Just so I'm sure I understand how these work
There are two tubes that come out of the pump, one goes into the container of a liquid you want to dose and the other goes into the aquarium. When the pump is on, it will "drip" x ml/minute of the liquid into the aquarium. Therefore, using a timer, you turn it on and then off after it doses the amount you want. For example, if the pump is rated at 1ml/minute and you want to dose 3ml per day, you just use the timer to turn the pump on for 3 minutes once a day?
Is the above about right? If so, how does one "prime" the pump? I mean in order for it to start dosing, the liquid must be drawn up from the holding container and then into the aquarium no?
Also, because of the way the pump works, it can actually be under the aquarium, in the stand?
