Swap out the OEM screw top with a FLIP top plastic cap.
I just flip the bottle upside down & let gravity dispense the solution 1 drop at a time.
I DONT squeeze the container WHATSOEVER. Gravity does the dispensing.
I use 1 drop/gallon & so far I haven't killed anyone so I'll stand by this measurement.
Make sure your replacement CAP is rinsed out well
. I would also HIGHLY recommend getting it from a condiment bottle in your refrigerator.
- The 1st cap is most common with hair care beauty products/lotions/shampoos/conditioner, but any residue left behind will KILL/injure your fish. Use those bottle tops @ your own RISK.
