Hello. It has been many many years since I have visited but found this piece of equipment in my garage along with some other reef-related stuff and would like to know what it is. I can't really remember but I'm pretty sure it has something to do with directing water flow. Please identify if you can and tell me if it has any value. It will be for sale.
Thanks in advance.
