Hey everyone. I am wondering if I can get some of you to bring me samples of your tank waters and RO waters to Reef Ed. I will have a cooler inside or outside somewhere to collect the samples. I will post instructions as soon as I get some interest. Anyway, I am a chemist and am looking at captive reef water conditions. Trace elements and things like that. So any and all donations are gladly accepted. If you want data back you can write on the container and eventually I will work up all my findings and let you know what I found and how it compares to the other tanks in Denver. Healthy tanks only please! If you keep "expert" level species successfully in your tank, I would like to know. I cannot use water that has been used to transport fish, coral, or algae. So chime in guys so I can get a count. A pee cup full is fine.
