Thanks Snrub! Your description in a related post of your setup about cfm being negligible to two diffusers vs. one is most helpful. I am going to refrain from using a two-disc and only use a single Matala 9" with base for the same reason.
I'll get A poly board for a base and attach as you rigged up for maintenance when needed. I am only going to be pushing a max of about 2.4cfm to it from an HK60L pump through probably 25' of 5/8" weighted hose. I'm itchin' to get all this ordered today, so I REALLY appreciate the illustrated insight of your installation.
Chuck
p.s. Thank you for writing well in your posts.
