Well ... I went to buy a ReefBot, and it took me to some separate payment site, and my Bank wanted nothing to do with that. Must be a sign from above. Mindstream is still for sale, and sounds really great. But as near as I can tell, none have been delivered. Neptune Trident still seems hopelessly back ordered. I guess there is the GHL KH director. In stock. But that is really expensive, and only tests Alk, which may explain why it is not sold out. --- OR --- I can simply do like I do currently - Have the liquid tests still sitting on the side of my sump, as I procrastinate yet again about testing "next week." Not testing = Zero effort and Zero cost.
