Not sure if it is fair to write a review after only half the product has been used, but on the other hand the bottle says results seen 24-48 hours after dose.
I see no difference in PE, color, growth...anything really after using the entire KZ line. My tank is full of SPS, all with good color, good health and growth. We've all seen the photos of pastel tanks....not the case IME with these products. They haven't done anything of note since starting the regimen.
