I have been using this system for about a month, although I have been using a small dose of NoPoX for about a year. I have been taking it slow, and am dosing like 30% of the recommended dose for colors, and about the same for the Energy product. I did some big water changes right at the beginning of using this product line to correct some serious chemistry issues (had done two 25% water changes with a box of Reef Crystals, and although it mixed up to 35 ppt, the Alk was 2.8dkh, calcium was 190, and Magnesium was like 800...didn't figure this out until I had done both water changes), and saw some immediate positive changes. Things have continued to look good, but I can't be totally sure if its the additives/system, or the further 25% water changes using their salt that have been the cause.
I will say that making the stock solutions of the Foundations (CA, Alk, MG) has been very simple, and I was able to just triple my dose of ESV B-Ionic Alk (was dosing 9ml/day with ESV Alk, so dosed 27ml/day of Red Sea Foundation Alk) and the tank didn't miss a beat (kept the Calcium dose exactly the same as my ESV dose). I should mention that I only had to use a 3x dose of the Alk because I made my stock solution using the powder, I believe that the premixed liquid supplement would probably be about the same as ESV B-Ionic.
Like I said, maybe my tank is just looking better because I have done some massive water changes, and it has nothing to do with the colors/energy supplements? Personally, I think its a little of both.
I do like how everything works together (like dosing the Colors supplements based on Calcium dosage, etc), which is the main reason I moved over to using all Red Sea stuff.
