starting a 92g corner tank that is reef ready, aga, w/factory overflow. i also have a drilled 20g long tank yhat was set up in a lfs. it is drilled in back glass one high and one low. i have been researching for weeks on this site and would like to use this 20g for sump. my question is , do i still need a skimmer if i have an overflow?thanks in advance and if i do what should i buy?
