Ok, so if I am going with a 295GPH pump w/ 69" max head. 1/32" channels, 1/16" fins (maybe smaller) and about 7 fins. What am I looking at?
Another thing. I want the fin hight to be 3/8". Maybe w/ this hight I should make 1/16" channels?
Here is the latest drawing of the block!.
Do you think I should do something different? What are you suggestions?
