- Two Little Fishies Kalkwasser Stirrer/Reactor 300
Decent if you have small tank and small budget By Rob on 2/28/14Rob would recommend this product to a friendI bought this little reactor for my 55 bowfront thinking it would be great and I guess it is for the money. Setup is critical to good results.
A) Don't put too much kalk in. Keep kalk below the little spinny jet or it will get plugged.
B) Use a low flow pump to avoid stirring up too much kalk
C) Pray your check valve is functioning or it will back siphon into your top off container.
D) Make sure you place it as close to the same level as your top off container as possible.
E) Don't run it for more than a few seconds at a time or you will blow kalk into your tank. Top off more frequently (I use reefkeeper) A small pump really helps here too to keep you from over stirring.
You get what you pay for. By Quinnchero on 12/18/13Quinnchero would recommend this product to a friendHeading says it all. This is a very cheaply made product.....that actually works though. Like a few of the previous posters have stated you have a very short window of time before the truly saturated Kalkwasser water is pushed out and the Kalk itself is being sent into the system, which is NOT a good thing to happen.
Side note here: I searched for this information for quite some time on a large number of sites with no success: IT WILL NOT WORK WITH A LOW FLOW ATO SYSTEM ie. ToM Aqualifter pumps which many use for their slow ATO systems. You will need a minimum 200GPH pump.
Love it..works great on my 120 By Budman on 8/15/13Budman would recommend this product to a friendI use to drip kalk outta 1 gallon container and really got tired of making it every other day so 6 months ago go I got this unit and I'm so pleased with it,especially for the price.It keep my levels in check and probably fill it with new kalk every 2 weeks,Great unit for the price and would recommend to everyone..
great buy By Robert on 4/4/13Robert would recommend this product to a friendI think this much better than the motor driven reactor. Great Buy
You get what you pay for By MHG on 3/10/13MHG wouldn't recommend this product to a friendI bought this aver a year ago from BRS. At the time I liked it but I found it has a few issues.... It does a poor job at stirring the kalk as the days go on. It does fine when you first add kalk. It starts to solidify on the bottom and the stirrer needs maintenance often to keep it spinning... You only get about 50 seconds of pumping top off water through it before it starts blowing kalk into your tank. That is using a maxijet1200. It needs to run about once an hour to keep up with my 60 gallon tanks evaporation rate. But you can not run it more as the kalk needs time to settle. This is going to be an issue on bigger tanks...
I would imagine a motorized stirrer would get more efficient use but at the price you pay for this unit it is ok I guess. The one great feature is how easy it is to add kalk. Just make sure you do it right after the unit pumps so the new kalk has time to settle...
Life is easier By cdbstl76 on 3/4/13cdbstl76 would recommend this product to a friendI previously had a ATO set up. I also had a home-made drip system for my Kalwasser. Now, I have them combined! I didn't care much for the fact that due to it's size, mounting options are greatly limited! Pay attention to the height and depth needed for this product. I could not mount it where I had initially planned, due to poor planning. However, once a new solution was derived, I couldn't be happier. Now, every time my ATO kicks in, I get a little dose as well. I will have to keep an eye on my levels and may have to adjust accordingly due to amount of top off that enters my system daily. But, this is so much better than my previous delivery method!
Great deal but be careful adding more kalk By Gregory on 10/22/12Gregory would recommend this product to a friendThis thing is pretty sweet for the money. Simple yet effective solution that works well when you follow the directions and only add 1/2 cup of kalk at a time. For my tank, that lasts a couple of weeks since I have really low evaporation. Before adding another 1/2 cup of kalk to the reactor through the top, make sure you dump at least a half a cup of the effluent out into another container first, or you'll increase the effluent level in the reactor with the fresh kalk powder, and it'll start dosing out the kalk powder you just put in!! Talk about a pH spike...
Nice Reactor By Sean on 1/31/12Sean would recommend this product to a friendI was tired of mixing kalk manually in another container so I decided to give this a try. I figured for the price why not. I have to say I have been pleased. As long as you don't put too much kalk in it works perfectly.
Good for thre $$$ By Mark on 10/15/11Mark wouldn't recommend this product to a friendWell this is the first reactor I purchased (aside from the BRS GFO I purchased at the same time). It is built as one would expect for $65. Lots of thin lightweight plastic. That is not to say I am disappointed with it. I like its ease of set up. It is clean and easy to replenish the kalk. No water to mess with. Easy to install…
You only get about 1 minute of run time before the kalk dust is stirred up to the top. That means setting your ATO to top off many times a day to keep up with evaporation.
Still, I would recommend it as for the money it can’t be beat...

This reactor does not drip. So how many times should I turn it on and for how long should I let it pour in the sump on a daily routine.
Bulk Reef Supply Hi Dannie,
Its meant to be hooked up inline on your auto top off system. That way your auto top off just adds a little bit all day as water evaporates. If not using it that way, you want to use a very slow pump (like an aqualifter) and run it frequently for very short bursts (to avoid a spike in pH) as necessary to keep up with your calcium and alkalinity needs. Test your parameters over the coarse of a week and if they go down, you need to add a bit more and vice versa.
Two Little Fishies Kalkwasser Stirrer/Reactor has a patent-pending design by Julian Sprung. Uses upflow principle to achieve the most efficient use of Kalkwasser. By pushing top-off water upward through the calcium hydroxide, it automatically mixes it to achieve a supersaturated kalkwasser solution.
- Very convenient design that can be mounted hanging on the back of the aquarium or below the aquarium.
- Includes check valve and flexible connection fittings that rotate 180 degrees to allow a perfect custom fit to your installation.
- Threaded lid design makes adding calcium hydroxide or servicing quick and easy.
- Model 300 for aquariums up to 300 gallons.
- Height: 15.25"
- Width: 5"
- Reactor Diameter: 4"
- Inlet/Outlet: 1/2 inch
Inlet and outlet elbows allow for 180° rotation to suit your needs
