You know what's kinda cool about you Doug ,... You're just one of us,,...you go thru a lot of the same issues as the rest of us and you're not afraid to tell us about your successes and failures too,...it's kind of refreshing to me and I'm sure to others here ,that although you're very,very knowledgable in this whole field of saltwater aquariums.., you occasionally lose some corals , get some Cyanobacteria or maybe buy something you wish you hadn't ,...I guess we all kinda try and learn from others mistakes and successes,...I sure have!! ,..anyway thanks for always being available for some friendly advice ..,and in case no one else dares to say it,...I for one am very glad you're here !! Thank you ,Dary
