I have a Fluval 13.5 gallon tank. It’s been running for 1 months now. I have a clown fish, peppermint shrimp and turbo snail. My levels are always 0-0.25 ammonia nitrite 0 and nitrates are 20ppm. I wanted to start adding Zoanthids and other hardy things to my tank over time (very slowly not rushed). I read that in order to keep them my tank needs to be at zero nitrates. I know good husbandry and don’t over feed and all that keeps nitrates down along with water changes. With my tank being newer as it matures will it cycle out nitrates at faster rates giving me the desired number of zero so that I can have and maintain some hardy corals or should I be looking to add something to my filtration set up that will help. This is my current set up. First chamber pump and heater. 2nd filter block and 3rd is the skimmer with some small pieces of dry rock. Under the 2nd chamber and 3 I have space for something. Thanks for any input or ideas.
