I just read on the RC reply thread that the assumption is 2 part
"can have" the same elements that is in true balling.
This is where 2 part/ 3 part fall apart as there is no assurance to what you are dosing, there is "an assumption" its also a balanced system, BUT there is nobody to stand behind the assumed elements.
Anyway I think this could go epic if I dont close this so i will close with my personal thoughts which kind of already state what i said before.
This is my belief of history I write this for fun and just to put some light hearted thought into the whole debate.
Hans developed a marine chemist way of adding supplements in a balanced way
The desire for DIY took hold and the only two elements freely available were calcium and sodium bicarb.
NACL free with the trace elements Hans-Werner originally developed was forgotten as its not available in DIY format.
DIY became popular as its cheap, nobody for years questioned this too loudly.
Hans-Werner probably through frustration decided to commercialize his scientific system and is now fighting against the spawn of his orginal system which has been cut back to the bare bones employing often ungraded salt and unknown quantities iif any of minerals.
I will leave you the educated hobbyist to decide which system them feel is best for them.
My wife also wants to see my tonight not stuck to the PC. if you have any questions either email or call me you know I am always available to everyone
Thank you to everyone for listening, please make your own thoughts as what is best for you.
