Unless you have undetectable levels of NO3 do not use this product. It contains NO3 and it is not stated on the label.
Still early to say, but seems promising! By Fred on 10/17/2015

It has only been 2 weeks, but I can say that my purples have seemed to get richer and I can surely see an improvement in overall coral coloration.

As a user of the zeovit system, this product can make a huge difference in the appearance of corals. Starting off I had some very pail corals due to lack of nutrients. After dosing this product every other day for 2 weeks all the color has came back. Very good stuff.

Im running zeovit on a 200 gallon reef tank and was having trouble with purples and a few validas being too much on the pale side. After doing some web surfing I decided to give extra special a try. After about 2 weeks of dosing opposite of pohls extra I can definitely say the color in those corals are coming back. If you are running rox carbon I recommend dosing extra special to ensure your corals are getting enough nutrition.

This product, while expensive, is great for tanks that are very clean and need nutrients. It will add a bit of phosphate but it is negligible as long as you maintain quality water. Great for SPS. I noticed significant growth in my acro colonies.
No noticeable effect By Trevor on 4/21/2014

I have dosed a 250ml bottle of this additive and haven't noticed any effect on my corals. After I stopped dosing I didn't notice any impact. It just doesn't really seem to do much.

So I have been dosing XTRA Special for 2 years. I noticed better colors within about two weeks of starting. When I recently ran out I figured by tank is older and more stable so I don't need it. Within a few weeks 3 of my larger colonies lost their fluorescence and color. Within a couple of weeks or starting to dose again, my colors in those colonies are coming back...
