tlp,
could you shed some more light on the details of your DIY kalk reactor?
What is the bucket to the left for?
Does the par. pump pump water through the bucket continuously?
What is the pump being fed by? Your RO unit?
Are you using any kind of mixer in the bucket or are you mixing by hand?
You mention that any additional make up water is handled by the computer. Does it flow through the kalk reactor or dump straight into the sump?
Sorry for so many questions. Im just interested in maybe building one myself and would like to know if you basically copied a commercially built acrylic reactor or made up your own design. Any details on how the path the water takes from start to finish and how much you have to play with it would be greatly appreciated.
The reactor is just one of the bucket. I have a float valve in there to control RO water addition ensuring the bucket is always full.
A maxijet powerhead is suspended from the lid with some strings, to about 3" from the bottom, with the nozzle pointing down. This pump is on a timer, ON for about 10mins every 6 hrs or so, to stir the content.
A peristaltic pump takes water from 6-10" ish from the top of the surface and drip into the sump continuously, except for when the mixing pump above is on, when it stops for about an hour to allow the solution to settle down.
Periodically I would just throw in a cup full of kalk powder to top it up. That's it essentially. If I was flash I would add a conductivity probe to ensure that the solution was saturated to allow dosing at optimum level.
A float valve in my sump calls for additional top up (via the IKS computer) when the dosing rate above doesnt' meet the evaporation demand, in which case another small powerhead (throttled back) add in additional RO (or kalkwasser depending on calcium demand of your tank).
The second bucket is just my 'spare' RO container for miscellanous use. When I was making my own phyto this bucket hold the pre-mixed solution for phyto production, with it's content being passed through a UV unit constantly to ensure sterilisation.
