canister filter, add a 20 long for a sump and possible add the following
- heater
- carbon filter sock
- gfo filter sock
- UV sterilizer
- filter sponge
- small fuge (or put another tank in series as a fuge)
Good idea or no?
(I don't like running a skimmer btw.. too noisy all the time)
