Overall one of the best ato pumps By OBB on 4/17/2012

Fast enough to keep but not so fast it changes water chemistry rapidly ! The one and only flaw I have noticed w/ it is fairly loud on initial kick in, but not to loud it's livable other than that amazing ato pump guys !!!
Broken - gears stripped By Nytewatch on 4/1/2012

Bought one of these to use as a top off pump 3 months ago. It broke this weekend - gears are stripped inside. I see this has happened to others. It's a very simple design, took it apart and its just a simple motor that turns the two tumblers. Testing my finger lightly against one of the tumblers showed stopped it completely (motor turning, but tumbler assembly slipping). It appears the gears inside are cheap and that is the problem with these.
Works for me!! By Eric on 3/24/2012

I'm using it on a controller as my ATO pump. I like that it doesn't clog which is a bonus since I have kalk in my ATO resevior. I can't comment on why it's failed for others. However, per the instructions, it specifically says that this pump is only supposed to run intermittently and NOT continously. Another note is that it sounded like a freight train when I mounted it to the back of my wood stand. You'll want to put something soft between it and your stand to cushion the vibration if you go this route.
awesome pump. accurate too. By Rob on 2/22/2012

I have three of these and am just looking for an excuse to buy another. I also have the 1.1ml/m version. It's very good too but achingly slow compared to this one. Each has their own use, of course, I just kind of wish there were an intermediate speed (or two) between the 1.1 and 50.
shame on you BRS By Chris on 1/25/2012

I had this pump for about a month and it failed. I was told I had to send it in with the RMA and they would send out a new one. There is no advance exchange offer. Really BRS look in to this. Most big company have this option. I was very disappointed with this hole thing. So I order another to keep as a spare.
Broke again-3rd pump By Branden on 1/15/2012

Third pump, third pump failure. Read my previous review. This one lasted at least lasted a year and half give or take thankfully. So now 2 years from my first purchase and I've been through 3 of these pumps, all broken. Took one apart, the gears in the motor are plastic and are stripping. Pretty cheap. Anyways, most seem to be having good luck with them so take this for what you will but be warned, they may not last all that long. Too bad too because when they work they do a good job, just very undependable for $100.

I have three of these -- two for automated water exchange (2g/night) and one for topoff (2-4g/day). One recently broke (the pump head became uncoupled from the pump motor) and BRS replaced it no question. Compared to other dosing pumps this is a great deal -- relatively quiet (it does make some minor noise), great price.
great! By denis on 11/23/2011

have been using the doser w/ my kalk stirrer and it has been working precisely. good for 1.5 gallons of top off per day or more if needed. works great!
Excellent By Adam on 10/8/2011

This is a very good auto top off pump. I have this directly pulling water from my 50 gallon reservoir. The pump is very strong and consistent. This was way better than using a mag pump for this application. My only complaint is that is becomes a bit noisy if you mount it to your stand or even your wall. Because this pump is so well built, I decided to go with the BRS dosing pumps for Cal/Alk.
Great Doser By Brian on 7/25/2011

Great doser. Very easy to set up. Use it with my top off set up. Works great with the ReefKeeper controller! Slow rate prevents quick swing in salinity. Would recommend to anyone looking for an auto top off pump!

I have three of these all going on 2+ years use. IMHO all of the other dosers out there are too fast and cheep toys.
