Kalk in my ATO is not performing as well as it once did and quite frankly I'm tired of the opaque slag in my sump. I have a really beautiful mint green chalice with pale pink eyes. Sorry I'm not familiar enough to know the variety. It very big and would make a great addition to a chalice collection. Text me for pics. 2534593665. I'm lookin to trade for a doser(s). Open to a self contained unit but truthfully lookin for simple types(BRS style) for use via my Apex.
