Great pumps - don't forget to measure output By Joseph B on 8/17/2015
Joseph B would recommend this product to a friend
I bought two these pumps to add macro and micro nutrients to my freshwater planted amazon bio-type system consisting of 200 gallons. I bought these pumps on the recommendation of another freshwater aquarist and was hoping they would deliver a bit more than the BRS two roller pumps. I did not expect them to be spot on at 1.6 ml/min but was a bit disappointed that one is 1.3 and the other is 1.2 ml/min. Great pumps I just have adjust running time and concentration to do what I need to do.
Dosing made easy By hans on 10/17/2013

I have 2 of these for calcium and alk. I have them hooked up to my Apex controller and it makes dosing easy. Much more consistent way of dosing compared to hand dosing. Set and forget. Make sure to check Ml per minute, mine were a little under what it was rated. Other than that no complaints here

I use two drew dosers to maintain my levels with 2 part. Working well and only time will tell but so far so good.

Bought two of these and so happy I did. No guessing pretty much just set
and forget. Adjustments will need to be made over time as corals continue to grow and demand increases, but what a pleasure to know the tank is being dosed the exact amount everyday !! Sorry I waited so long !!
Best Dosing Pump I Have By Peter on 5/6/2013
Peter would recommend this product to a friend
I would highly recommend the Drew's dosing pump. The tubes are better with the BRS dosing pump which I have two of, but this is a much better pump in my opinion. I use this for the calcium portion of my dosing. If I was doing it over I would buy this pump for all of my dosing pumps.

At first I wasn't going to spend the extra for these pumps but now that they are up and running, I'm glad that I did. Great pumps. Spend a little more for these pumps and don't worry about if you made the right decision or not.
Short cords By MAtt on 6/2/2012

The cords could be a bit longer. Its much better to wire tie than to try to stretch a cord! Otherwise they seem ok, but too new to tell.

I've used the Drew's Doser for over 2 years. I use it to dose Soda Ash daily in my 120g sps dominated reef display tank. It's been very reliable and is easy to operate.
just installed great doser By reefez on 3/11/2012

I just installed two of these dosers very easy to do W/reefkeeper lite only down side for me is that both dosers had different out puts .So a little timer management and I am good to go. Very happy with my choice so far.
Makes life much easier. By Kevin on 9/27/2011
Kevin would recommend this product to a friend
Bought two of these along with the Eco Plus Dual digital timers here to set up my 2 part dosing system. The pumps work quietly and accurately. The corals in my tank look so much better now that Calc/Alk levels are stable. Due to the initial up front cost, I was a bit hesitant to set up this system. Using the bulk supplements however saves alot of money long term. (Compare a bottle of prepared liquid Ca at $12-15ea to the 7lbs of powdered for the same price which makes 8 gal. of prepared liquid Ca.) The pumps feel solid and run smooth and quite.
great little pump for dosing By mjd on 7/4/2011

Switched to these pumps after having troubles with the BRS dosers (read review there), and have never been happier! These are consistent, nearly silent, and haven't let me down in over 18 months of dosing. I am going to get a third to dose magnesium along with the 2 part!

I bought two of these to go with the BRS 2 part system. After hooking them both up to a timer they have maintained my levels well and taken the daily chore of calcium dosing away. Exactly what I was looking for.
Very quiet By Calvin on 2/1/2011

I got this doser because the BRS dosers were out of stock, it is quiet and consistent but I prefer the hose connections on the BRS doser.

STEVEN would recommend this product to a friend
I held off on getting dosing pumps because of the cost and what I thought was complexity of setting them up. After researching and finally pulling the trigger I realized I was wrong on both of my concerns. I bought three of these pumps and had them mounted and programmed with my Apex controller within an hour. No more manual dosing and I love it!!!!! These pumps are sturdy and well made!
Great value, but check it before installing By Cmor1701d on 11/21/2010

I ordered two of these for my 2 part dosing (Alk and Ca) because the BRS dosers were out of stock. They came well packaged with everything you need (including the plastic ties). The instructions are clearly written, but I found that one pump was spinning backward of what the instructions state after I attached my cut tubing. So I removed the plastic cover, reversed the hose and re-attached.
One is putting out 1.5 ml/minute the other 1.8. Instead of using my dual outlet timer for both, I guess I need a second timer for accuracy.
These pumps are dead silent, easy to set up and work flawlessly once set up.
using with kalk reactor By Mike on 8/14/2010

I use the BRS Dosing pump with a PM kalk reactor. it is quiet, low price and easy to install. thinking about replacing my calcium reactor with 2 part dosing.

Two part dosing 101. First get a Drew's Doser from BRS. I have two of them. One is dosing alkalinity with my controller spreading the doses evenly throuout the day and the other is dosing limewater at night for ph control. No more spikes or swings for me. I couldn't do without these they are perfect for my tank.
Awesome doser By John Hache on 4/15/2010

I have three of these, they are wonderful. No siphoning, reliable, great for daily dosing. They are quite and I cant hear them running.
I was mostly concerned that they would not perform consistently and that they would siphon. I can say that after months of use they have been reliable and consistent without an ounce of siphoning in either direction.

This unit is very simple and require extra timer to operate. Initial setup requires some timing/measuring, but once all done unit produces consistent results. I have two for 2 part dosing and both work very well. Very worth $$$.

I bought two of these for dosing 2-Part. They were a breeze to set up and work like a charm. They don't make a sound and are very accurate. I just plugged them into my aqua controller, programmed them and never looked back.

Using a pair of these for my two-part. Also have a pair of the "other" pumps offered here when these were out of stock. These are fantastic and hands down I prefer these. Get them when you see them because they seem to go fast.
