Measuring spoon and dry dosing question?

[Glouglou]

I want to simplified my life and want to dose dry. Need to find what to buy...

In small amount measurement what are the combination of measuring spoon are the most used?

Ex:
Tadd = 1/4 tsp
Dash = 1/8 tsp
Pinch = 1/16 tsp
Smidgen = 1/32 tsp
Drop = 1/64 tsp

Do you generally use all of these?

Tadd = 1/4 tsp
Dash = 1/8 tsp
Pinch = 1/16 tsp
Smidgen = 1/32 tsp
The last 2 only if you have tanks below 40 glns.in my opinion,& of course the larger spoons ( 1/2 , -1 TBSP if the tanks are above the 50-60 gln capacity.
