Big fish, high nitrates?
I made the mistake of buying a sailfin tang and putting him in 30 gallon tank tied to a 10 gallon refugium. He started off at two inches, he's now four. I think he's the reason I can't get my nitrates to go down below 40 ppm. Even after a 20 gallon water change, the levels went back up in less than a week. Could the fish be the culprit? (I do plan on donating him to my LFS, once I take my rock work down to catch him.
 )

Well, as much food as that fish is probably eating, I am not surprised at the nitrate level.

Thanks, bertoni. Yes, he eats and poops like a pig. A waste producing machine, but he's healthy. I managed to catch him without destroying my rock work, and my LFS has a nice big tank to let him roam free. (My purple firefish already knows the monster's gone and has stopped hiding behind the leather corals.)

I'm glad he was easy to catch.
He'll be easier to manage in a larger system.
