Sponge filter and use the bulkheads for water changes.
You can set up a whole system to drain and fill

They are really good and easyI'm going to be opening a pet store . So I will have all kinds of fish . Are sponge filters really that good . Could they really keep a tank clean?
Totally agree here. If you have new fish coming in constantly, that opens you up to disease and loss.Just a thought, if you are opening a pet store then you might want to have multiple systems because you can avoid all of them getting infected at once. I would think that it would be pretty devastating to have all of the tanks infected at the same time.
