So I have been working for 3 weeks almost every spare moment i have on getting this cube setup. I was plumbing the closed loop and somehow the back panel cracked in about 4 different places. I could almost cry. I had bought everything I needed and was at the point where I didnt have to spend anymore $$. This reefing thing has been fun but I have spent too much time and money on it. Look out for a new thread - I'm selling EVERYTHING! Margi take me off the Macna deal. Who knows i might get another nano cube and be done with it.
