So I've been messing around with 3D designs for little useful trinkets for the old reef. One thing I've noticed is that a lot of the food from my automatic feeder ends up riding the surf straight into the overflow and just rots in the filter socks. I've now designed a feeding tube which should eliminate that.
Question: how deep under the surface do you think it should go to allow the food to sink?
