How the heck am I just now discovering this thread? 45 disc? 220 gallon tank with 180 gallon sump? Very freaking cool! I haven't read that only a handful I've seen the post here and there after the first one but have seen some cool advice that I'm actually jotting down some stuff too. And I will totally admit, I am a sucker for Threads with a lot of good pictures! Thanks and keep it up!
