I got my seachem prime today! How much do I use to chlorinated a gallon of water?

We use 1 drop per gallon

Since there's no dropper on my bottle of prime, just a crew off lid, I actually use a syringe (a real one) to squirt a drop or 2 in there. It's a fine gauge syringe. Although I'm not sure a pharmacy will sell them without a prescription. My husband has a prescription. I'm sure you can order on line.

I just poke a hole in the seal instead of removing it. 2 drops per gallon.

1-2 drops a gallon is fine. It's pretty concentrated compared to most other brands of water conditioners...
