Well, keeping fish for many years now, I have tried many different kind of filters. I have made my own DIY filters which did an excellent job. But this all changed when I had got a lot more tanks for breeding purpose. I found myself in a situation where I could not setup filters in all my aquariums. So I just got some air pump, tubes and threw in simple air stones in each of those tanks and stuck with the basic bi or tri weekly water changes. During water changes, I did not much care about the dirt at the bottom. I just used a mug to remove the bad water from the top and then added fresh water. I wasn't really looking for beauty as those were breeding tanks and raising tanks.

When I do water changes, I leave the dirt at the bottom and only siphon out the water from the top area. I know that this is the opposite to what most fish keepers do, but I believe there is a lot of beneficial stuff present in the dirt to let go of. As a compensation for leaving the dirt intact, I do heavier water changes.
So, the whole thing here is dirt and simplicity. Fry love to dig into mess for food as compared to a filter induced barren desert, where food is only provided at a specific time. Fry need to have food 24/7 for best growth. They also appreciate aeration. So in short, if you are raising fry, avoid any type of filter, do water changes leaving the bottom dirt, feed powdered food and watch them grow. I even have a discus baby that growing rapidly in this setup.
