Very good work. Snipe I have discovered if one or two small tilapia are in the cage with the test fish, so far the tilapia have kept the cage clean. Maybe numerous tilapia outside the cage also help clean the cage.
Bill, I have 3000+/- Tilapia in another pond and that would likely be a good answer and I wish I would have thought of that. If nothing else it would have extended the time between clog-ups!
