I got ahold of 2, 55 gallon barrels. 1 is going to be the bio filter, and I thought the other should be a vortex/settling chamber. This is for my wood pond that holds about 1000 gallons. I found this DIY plan on the boo and hiss forum.
Ok so my question has to do with the bottom cone. Out of what should it be made and how? This guy used some calculator from sombody and gave a link that didn't work. Its supposed to calculate that angle and the dimensions for the right size cone to go at the bottom of the vortex. He started out using vinal flooring (?) but then swapped to aluminum.
Anyone have any ideas on how to rig up the bottom cone for the settling/vortex? Also what are your opinions on this design? Think it might work?
