Dosing question

[target]

I'm beginning to look into dosing my reef, wanting to see some coral growth. I wanted to get opinions on what to dose with. I'm looking at either the 2 part from reef supplies:

Or the 2 part from bulkreefsupply:

Currently I don't know my levels as I haven't started testing yet. I'm just wanting to see what everyone's experience is with the 2 products listed. Or is someone has another suggestion as well. Thanks
