Trying to decide on which to buy. The units are very similar. They are both stirrer operated, not pump. From what I can tell, there are 2 main differences. First is price. The Avast marine is vastly cheaper at $180 compared to about $500 for the aquamedic. The second is that the aquamedic is completely sealed and can be under pressure which means I can place it practically anywhere and there will be the least possible exposure to air. For some reason I like the idea of the unit being completely sealed but I'm not sure that its worth $320.
One important thing for me is how long in-between kalk changes I can go. The aquamedic is reported to hold 600g (4.5cups) and I emailed avast and he said the K2 can hold a max of 8 cups. So it looks like Avast wins there too, unless air exposure limits refill length.
Can anyone comment on the Avast marine product and how much air exposure there is (do you feel the kalk goes bad faster because its not completely sealed)? How does the lid sit on the unit? does it just sit there or is there at least an O ring or something to prevent it from turning when the motor is stirring?
