Boy am I late
let's hope that Boomer will reply.......is he dead or what
Also I have read that kalwasser can help the skimmer be more efficient because of (saponification),
Yes , if and only if it reacts with the kalk which \can and will happen to some degree. Rememberr kalk falls apart very fast in water to Ca++ and OH-
I was not meaning into the skimmer but as close to the skimmer as possible is it more advantageous or irrelevant ?
No not in the skimmer. My guess somewhere near the skimmer, where the flow is moderate. You would not want the flow to fast or dead. It needs time to react. To low a flow and the pH will get to high. To fast and you loose the time factor to react.
I do not have a clue what that would be. Each tank would be different.
It would be an intestesting article for Randy to do.
