BRS media reactors - input from owners please

I don't want anyone to be mislead by my previous post as my diagnosis was incorrect. It has nothing to do with the cartridge sealing gasket

What 1eyedjyde said makes perfect sense

After days of still getting air in the reactors I think I've found the issue.
My pumps were quite close to the last baffle and it looks like they've been picking up micro bubbles. It was never an issue with the TLF150s as any air introduced can burp out on it's own, but the 'RO' style canisters trap any introduced air which then builds, and builds and ...
I had to use a flashlight with my sump room lights off to spot the bubbles

I've moved the pumps as far as possible away from the baffle and hope to report back that the issue is solved. I'll give it a couple days before I do so

I'm loving this reactor style for ease of use, and in my case the spread through the media is far superior to that of the TLF150s
