^..^ bandit I find running carbon in a canister works best!

As for PE I think if you look on RC you will find that vodka sugar and vinegar mixed with aminos will give you great PE. I run ultralith and have good PE on my sps but heck was dosing aminos before and had great polyp extension back before I started UL. Try aminos first and see whatever you do start with small amounts and slow.
