Is This Over Doing It?

The filtration seems fine...you can get away with a 50% weekly water change.

you need bigger filter!!! and more water changes.

You will need a bigger tank than the 55g or even the suggested 75g, unless you get rid of one of the flowerhorns.

Flowerhorns grow very fast and the two you have will soon outgrow even a 75g.
