Hello I am Kirk a ex usnavy veteran in a nursing home in PR. I keep a aquarium for the enjoyment of the othe elderly veterans as well as myself. I have set um a new one in our occupational therapy room and hav had it running for about a month and a half some times I have questions about what is going on or things that I just don’t have any idea of what to do. Therefore I had a hope that someone out there would help me with my questions.
