Great Stirrer By Justin on 11/17/12
Justin would recommend this product to a friendI've had this Kalk reactor running on my tank for more than a year and a half. The only problem with it that I've had was the stirrer cracked where the screw attaches it to the motor at the top. I had to buy a new stirrer. Other than that it's been great. -
Good product By paul on 7/20/12
paul would recommend this product to a friendI have had this product for about 2 years. I love having it and find it a great way to add Kalk to your tank. It works really well although it has jammed up a few times and I had to force the shaft to get it to start turning, also I have had it squeak from time to time for extended periods, not too loud. I am using it with a Tunze Osmolator and it does a great job. you have to be careful though. If you have a small water leak or if you start doing a water change before you unplug the Ozmolator it will put concentrated kalk into you tank really fast. A controller would probably negate that possibility. All and all I would recommend it. -
Good product...a little pricey By Bob on 5/15/12
Bob would recommend this product to a friendThe product works as described and doses the kalk as needed with the top off system. It seems to be a little expensive for the materials used but it works. -
Good product By Frank on 2/1/12
Frank would recommend this product to a friendIt works well but a little over priced for what it is. I have been running this stirrer for 3 months and it has worked well for dosing Kalk to my 90 gallon aquarium. I plan on buying another soon for my next build. -
Very good for the price, comparing to others. By A. Grandis on 1/31/12
A. Grandis would recommend this product to a friendThis a very good kalk stirrer! It works great to keep alk and Ca++ to any marine system.
I use it with a BRS 5ml/min. pump/electronic timer dosing 4 times at night and it does the job greatly. Each time the pump doses for 15 min. The tank is a 75gal with a 20gal. sump. Coralline is all over the tank after only 20 days of added the reactor. No other calcium or alk. supplementation is added since then. Simply set and leave it alone doing it's job. Once an a while I check the pump and watch it work.
The only thing they could use better materials to build it. The idea and the dimensions are really functional, but the materials they built the reactor with are not the top quality. They could do a better job!
The check valve was installed in the opposite position and I'm glad I removed to check that out!!!!! That IS a BIG mistake when assembling the instrument!!! Shame on them! Hope it doesn't happen all the time!! A newbie wouldn't be able to figure out why the reactor wasn't working. Pump was pushing the water in and the reactor couldn't let the water flow to the system because of the check valve!! Crazy mistake!!
BUT...
I will buy another of this for my future system!!!
I think this is the best for the buck for now in the market. I'm glad I've bought from BulkReefSupply!
Cheers. -
recent purchase By denis on 11/24/11
denis would recommend this product to a friendi just purchased the 1000 and its been a weeek and all my parameters have been perfect alk, calcium and magnesium, you have to have your parameters up to use a kalk reactor -
Great Kalk reactor By Larry on 3/14/11
Larry would recommend this product to a friendI used to drip Kalk into my sump but, it was a hassle to mix the kalk, siphon into a drip container then adjust the drip rate every few days. Then I tried dosing Kalk in my ATO container, but that was just a mess and hard on your ATO pump. With the Aquamedic Kalk stirrer ... pretty much set and forget. I use it with my Tunze Osmolator and it works great! This is the easiest way to dose Kalk out there. -
good product By Erick on 12/3/10
Erick would recommend this product to a friendi am using with RO top off. simple to use. not as solid as some other stirrers but not as expensive either -
Love it By Corey on 12/2/10
Corey would recommend this product to a friendVery easy to set up and maintain. For me a prefect way to counter my low PH caused by my Ca reactor. -
Works well but matierials are bit cheap By Clown Boy on 11/21/10
Clown Boy would recommend this product to a friendThe Good; The product works exactly as advertised. The genital stirring action keeps the top few inches of the water column fairly clear thus the affluent is clear when exiting the reaction chamber. A word of caution, kalk is dripped not drizzled into a tank. If you use anything other than a peristaltic pump (per directions) you run the risk of over dousing.
The Bad: The construction materials are cheap. For $230.00 I expected more than low grade molded plastic. I believe that the width of the base is disproportional to the height / width of the chamber considering that if the reactor falls over you have a serious mess on your hands. The reaction chamber is made of rather thin plastic and on my reactor the joints between the chamber, cap and base are all a bit sloppy. I suppose that for the money I was thinking acrylic and quality craftsmanship. Once I filled the reactor it leaked - everything needed to be tightened up. The back siphon fitting was placed inline backwards and the directions that came in the box were for the 5000 model - really - for $230.00? For a few bucks more a very solid Precision Marine or GEO reactor can be had.

Great stirrer for the money By Ray on 3/1/10
Ray would recommend this product to a friendAfter looking into the available commercial options for kalkwassers, I decided on the Aquamedic 1000. I bought it around 3 years ago (not from BRS unfortunately) for use with my Tunze Omolator. I found that the Tunze Ozmo supply pump was a bit too aggressive and caused excessive kalk clouding and switched over to an aqualifter. The 1000 itself functions as expected. Mine has been running/stirring nonstop for 3+ years and the only problem I’ve had so far is the stirrer motor has gone from relatively silent to a dull hum. I also had one of the plastic reducer bushings crack and leak after several years. This part was easily replaced with a quick trip to the hardware store. The top (motor and o-ring seal) has a twist lock for easy removal to add more kalk powder. One other useful feature is a built it check valve to prevent back siphoning kalk solution into your RO water storage tank. Overall I would highly recommend this product.

I am trying to tell by the Pics here, but what is used to stir the Arm?
Do i hook it up to a Pump or is it an Electric Arm and is the only Inlet for Fresh RO/DI and then outlet for Kalk+ RO/DI?
ThanxBulk Reef Supply Hey Paul,
Great question. There is a small motor mounted in the top of the reactor that slowly spins the arm. You pump in freshwater with a small pump like a dosing pump attached to your ATO. It pumps the freshwater in which will push out the kalkwasser to the tank.
Aqua Medic Kalkwasser Stirrers feature a bar that slowly spins continuously to keep the kalkwasser saturated at the right level. At slow flow rates it does not create the heavy kalk slurry common with competing brands. This simple feature eliminates much of the overdose risk.
Many of the other kalkwasser reactors available use a mixing pump to vigorously mix the kalkwasser at periodic junctions. This creates a highly-concentrated slurry of kalkwasser that cannot be dosed until it has settled out. To protect against this danger, these types of reactors require a complicated series of timers to control pump operation.
