I currently use Excel and TPN+ and I'm thinking of switching to AE's Aqua Carbon and Aqua Nourish+. Does anyone know if they are as good as my current ferts and carbon and are they to the same concentration as after lookjng on their site it looks like the carbon is the same but the nourish looks watered down as it says use double what you use of TPN+ daily and if it's half strength and half price I may as well stick with TPN+ as I dose an extra ml daily as it is. What you guys think? Anyone with experience with it?
