Your thought about moving the water insprired me to go out and by a new filter. I oversized it, got a Hagen 150 which is good for a 30 gallon tank, I have a 20. I am going to move the baby pen in front of the flow when its feeding time. and out of the flow during other time. I bought some bio stones which is basically pouris ceramic and added that to the power filter for the bacteria to grow also. Doing this allows about 30% more bacterial/bio filtration on top of what the gravel bacteria provides. I bought 2 baby catfish to eat up the small debree from the feed training pen. There just baby cory catfish, figured the smaller the better. This should get interesting because the larva bass are eating, there is no doubt. The second hurtle... now to see if they start growing and the water quality stays good.
