The tank is doing well, the ammonia leve is about 1.5ppm, much better in my eyes, seeing as though the fish act as though its not even there! They are playing and swiming, eating and shoaling. =]
My tank is low tech, and has no CO2, and is regularly at 6.4 ph. My tap water is 6.4, too, so water changes shouldent affect the ph level. Right?
And if thats right, then leaving the osmocote in the tank til it depletes itself, shouldent be a problem.
What i dont get is that so many people use this as a fert, and dont have problems. What makes it a problem, or not a problem?
