Safe to add ferts in the discus planted tank
I have a planted low light discus tank.
Now,,i have java fern,java moss,anibus in the tank and im thinking of doseing some ferts.
Im keeping nitrates low as possible with water changes.so dont need any no3...and my phosphate level is 0.5 so thats ok....what im wondering is,is it ok and safe to add some flourish traces?
Also would dosein potassium be safe?
im usein pure ro water buffered and ro righted
