man i just got my oceanic sump #3 ..its come with every thing but not the bio balls ......is any out there got one like my ..i need to know how many bio ball should i buy ?
i have the exact same sump, (2) of them actually and i been using plain old lava rock in one of them for about 5 yrs now and its perfect. the other one i am using eheim ehfisubsrat pro for about a yr in the other one, considering i didnt have to pay for the eheim product it is great but not cost effective. Just go to home depot and buy a big bag of lava rock and enjoy the nice sump
