typically when people upgrade to a sump, they ditch the canister or fill it with live rock, occasionally use it for carbon etc.
they are supposed "nitrate traps"
Yea i agree with everything you said i run a sump as well and i didnt think it was a good idea just because they are nitrate traps and he isnt very diligent in cleaning and tank maintenance. He hasnt cleaned his canister filter or changed the media in six months and heis dt is an algea farm.
