Simple and effective By CalgaryGuy on 2/10/2014

The unit works great on the relay outlets on my Apex Energy Bar. I haven't measured the dosing but considering all the reviews saying it is perfect I see no need to.
Instructions are pretty thin but on the plus side they include a couple different kinds of tubing to suit your needs and there's only the quietest of whirring when the unit is working.

These things have changed the way I dose. No more hand dosing and, occasionally, forgetting to do so. I set my controller to dose at specified times, every day, and don't have to worry about a thing.

I've been using two of these pumps for a year now and haven't had one problem. Doses the exact dosage 6 times a day for me. I couldn't run my tank without two of these pumps.

I finally decided to automate this process. Works well with the Apex Controller - the actual drip rate varies between the two pumps - one is 1.2 ML and the other is about 1.35 ML. But they are very quite and seem to be working well
Great for what it does but they are not 1.1ml/min By Bob on 1/11/2014
Bob would recommend this product to a friend
Really like having the dosing pump. Very important to test ALL of the pumps you get to determine the REAL rate. I did a ten hour run with graduated cylinders for accuracy and I got 1.4583ml/min which is ~33% variance.

These dosers are awesome! Makes dosing 2 part easy. Pumps are reliable and super quiet. Put them on a timer and once you have your dosage dialed in, let the pumps do their job and never worry about manually dosing again. The price was the best I could find as well. Another great product from BRS

I use a number parastaltic pumps for work and are on par with the commercial grade pumps.

I bought two of those pump to set up 2 part dosing regime, but for now I was testing them on my quarantine tank as automated, continuous water change. I used Apex Controller to time them. They both have same flow rate, which I checked during calibration process.
After running for several days, I can say now that they pump same amount of liquid with good precision.
Great system By Joepat on 12/17/2013
Joepat would recommend this product to a friend
The system works great. I bought the whole system with everything needed and it works like a charm. No more dosing twice a day. The only reason for the four stars, the directions could have been a little better. "Use the white tube for the inlet and the clear tube for the outlet and use a standard 8oz. measuring cup and not the little cups that come with it".

Excellant Dosing Pump By BuckeyeFrags26 on 12/10/2013

I currently own two different types of dosing pumps, this pump in general out performs the other three that are by a different company. I would highly recommend this product to any hobbyist who is wanting accelerated growth or simple dosing needs. This pump handles any need one could have for introducing a substance or formula into your water column. Im currently using mine to dose my Frag Tank and couldn't be any happier with the output of this unit. A+++++++ FOR QUALITY AND PERFORMANCE!
BRS 2 Part Doser – 1.1 mL per minute By Selter904 on 12/8/2013
Selter904 would recommend this product to a friend
BRS 2 Part Doser – 1.1 mL per minute
This is a great product! The only reason I did not award it 5 stars is that it is advertised as 1.1ml per minute, when in fact after testing the amount dispensed within a 10 minute period. all three of the units I ordered dispensed 1.65 ml per minute. This much if a variance in advertised disbursement could cause someone to overdose over an extended period of time.
As long as you test calibrate this product, it will not let you down.

If you own an apex there is no reason to buy a third party doser....two of these and an eb8 makes a great doser. I have been using these on my DT for 2 years and they work great... Just bought 2 more and another eb8 or my frag system....

The pump is clean looking and I like the set up I made. The problem is my reef keeper is glitchy of you adjust the doses during the day It misses the rest of that days doses. I would recommend only testing once a week and adjusting just as often.

Good dosing pump. By Chad on 7/22/2013
Chad would recommend this product to a friend
I purchased this pump after watching the product demonstration video. I was a little bit concerned about how noisy it might be after hearing the caution about mounting it to your tank stand. This pump is extreemly quiet, but not silent. I can only hear it when I'm specifically listening for it to turn on.
If accuracy is EXTREEMLY important, make sure you calibrate it using the included instructions.
Time will tell if the pump remains quiet and reliable, but it appears to be of quality construction.

I 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.

Bluewaterbruce would recommend this product to a friend
I 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.

As 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.

Had this unit for about 3 weeks now. about 1 1/2 week ago, it overdose the soda ash solution. I set the pump to run 1.5 min for every 24. Unit sucked down almost a gallon of solution overnight. Thought I made a mistake in programming. So reset everything and tried again. Just came back and found the pump is leaking pass the pump. After the last assigned dose and pump stop, the liquid continue to leak into the tank. This time it dosed a 1/4 gallon before finding it. unit did not pinch the tube to stop the flow from continuing. No information on how to correct. No trouble shoot section or contact help.

jlemoine2 would recommend this product to a friend
I have two of these and use them for dosing 2-part calcium and alkalinity. Been using them about 18 months.
These are small enough to mount just about anywhere. I have them mounted in my tank stand and use an Apex controller to activate dosing at appropriate intervals. I use them on the mechanical switched outlets. I worry the digital outlets may not be able to detect the low power draw,
I gave 4 stars because the two units I have do not dose at the exact same rate... which leads me to believe they are not exactly 1.1 ml per minute. After the first couple of weeks of usage, I found I needed to run 1 pump about 3 minutes per day longer in order to dose my 2-part evenly. It's not such a big deal to me. I'm not sure if one of mine has something wrong with it, or if this is to be expected.... but I never bothered to call and complain about it.
