Whoa. That's some pretty heavy filtration for such a small tank. I keep no more than an AC
50 in my 30 G tanks and that's plenty if you change out half the tank water every week.
You know, a lot of tank keepers over filter their tanks. I never do because I remove and replace at least half the tank water every week. So, there no time for pollutants to build up before the next large change and the filters are just filtering water that's already pure.
The same water change routine means you don't need to use chemical filtration (carbon), because changing out so much water does a lot more for the stability of the tank than carbon does.
Do your large, weekly water changes and you don't need to over filter, use carbon media or even test the tank water, because you'll know the water conditions for your fish and plants is always stable.
