i'm using 1200l/hr return pump plus 800l/hr(i think) wave maker... so far ok.. i see my SH playing with the current where the flow is stronger. like wave surfing.
Do consider using overflow n a sump where all Ur equip in it in the near future. Cos u will soon find u will not hv enough space. for Ur favourite zoas.
