Q. My name is Zach and I am 12 years old. I am currently running a 20 gallon reef aquarium, and have been doing a lot of research on this topic. Very soon I will be switching to a 46 gallon tank, and I have run into a big problem. I have been to many different fish stores in my area, and I have seen their beautiful reef aquariums. I ask them each the same question, and I have never gotten the same answer twice.
Some people say yes and some people say no.
I am stumped. I really don't know what to do. Please help me. Well Zach, both comments are correct, to some extent. Trickle filters with biomedia will produce nitrates, they are supposed to.
