Martin's 180g Reef Build

And about your Barracuda ... use lots of Spa-Flex and I mean LOTS
The more the better. I found with my 1262 Eheim pumps, even just a small piece of rigid pvc caused noise.
I have since clamped my spa to the wall with spacers to keep the rigid away and all noise is gone. Except for the return line of course. That is not clamped to any walls and is quieter as is.
