Cant get dosing pump to work

[reefermadness]

The user manual is most likely wrong about the 220v because it comes from EU. If the plug is the same type of prong as here you are probably good. Check the back of the unit it should say 120v 60hz. Then simply plug it in to test it.

From what I've read coralife timers are notoriously bad. Are not even digital. You will probably need something that can time down to the minute because these pumps move pretty fast 30ml/min I beleive.

I have a aquamedic twin doser and personally I would not recommend them. You should have got the drews doser. The drews doser pump does not syphon and the aquamedic will so you have to be careful the way you set it up and use check valves that can fail.
