Had a quick question about your experiences with CSM+B. I am dosing Seachem Flourish for traces and Iron. I am getting some new growth on my Repens which is yellowing. I think this is Iron deficiency. I would like to try CSM+B but don't have any experience with it. I have read that it still lacks in the Iron department. I am getting quite leary about info on the net and wanted to know what you, the people who actually use it and have experience with it, thought about it. I ask because I want to know if I should use CSM+B or should I just continue using Flourish but start adding Iron Chelate 10% ? Thank you in advance.
