My tank is 14+ months old and have clown, tang, butterfly, watchman fish and a cleaner shrimp. It is 55G tank.
My nitrate level consistenly remains at 20. All others including amonia remains at 0. I tested the water that I use and it also shows 0 for nitrate. I have 2 stage water treatment system installed thus don't use RO/DI water from shops.
Is it ok to leave nitrate at 20?. If not, how do I reduce that?.
