Can someone check my math? Safeguard aquasol for small flock

[buffy-the-eggpile-layer]

I'm skeptical of my math abilities and I'm worried about massively overdosing my flock due to miscalculation (x the unforgivingly high concentration of safeguard aquasol).

I bought a small portion of safeguard aquasol, which is otherwise very expensive because it's typically used for farm/factory populations of chickens. Below is an image of the instructions that came with the bottle (with my math) and the safeguard label itself. I did round up very slightly.

I appreciate anyone who can riddle out the puzzle and let me know if I'm on the mark! Thank you!!
