 Amino Acids huh ... I add some to the frozen already, but guess it's not enough
If I knew why I could correct what keeps it so low

But maybe put skimmer on a timer and run it half time. I also recently read a thread where a guy was adding a nitrate salt (NaNO3??) to his tank. Remove some rock?

 My skimmer doesn't really pull much per week - a 7" cup gives me less than 1" of wet NOG/week
I have removed rock already before X-mas and am down to less than 1lb/G - probably closer to .75lb/G
