We really dont need to toss in water every chelate we hear about. Make it sinple, use some CSM+B or TPN and complete it with DTPA, far then enough for most aquariums. Unless you try growing plants in PH+8 water, you won't need EDDHA too. On the other side, I don't think many plants will grow in such a high GH/KH water as we see in african cichlid tanks: few plants can thrive in there
I guess you are right. I do use TPN to supplement the CSM+B dosing. The EDDHA I bought as part of a group buy with Wet , to experiment with it. I guess, I got nothing better to do, for now.
