I can't stand hearing him demonize kalk with zero evidence to back it up.
I believe FM sell kalk:
I am not sure they are demonizing it.
The issues FM stated in the past:
1) kalk when dosed has precipitation and that this precipitation can accumulate over time. At least something to that effect. If I recall all high pH additives suffer from precipitation, I had it bad with hydroxide so I gave up on it. Had to clean my pump monthly, while dosing bicarbonate I clean them once a year.
2) The ratio in kalk leans on calcium side. Correction may be required.
3) when dosed from ATO you can end up with inconsistent doses/ instabilities .
I believe all have been mentioned on R2R so…
From my experience I tried kalk and I did not like the mixing etc…
Also mixing bicarbonate seems safer, playing with liquid that is 7-8pH vs. 10+ pH with kids and pets at home seems safer. But that is my opinion only. I take full responsibility for any incorrect information in the last statement.
When I have time I will need to watch this episode.
What entertaining week…
