Hi,

I would have the two following questions regarding my KS100 Kalk reactor:
- The lodicules on my reactor are sticked together at the bottom of the shaft instead of having 1-2 inches between it. Is this normal? should I try to move the lodicules so they are aprat?
- I use an aqualifter pump to dose kalkwasser through the reactor. It always clog after a week. From I understand, it clog right after the inlet or in the outlet tubing. Do you have any advice to avoid this? I use a check valve before the reactor, could this be the issue? If yes, could you recommend a better setup / feeding pump to use? Because it always clog, I cannot dose kalk on a consistent basis and it becomes very unrealiable method to maintain stable parameter.

Thank you

1. They should not. If they are you need to move one up.
2. How often are you dosing? If you are only dosing once a day, it may dry up. I would recommend split the total daily dosage into more often dosages. Also, make sure that when you dose, the kalk has settled and only water is distributed. If you have any kalk dust with the water, then it will clog up the line quicker.

Thank you for your quick reply.

1. Ok I will try to do this
2. I dose about 30ml of water every 12 minutes throughout the day. The pump I use gets me a flow rate of 1.2 gal/h. Could it be too slow and it allows the powder to clog at the bottom? How thick of powder should I have at the bottom?

Thanks

The output is at the top. You want the powder to settle at the bottom and just leave a slightly white water at the top. That is the water that you want to be distributed to your tank. If you are distributing white milk-like water, then the kalk has not settled completely and that will clog up your lines much faster than if you were just dosing kalk water only.

No I usually don't dose the Kalkwasser right after mixing and I usually wait for it to have settled pretty much. What I meant is that the reactor clogged in the output but also in the intput at the bottom. This is why I was asking for the feed pump recommended flowrate. I was wondering if the flow rate was too slow. Could it be not enough to disturb all the undissolved Kalk at the bottom and this is why it is clogging?

Either that or you are adding too much kalk beyond the point of saturation. If you add to much, then it will just accumulate at the bottom and clog everything up without adding any additional benefit to the tank.

Could you please recommend the optimal quantity of powder I should use and could you please recommend a type of feed pump / minimum flow rate?

Thank you

If you are using a feed pump like Tom’s Aqualifter then the input tubing should be placed in your reservoir with RO/DI water. Connect the outlet of the pump to a short piece of 1/4” tubing and install a tee fitting with one end securely mounted several feet above the water level of your top off reservoir and the other going to the reactor. The tee is placed in the line to create a siphon break. You may also use a small pump such as a maxijet modded with a fitting on the output to feed water to the reactor. You will have to use a check valve in the line to prevent any back siphoning into your reservoir.

The Kalkwasser reactor should be filled 2/3 of the way with RO/DI water.

Add enough kalk powder to fill the reactor with approximately 3⁄4 – 1cup of kalkwasser. The idea is that the twin blades create a slow motion that gently disturbs the kalk in to solution. (Too much kalk will place stress on the motor and can cause pre-mature failure) Allow the solution to settle for 15 minutes prior to turning the reactor on. Now you are ready to plug the reactor’s transformer into a power source and begin to dose saturated Kalkwasser to your aquarium. The stirrer should be set on a controller to run ever 2 hours for approximately 10-15 minutes. Do not run unit 24/7.
