Absolutely guaranteed not to back siphon, these dosers use a quad roller system as apposed to a dual roller system like the Aqua Medics etc. Two rollers are pinching the tubing at all times as compared too one in other even more expensive dosers that are available.

These pumps do not come in dual and need to be bought in pairs or even three if you also choose to dose Magnesium in this fashion. The best timers to use are the digital timers that are adjustable by the minute.

O.C. Also has the timers available online under the "controller / Timer" section.
