How to calculated dosing Prime for less than 5 gallons?

[Lt.]

My Prime is in the SMALLEST bottle they sell it in, and I've had it for a year.

P.S. I just checked my prime, and it is 2 drops per 4 liters, or 1 gallon.

The 1ml medicine syringes the drugstore gives you with an infant's perscription also work well. just ask for some and they'll give them to you.

+1 to what Severum Mama said. I do the same. 2 drops per gallon. I have a big bottle for my bigger tanks and refill my smaller bottle from it for smaller water changes so I can drop straight from the bottle. Makes it easier.

Holy Cow I have been using alot of Prime over these past few months!!! 2 drops p G is what I'll be doing now. I would easy go through a bottle in 2 months. I've been adding a cap full to 10 gallons!! Just for WC --- I have 4 tanks (big).
Going to get a dropper today
