Need advice on 2 part dosing

[Dash]

Thanks for the input Glen.
After reading around, checking prices etc, I think BRS is still a good way to go, for me anyway. It’s a good straightforward product. I just watched a BRS video on “best” dosing products and it looks like BRS stuff came off pretty good. I am interested in trying out Tropic Marin Part C as they suggested, to add trace elements. Brightwell is also a good option and might be the way to go if borders don’t open up soon
Picking up stuff across the border worked well for me, and even with the dollar exchange, saved me a lot of $$ as well as the fact that you can’t even find some of the stuff in Canada. Hope this shutdown doesn’t go too long...or else I will have to ask for 2-part recipes!
