DIY kalkreactor questions....

Hi guys,

I've been reading about DIY Neilson kalkreactors hooked up to auto-top ups, what I don't understand, and what most of the websites i've seen fail to explain, is:

1. Where exactly does the water come in? (top or bottom of chamber)

2. Is the stirrer turned on 24hrs a day?

3. If not, how do you make sure that when the stirrier is turned on, the dosing pump isn't turned on?

4. Which direction is the pump pumping?

5. How to make sure that the soln in the chamber does not siphon back to the auto top-up reservoir?

I've included a simple diagram, please see if I'm correct in my assumptions...

Thanks!

Ervine

The design looks good. You should leave at least an hour for the undissolved kalkwasser to settle before the solution gets added into the tank to prevent undissolved calcium hydroxide from entering the tank too.

You can leave the stirring pump on manual control, turning it on only when you add more kalkwasser or once every 3 days, during which you can switch off the dosing pump.

Oh! so I don't need to keep stirring the kalk? Once in 3 days is enough?

Also, if the water in is at too high a pressure, would it cause the kalk settled at the bottom to stir up too much?

And, how to make sure that the water from the mixing chamber does not reverse can go back into the water reservoir?
