Hey guys ,
I have a 60 l planted running for 2 months now . On the back I use substract pro some eheim sponges and some filter wool.
The problem is that I have a bit high nitrate arround 50ppm, while I do 50% weekly water change,feed sparingly and have a few plants in .....
Each time I take filter wool out is brown and I believe there are decaying materials in there that raise the nitrate. Should I completely remove it from my aquarium ?
