Also you need to have something in the water to filter out. I would always feed a good amount a few hours before I would do a good sized
pwc. I used Hikari First Bites, fish fry food, there is also some newly available foods from Kens fish called Golden pearls, and the very fine size sounds like it would be great for them too. Crushed freed dried foods would work as wekk as crushed flakes, though I rarely use flakes as I feel they are big ammonia causers
You could also use Hikari Crab or Shrimp Cuisine crushed. I think setting up a good DW to perch on near the intake would be a great idea. Mine always love the out flow best cause the flow was strongest but that was the cleaner water.
