Q regarding Kalwasser reactor

[Foreverlearnin]

Hi Roger,

I managed to get the 7400 Turbelle/singler controller, 230 skimmer, Osmolator and Kalwasser reactor up and running. I am very happy with everything, but I have one concern regarding the kalkwasser reactor.

I know when you make limewater you should only use the pure clear water, never any of the solids. When the osmolator pumps water into the reactor, it stirs the settled powder. I actually stirs it well enough that you can see small white particles floating up the body of the reactor in a pretty decent density. I suppose then that these small solids are being sent into my sump, then into the tank. I have not noticed anything negative yet, but just started using this reactor a couple weeks ago.

Is something wrong with the uiti or does it's intended operation include shooting the bits of solids into the sump?

Thanks for your time!

It may have too much powder. In my experience with 3-4 teaspoons of powder it only does this on the very first operation which is not going to cause any harm. It should also be delivered up to the aquarium, not the sump. Keep in mind most sumps are below the height of a reservoir so the reservoir will just siphon into the sump after the pump stops. I would also check that the hose is looped properly and the powder isn't back siphoning into the reservoir.

Thanks Roger

It does this with two or 4 teaspoons of Kalkwasser. It does it with both Calcium hydroxide or Calcium oxide.

As far as delivering to the aquarium, it's not a good idea in my case. Firstly as the sensor is in the sump, and the delivery in the tank, there is a lag in time and the system over delivers.

Hoses are looped properly.

What would you recomend as far as how much power(voltage) to supply the pump?

 

[rvitko]

The sensors are supposed to be in the sump, but the hose should always go to the tank unless the reservoir is below the sump, then you can make an exception. Since you are not pumping very high- but please double check this install, 9V will work.

There is no chance of back siphoning. How does this effect the amount of powder being shot into the tank?

 

[rvitko]

Lowering the voltage lowers flow. As for the set up, it is designed to pump up roughly 5ft to a tank, that is what all the illustrations show and that was what it was designed around, this would reduce flow and thus limit the amount of powder going into the tank.
