I have some questions regarding my nitrate levels in my 55g reef. I've had it up since earlier this year so it's not very mature yet. I have been getting readings of trates at 2.5 every single time I test for the last couple months.
I understand this is a good thing pretty much but I can't understand the how. I now have 17 corals and as for fish I have 4 clowns, lawnmower blenny, spotted watchman, gramma, sea hare, 4 peppemints, a pistol shrimp and an extremely large population of hermits and snails. I mean like 100 of them total. I also feed at least 2 times a day sometimes three.
How is it possible to have such low nitrates in my case? My other tanks run much higher than that with much less bioload and feeding.
I know this might seem like a silly question to some people but it has been on my mind for the last month.
Any input? And while I'm at it what do you think it will take to get to 0? I used to do a weekly pwc
of 10g but I've switched to bi weekly 10g changes and still the same results.
