Hi lads,
i just built a 2000L indoor pond fr my silver arowana which is currently in a 4 foot growout tank. I do not have much experience with pond filtration. This pond will be stocked with a silver arowana, a cigar shark, a tinfoil barb and maybe 1 or 2 more fish in the future. Can you please tell be how many bioballs i will need if i build a filter using a barrel. Im planning on using a 6000L/H pump. Is the flow rate good enough?
