I started dosing kalk a few weeks ago (again, thank you Rob for the video podcast - wouldn't have made the DIY kalk w/o the video.) Ever since i started dosing Kalk, alot has been happening in my tank - all positive changes. I'm really excited about my tank now but laziness is making me think about buying or making a neilson reactor.. So heres a WTB post for a neilson reactor. Please PM me if you make them and/or are selling one.

i can make you 1 check this page calcium reactors (http://marinedesignsystems.com/calreactors.aspx) i am working on the page i wil show you a pic of a nelson reactor like the deltecs but not so spencive

I can confirm that Manny does great work.
