Is Acropower a carbon source?
 

I know it's amino acids but it tastes pretty sweet. You can probably put it in your coffee for a healthy breakfast..LOL.

I'm wondering if anyone has experienced a drop in nitirate with it. I've read that it may cause cyonabacteria (spelled wrong). If I remember, this algae may appear when nitrate and phosphates are not in balance. Low nitrate high phosphate.

Amino acids contain nitrogen, so I wouldn't expect a nitrate drop. You might get a phosphate drop.

It is likely it has some carbon in it. The fauna Marin amino acids actually state glucose as a main ingredient.

The blurb from Two Little Fishies only mentions amino acids, but I'm not sure how much that means. If it contains only amino acids, I'd consider it unlikely to reduce the nitrate level unless it somehow allows a lot of extra coral growth. That seems unlikely. If it has a carbon source, then it definitely could reduce the nitrate level.
