BRS Top Off Dosers are intermittent duty pumps and not meant for continuous operation. We recommend on/off cycles under a few hours to maximize life span. This is a higher RPM motor than the BRS 2 Part Doser and may make a small amount of noise in operation but is much quieter than most dosing pumps in this flow rate range. Mounting the pump to the inside of a wooden stand will amplify sound.
Temporarily great pump By Mark on 8/17/2017Mark would recommend this product to a friendThis pump will do a great job until an internal gear gives out and the whole enchilada goes south. Mark's re-engineer-it dept says: make that gear out of a BETTER MATERIAL and all will be well, Duh!
Lasted 6 years By Santa Monica Filtration on 7/24/2017Santa Monica Filtration would recommend this product to a friendOur gears just stripped out today, after topping off with lime water for 6 years. Never replaced the silicon tubing either. Yes it is a bit noisy, but we just cushioned it with foam and it's fine, and also the noise reminds you it's working.
Great pump By Paul on 6/16/2017Paul would recommend this product to a friendThe cost may be high for a pump that has no replaceable parts other than the tubes. However I have gone through 2 of these pumps and am on my 3rd. The second one started making gear noise so I knew I needed to replace it before it went. I use mine for top off dosing and have it attached to my Apex controller so I can program it so it doesn't wear out prematurely. I have it set to wait 10 seconds before turning on to eliminate water movement false starts. I also ensure it runs an extra 30 seconds after the float switch turns off to ensure there's a longer period before it needs to turn back on. They seem to last 2 years before they need to be replaced. Also they perform best when the tubing is replaced about every 6 months or so.
Don't expect to last forever By Dave G on 12/16/2016Dave G would recommend this product to a friendUse for Kalkwasser. I'm on my third one. On average last about 18months before the gears strips out dispensing about 2 gallons per day. Still when you factor in the higher cost of better options you can buy several of these before you would ever break even. Seem to go on sale fairly frequently ( expecially Black Friday ) so I plan ahead and buy a backup when on sale.
Working for my application By Chris on 12/6/2016Chris would recommend this product to a friendI'm using this as a basic topoff pump for a small reef tank...fed from a 5 gallon bucket that is in the tank stand. On/off times controlled by my Reefkeeper. Working fine for me for about 4 months now, although it is a bit noisy (I set it to dose late at night so...not really an issue).
Not sure how it would work for a more complicated installation with more head pressure required.
2nd Pump died just out of Warranty By MACEY on 3/10/2016MACEY wouldn't recommend this product to a friendFirst one died and it was replace quickly and easily by BRS, but now second one has died and the warranty is still tied to the initial purchase even though they sent me a new pump. Worked good while it lasted, pulling about 11 feed of head (well within the 20 foot rating). Looking for another alternative.
Great Top Off By Tiberius on 3/7/2016Tiberius would recommend this product to a friendTops off your system slowly so you don't get swings in conductivity. If you want this pump to last longer don't let it run more than 10 minutes at a time. You can do this with an oscillating function in apex. Ex.
OSC 000:00/010:00/005:00 Then ON
If Sw1 CLOSED Then OFF
If Sw2 OPEN Then OFF
Depending on the polarity of your float switches.
Pump Does Not Last By Robert on 2/23/2016Robert wouldn't recommend this product to a friendFirst pump i purchased about two years ago, and it lasted 16 months, second one is now running for 5 months and i think it is going to die to, won't buy another. I use these for ATO, will look for a better solution maybe lifter pump!
Not good as ATO pump By thomas on 1/19/2016thomas wouldn't recommend this product to a friendMy situation is not the norm so this may contribute to my problems with this pump. I draw water from 11 feet below in order to top off evaporation in my main tank through my sump. This pump is not good at this. It is too slow, loud and only lasted about 5 months. It seems like it had to run at least half the day in order to keep up with the evaporation in my 93 gallon cube.... Just terrible.
I bought a Diaphragm pump instead with a pirate flag on it :).. In my setup it is extremly fast.... It just ran for 10 minutes to fill up my sump after a 2 days of evap... the BRS pump woul dhave taken 12 hours.
Works like a charm By LBK Reefer on 11/30/2015LBK Reefer would recommend this product to a friendI have a fairly large reef at +2,500 gallons and found this pump to work very well as a dosing pumping. It is working fine and does not have any issues self priming. I was expecting to spend some time trying to set the pump up and it was super easy and ready to go in a couple of minutes. I have ordered 2 more!
Does the job. By Sean on 10/22/2015Sean would recommend this product to a friendI've been using this top off pump for 2 months now and its working good.

Have a great day!
The BRS Top Off Doser can be mounted in any orientation. Upside down, sideways, or vertical it does not affect the pump or the mounting bracket. Depending on the position it is mounted in will dictate where the inlet and outlet tubes will be placed since they cannot be adjusted on the pump.
The electrical cord is 6 feet long.
