ATI - just wanted to say that I got my first shipment of your ATI Essentials today. I have been running a 120g tank for 3yrs with ESV dosing and Amino Acids with good results. I was very excited when I first heard about your new dosing product. I have since started up a 168g Rimless tank that I will mainly stock with SPS. This tank has been running for 2.5mo now and is looking pretty good so far. I will start dosing the ATI Essentials this week, test Alk daily and Calc weekly for now.
