I was turning off the skimmer and main pump, and leaving the chiller pump on. I don't have any internal circ pumps. However, it seems with very little flow in the tank, the food just hangs in the water column.
If I turn the main pump on, a lot of it gets whipped up to the surface and pulled into the skimmer box, which I assume then gets caught in either my filter pad or the foam filter.
I'm considering pulling out the filter pad, removing the foam sponge, turning off the skimmer, and leaving the main pumps on when I feed. It's only a few times a week. My thought is that it will keep circulating the food around the tank without getting caught in the filtration process.
