I was thinking of using my Duetto DJ 100, but it does 90GPH which may be too strong for a 5 gallon bucket. I have a 10 gallon glass tank with a cover, and my mom said she'll think about letting me set that up. The last splotches he developed showed up about four or five days ago. It doesn't look like he's getting better, but he doesn't seem to be getting any worse at the moment. He is staying in his burrow now during the day and he is more calm, so that seems like a good sign. I'm feeding him two or three times per day with Rod's Original Blends enhanced with 1/3 or 1/2 the recommended dose of Selcon (since I feed him two/three times per day, it adds up to the recommended dose) and I put two drops of Garlic Xtreme in his food. His tummy fattened after I fed him. I have the top of the tank covered in three layers of mesh netting which greatly reduced the amount of light getting into the tank. I'm going to try to do a 5% WC before the lights go out on the tank every day until I move him into the Q bucket.
