Comments: Over the last 20 years I've owned many different dosing pumps in all different price ranges. I have gotten rid of them all and now own 4 of these wonderful pumps. These are the only pumps I will use on my 300 gallon reef, as well as the ATO on my 60 gallon cube. The Sentry is a no frills incredibly accurate workhorse. Its a refurbished medical dosing pump. I figure if its good enough for hospital usage, then I can trust it on my reef. NOTE: It is important that you read the instructions carefully, this pump can be very versitle if you know how to use it.

Comments: I bought this pump to dose small amounts of additives into my reef. Like most advanced aquarists (I hope) the pump was programmed into my controller (Apex) to try and tweak the amounts added. I will say that the pump is easy to set up, consistent in its dosing, and relatively quiet. Two major drawbacks, particularly for this price, is that it cannot be controlled by the Apex (or any other controller) and the battery backup it has. The manufacturer essentially took a hospital IV pump and slapped a sticker on it that reads A battery backup is good when grandpa is getting his antibiotics and the power goes out but in reefing if the power goes out you probably do not want additives to continue to be added, may it be because of a power failure or because a controller turned it off. I have a float switch that came with it that was made from the microphone jack used in computers. Despite its positives I have to give this pump a low rating for the little thought the manufacturer gave to reefing in particular- if you cannot control the pump then it should not have a battery backup. After a power failure you need confirmation that the system is OK and not to be "reliably" dosing additives.

Comments: I have a Sentry but want to give a warning I think all should be aware of. If you are dosing something, kalkwasser or whatever, and it is dosed with a controller, if you loose power the controller will no longer be able to direct the sentry doser which will operate by the battery back-up and continue to dose. Keep this in mind. Nice system but can overdose your tank if you loose power and am away.

Comments: This a is a very easy pump to setup. The pump is super quite and is perfect for the to part dosing that I am doing on my reef tank. The Pump was missing the light sensor and I called Innovative aquatics and Stan is shipping me the part right away. So very good customer service.
