Prime, Purigen and tap water conditioners

[volionkeeper]

Can Prime be dosed in drops instead of cap per 50 gal of water? I have nano reef tank and water changes are measured in 1-2 galons.
Also, what other tap water conditioner can be compatible with Purigen: I didn't see other brands marked with amine based polymer as ingredient. For example Tetra AquaSafe, that I used before, lists sodium hydroxymethane sulfinate, polyvinyl pyrrolidones, organic hydrocolloids, organic chelating compounds. Can compound with such ingredients be safe to use with Purigen (or other similar specific product)?
Thank you.

Our 50 mL bottle has a dropper style lid. It requires 2 drops per gallon of water. Keep in mind that drops vary in size depending on the size tube they are coming from. Perhaps you can find a eyedropper that has measurements on it. If you can find one that shows 0.1 mL increments its even better, each 0.1 mL treats 1 gallon.

A great thing to use when needing to measure out small quantities of Prime is a infant syringe that comes with infant meds (or ask your pharmasist). I realized this by accident when trying to figure out on on earth to measure out for one or two gallons... works great!
