kalk reactor

[phi delt reefer]

what are your levels in ur sps tank. if something else is off kalk wont help.

though the diy kalk stirrer kit from avast looks pretty good. AT $150 its tough to beat and if it ever breaks you know how to fix it, LOL

Or simply set up a drip or add some kalk to your ATO. Much cheaper and nothing to break down.
