new sump for my 8 x 2.5 x 2.5 arrived its 6 x 2 x 1.5 and was just wondering wat if it would be ok to fill it up in this order so 1st compartment on each side with bioballs with cotton on top of them then the next two compartments from each side japanese mats and then finally the big compartment on each side filled with ceramic noodles and then the middle is just where the pmp goes. my tank is plumbed with two 2 inch holes in the back which are over flows and a 1 inch hole as a return with a spray bar going along the whole length of the back of the tank
