Sexy Shrimp: How High Is High No3?

[Caine]

Thanks for the replies. I don't think there is any uneaten food because I feed the little chunk right into the frogspawn mouth. I'm doing about 50% water change once a week. Would you suggest two 50% changes a week or one big paired with a couple smaller ones to bring those nitrates down? Its only about 4 gallons total water so it doesn't take much to do a small water change. I'll feed a smaller chunk of shrimp to see if that helps too.
