I highly recommend this product in conjunction with the CaribSea Aragamilk. If you use a buffer with a pH stabilizer to keep your dkh at 8/11 with your pH at 8.3 along with using CaribSea, you'll get amazing results. May I also recommend testing your phosphates, make sure to keep them at appropriate levels. If you take the above into consideration your reef aquarium will begin too thrive, and your coral frags will actually begin to grow! Thanks Ryan San Clemente, CA!
