Amino Acid confusion....

[Diesel]

because nitrate is necessary for optimal coral health and vigor; zooxanthellae require it. I also maintain a mixed reef so keeping it towards the nutrient poor side tends to not produce great results overall.

Even SPS dominant keepers will tell you that you need some nitrate. 2.6 is definitely on the low side.

Oh I know that.
But why so high?
Don't you watch how your corals react to a level of No3?
It's easy and done to put a # down but every tank is different.
In my case with 2.0 you play it safe especially if you don't have a whole lot a SPS.
My tank runs between the 2.0 and 4.0 give and take and I don't know how to stop my corals from growing not to mention my colors, and it been there for years.
If your tank needs 10 that so will be it, IMO that's asking for algae problems but again it's your tank.

IME I would say 5 is decent for nitrate levels...

As to the OP's question, amino's are very easily overdosed. I've seen more than a few stories about amino dosing that ended in full-tank disaster. So no matter which you use, watch the corals more than following the instructions on the bottle.
For my own tank, I've used acropower, zeo stuff, and finally settled on reef energy. There's a bit more than just amino's, so it's all I really feed my tank on a regular basis. Colors are amazing, and I've not been jealous of anyone's tank for quite a long time now.. :)

just the other day my nitrate was at 15 and not a cyano speck or otherwise present... elevated phosphate seems to have a much more pronounced effect, qualitatively speaking.

5 is a good middle ground, but just wanted to make sure you didn't think your nitrate was high at 2.6ppm...

Nope, I thought it was low...
