Micro ferts

[riioKen]

Hi, im going to DIY route for cloning the APT3 formula, but i can clone it only for macros, im a bit afraid to mix micros because i dont want to kill all my shrimps, do you think that a premixed would work?
I was thinking into Seachem Flourish, Masterline 2 or Tropica premium. Which one do you suggest me? I live in EU but seems that i can't find a good dealer for micros, this is Solufeed Sodium Free TEC UK based but probably import and tax will kill me, is anything similiar inside EU?

I've bought dry ferts from planted box, but he calls the micro "trace elements" so I don't know which compound it is, should I mix it at suggested dose?

I think the threat of copper in micronutrients is very overblown. The level required for copper toxicity in shrimp is far higher than the minuscule amount you'd be adding via micro dosing. I have cherry shrimp and have used csm+b and seachem flourish at ei levels with no problems….they’ve gone from 20 to over 100.
