Congrats! One that I maintain stayed at zero until I switched filtration, came up to about 0.5 for a little while then right back down. What was your trick? Mine was a well established tank to start with, and tons of LR.
well when i was justing doing weekly wc its stayed between 5 and 10 then i added a skimmer, that was when it dropped to zero but im over skimming(rated for 50-85 gallon skimmer on my ten)
That's pretty awesome! My 120 gal is sitting at about 5 ppm in nitrates. It has been creeping down since I started running the 20 gal sump/regufium with macro algae and DSB. I'm curious to see how low it will go without a skimmer. Again, great job!
