ok, someone else asked if the other media reactors would work with kalk. i didnt think that would work, so i came up with this idea based on the other media reactors. a small kalk reactor with a removable maxijet 600 for a stirring pump (included).

$120

this is the first one, and it is ready to go, if i need to make more, it will take a few days to get some maxijets from premium aquatic
