I've finally decided to bite the bullet on an alkalinity controller, only to discover there are several more on the market than there were last time I looked (hooray for competition!), and they're all available. I was surprised to see some bad reviews on the restocked Alkatronic, which is what I was planning on going for, so that got me wondering...what are you fine reef keepers using for alkalinity control these days? Do you like your alkalinity controller?
