    After reading on this forum about everyone using prime, I ordered some, and received it saturday. Today is my day for water changes. I want to use it and feel dumb, how do u all measure it out. I have a 15 gallon tank. they say 1 capful is 1ml, and is for 50 gallons, so do u all use a syringe to measure out a smaller dose.

    I usually buy Prime in the smaller bottle with the dropper lid. 2 drops treats 1 gallon. It's a bit less cost effective, but it's much easier to measure out.

    I think the larger ones with the cap measurements have little markings on the inside for smaller amounts, but I may be thinking of another water conditioner.
