I know normally the bigger the better. I will have plenty of rock and biomedia in my tank. im setting up a marineland 125 gallon corner dual overflow. i'm looking at the bashsea SMS-3015 smart series sump. will this work for my new DT or should I go the next size up? I have a lead on a used Bashsea sms-3015 smart series sump.. but if I should go bigger then I will look at other sumps also. but the Bashsea looks dang beautiful.
