[1.12.2] Auto-break Openblocks Tanks?

[Flexico]

I've tried Computercraft turtles and ProjectRed block breakers, and the tanks lose their contents. I tried the Openblocks block breaker, but it doesn't respond to redstone; it just instantly breaks anything in front of it. Is there any way to do this?

It’s weird that some things make it lose its contents! Could you use something like a mechanical user with a pickaxe in? Mind you that will depend on the configs as to whether the User as a fake player will work.

Actually additions has a Redstone responsive Breaker.

Why are you after breaking an Open Blocks tank instead of say an ExU2 drum?
