Hello:
Currently running a 5+ year old 135g mixed reef display with a 100g rubbermaid sump (about 50-60g actual water volume). Bottomed out nitrates and phosphates - these guys appeared along with what I believe to be derbesia sp.
Pics 1 and 2: Look like Ostreopsis to me - can anyone else confirm? If so, any other treatment besides UV? (trying not to break the bank if I don't have to).
Pics 3 and 4: Gathered a mat of 'algae' - not sure what to make of this mess...?
Appreciate the help!
