Howdy;

I'm about 3/4 of the way through the MACO course on building a calcium reactor, and I'm dying to get it up and running. It looks to be a very high quality reactor; 6" cast tube. Mine will hold a gallon of media; the smallest size the course offered. I'm learning all kinds of useful things about acrylic fabrication. The reactor will end up costing less than $150, including the price for the course. In addition, I'll have to buy an eheim pump and a CO2 set-up; about another $150. So, for $300, I'll have what I hope is a killer reactor, plus the knowledge (and templates) to make a high-end beckett skimmer. I highly recommend these courses.
