Thanks, I'd appreciate it. As I'm sitting at my desk this evening, it really struck me how quiet this finnex canister filter is once you get all the air out. Granted, I have it sitting on a foam mat to prevent vibration noise but it seems at least as quiet as my 2213 and it's much closer to my head.
I have the Atomic Nano V3 regulator, with an adapter to a 20oz paintball tank. It works really well, though I have a few issues with it--mainly the lack of a high-pressure gauge. Since working pressure is fixed it would make much more sense to see when the tank is about to run out then to see the working pressure.
Here's a cell phone snapshot of my filter/CO2 setup, sorry for the poor quality. I've used a milk crate to reduce the length of filter hoses somewhat, since it seems to slow down some with longer hoses (regardless of height). The milk crate also makes a convenient frame to zip-tie the CO2 canister in place and prevent it from getting knocked over.
Since the filter etc are in the corner under my desk I haven't taken much care about how they look--though I should probably try and improve that somewhat.
Happy 2013 everyone! I've been pretty busy since the holiday, and have been neglecting both the tank and this thread.
I was away for a week over christmas, and while a coworker volunteered to feed the fish a couple of times I didn't want to complicate things with adding ferts. On coming back I was surprised to find that green algae on the glass was the only problem that had developed.
I've been working on it, but you can see it's still a long way from gone. I think it will just take some time to stabilize again now that I've restarted fert dosing. The whole tank also badly needs a trim--hopefully I get around to doing it some time next week.
