I made a drip doser like this and experimented for quite a while. I was attempting to do a continuous drip 24/7, but I could never get the drip rate to be consistent or accurate enough. No matter what I did, I would either drip too much, or the drip would stop. My Ca
went too high, too low...aaarghh!
My conclusion was that I could only make it work by controlling the total amount dripped every day. That is, figure out how much Kalk
I need every 24 hours and put only that much in the bottle...then drip away. The tank would get 24 hours worth of Kalk
less than 24 hours. Even this caused me to have to be adjusting the amount all the time because I couldn't be consistent enough to redo the Kalk
after exactly 24 hour intervals.
What I wanted was a Kalk
system that I wouldn't have to deal with on a daily basis and that could be controlled accurately.
...so I ended up purchasing one of those medical dosing pumps ($80). It injects Kalk
(saturated) at exactly 22ml/hr. This holds my Ca
dead level. Two gallons of mixed Kalk
lets me not worry about anything for 2 weeks.
I really recommend using a dosing pump....but like everything else, it costs extra.
