Well the thing is, I dont really have anywhere to put it near the 75

 I also... have an odd situation. My nutrient levels are all extremely low, so much so that I can only keep one clam in the system at a time, I have limited algal growth, even my fuge has slow growth. The last waterchange(and only one) I did caused problems, and it was only 5g. I only top-off with RO/DI water, and I feed fairly heavily. The tank has been running for 2yrs this way, and im worried I will wreck something, lol. 
Ohh, you upgraded the BK?

 Or, im just not very attentive!

  When did you get it? 
I forgot the dims on your 300g cube. 
Are you enjoying the BK's? Im thinking about one on my parent's 400-900g room divider in their retirement home.
Thanks

 I really cant wait to see it in action! Hehe.
