There is not. My first tank I did not understand sumps at all, baffles, all these different areas, and I just gutted it.
With the exception of the skimmer, it was perfect. I had to get a stand to raise the skimmer (because I removed the baffles!). Meh, lesson learned.
Now the only filtration I actively use is an algae turf scrubber from santa monica. I have filter socks and UV if needed, and the old skimmer is on the shelf in case of emergencies. But this new 220 gallon tanks sole nuetrient export is the ATS.
