hi guys and gals, as some might know i currently do not have a sump. i run my DT with 2 canisters. been quite successful for a year now. the higher ups did not approve my plans for a 3m x 800w x 650h, so i got me a moerse sump so i can increase water volume and a bigger skimmer, Chiller, add more fish and coral and and.. looking for some ideas as to the chambers in the sump, i want a dsb as big as possible, i believe the success in my setup is that i have app 7cm deep substrate mixture of aragonite and beach sand in the DT. thanks in advance for constructive input.
