Check out www.reefdosingpumps.com. I have the 2-channel model, I think it is called the Admiral, and have been pleased with its' performance. I have nhad no trouble and it has been running about a year. HTH
I will second that. I had that one until I changed to a Calcium Reactor it worked well.
Never had a problem. I did find for the amount I dosed that I had to dilute the Bionics to get the right ratio it will only dose at 1ml per hour (or more) and is not timer compatible So say you need to dose 40ml per day then you will have to figure out the ratio
BTW watch e-bay he sells them on there a lot cheaper than on the web sight
