Hi All,
I have been asked a question regarding CSM+B and yellow water.
I have never seen yellowing of water beyond concentrated mixtures, but I use a lot of peat in my substrates so it is possible this is common and I just have not noticed or am not sensitive to the discoloration.
Another possibility that occurred to me was lighting, my lighting is in the sunlight, high ambient and 5000 k to 9325 k ranges, those ranges may tint the water differently.
A suggestion had been made regarding a change from EDTA to DTPA chelate. I just do not understand enough to know why EDTA would discolor the water and DPTA would not. I have used both and I do not recall a difference in water color.
I think I recall reading something about certain water types reacting with CSM+B.
Any thought would be appreciated.
