Rob,
Welcome to RF :welcome:
You will find people very friendly and knowledgeable..oh, and we like pics
Can u tell us alittle more about your tank?
how long has it be up and running?
what type of equipment are you using?
what are your water parameters (ammonia, nitrite, nitrates, calcium, magnesium, alk, temp, pH, salinity) ?
if you are new to the hobby, I highly recommend you getting and reading the following book by Robert Fenner:

The link I posted is version 2, I have version 1 and even though I have almost 15yrs in the hobby, I found myself using it last night for research to some new fish I want to add to my 36g bow tank that I just set up in my office.
Don't be afraid to ask questions, as you will always find someone to chime in with an answer.
again, welcome.
