1 week waiting for someone to return my message left on the reefbreeders website regarding my coralbox doser. 3 days later contacted via Facebook and phone voicemail and still zero return call or even IM for help. Meanwhile my tanks alkalinity is plummeting. Guess I'll have to whip up a batch of baked baking soda and manually dose while I listen to my doser make annoying beeping sounds every 2 seconds!!! Huge disappointment
