Works as expected By Nicholas on 6/10/13Nicholas would recommend this product to a friendI already had a ATO doser of the same brand and really like the hardware.
I got two of these to run my 2-part dosing. I "calibrated" the two pumps at the same time and they were both dosing @ 1.3 mL / min. That made it easy to calculate my dosing schedule on my ReefKeeper.
These are great dosing pumps for the price.
Been running 12 months now By ReefDVMs on 4/21/13ReefDVMs would recommend this product to a friendThis review is of four of these pumps and they have been running for twelve months now with out issue on Ca Mg and Alk, great products BRS
Awesome pumps!!! By Steven on 4/5/13Steven would recommend this product to a friendThese pumps are awesome, always consistent flow rate and quiet. Very good quality.
Great products prices and service By Scottmo on 3/25/13Scottmo would recommend this product to a friendThe dosing pumps work great and if you haven't learned it yet, in this hobby buying low end products will always cost you more in the end. Go with BRS and you can't go wrong!
Great Pumps By Thomas on 3/19/13Thomas would recommend this product to a friendI have been using two of these pumps for four months now. I love them. Easy mounting and great documentation from BRS. I have them controlled by my Neptune controller. No easier way to go.
Quality Dosing pump By Bluewaterbruce on 3/3/13Bluewaterbruce would recommend this product to a friendI bought 2 for dosing alk. and Calcium, they work as expected. They dose great, I will recommend if you are trying to save a few bucks on a digital timer that you at least get a quality digital timer or upgrade to the apex or Neptune . I had a cheap ass timer from harbor freight go bad. I have a Home Depot timer on both now and haven't had any trouble. I just want to add that the timer sold by BRS looks identical as the one sold by Harbor Freight but maybe I just got a bad one.
A winner By migity1 on 2/10/13migity1 would recommend this product to a friendAs for my "2 cents".....
These pumps work as advertised. No problem with priming them (just turn them on). No "Back Siphoning"
I checked the output and both of mine dose 1.2ml/min,
pretty close to the claimed output! If your looking for a dosing pump, you can't go wrong with this one.
Great dosing pumps! By BK on 2/6/13BK would recommend this product to a friendFinally glad these came back in stock. Hard to find a better deal for a more reliable and reefer friendly product. I dose on the hour with my APEX controller for rock solid Ca and Alk readings.
Awesome pump By dstachio on 12/30/12dstachio would recommend this product to a friendGreat pump. Works well and was easy to setup and use with my controller. Be sure to use the mechanical relays with these pumps. They were a little larger then I expected but were easy to mount in my stand.
Great little pump By Scott on 12/27/12Scott would recommend this product to a friendI use these with my DA RKE controller to dose the BRS two part. Totally silent and very accurate. Highly recommended.

Which BRS dosing pumps? I have a 29g biocube I'm setting up with a spectrapure TO pump and want to go more toward SPS. I have an Apex controller to run the 2 part pumps but am not sure whether the 1.1ml or the 1.5ml would be more appropriate for my situation. Also what time is shipping cut off. what time do orders need to be placed to go out that same day?
Bulk Reef Supply Hey John,
Either would work fine as far as speed goes but the 1.1ml doser is a more robust doser, has nice compression fittings, and comes with a bracket. Its a better doser at a better price.
Shipping cut off is 3:30 CST for domestic orders. For orders shipped to Canada, anything in before 11:59pm Thursday will ship out Friday, anything after that will ship the next Friday.

What happens if the container runs dry - will the pump continue to run? - will this cause damage to the pump if it's allowed to run dry?
Bulk Reef Supply Hey Wayne,
The BRS dosers don't rely on solution for cooling/lubrication, etc. Its perfectly fine to run these pumps dry, wont make any difference at all whether they are pumping air or solution :-)
by Eric on February 12, 2013, @7:31 AM
What is the size of the pump. I need to install two of them inside the stand and the space is limited.
Bulk Reef Supply Hey Eric,
Great question. The dosers footprint is 5x4" and it is 4" tall.
by Dave on January 17, 2013, @5:26 PM
What are the dimensions of the doser?
Bulk Reef Supply Hey Dave,
They are about 5x4 and 4" tall.
by Ray on October 19, 2012, @10:13 PM
How many peristaltic pumps does this 2 part doser come with? one? two?
Just wanted a clarification...
Bulk Reef Supply Hey Ray,
This pump is a single doser. You would need one pump for each solution that you plan to dose!
