Questions on setting up Drew's Dosers

I just received two of these dosers in the mail. The tubing coming from the containers do not have air bubbles in them but on the outlet side it does. Is this normal? Im assuming this would effect the amount of two part coming out. Is the way I mounted them fine? TIA

Depending on how you set it up to pump, the outlet may not be filled with liquid all the time as air will go back up once the pump stops moving..

Right now both go on three times a day for 2 minutes at a time. The liquid stays at the tip of the outlet if that helps.

How big is this tank? What are you using to control the on-off on these?

Test your Ca and Alk every three days, adjust the timing device until you get it dialed in and you should be fine. Few extra drops or few less won't shift the numbers that much, I'd be more concerned on how accurate the timer is.

The tank is a 40 breeder. I'm using my reefkeeper on multi-timer so it comes on three times a day.
