Here’s what I have to work with in the overflow box. There are two 3/4” bulkheads and one 1 1/2” bulkhead. My plan is to do a hybrid bean animal/herbie drain. I toyed with drilling larger holes or using the big drain as the main siphon but settled on going with the two small drains as siphons and the 1 1/2” as the emergency. I got some good advice on the forum that helped me come to that conclusion.
Been a long time since I’ve updated this. Tanks been up and running for several months now. I’ll post some updates and more pics.
