The test strips, they are not accurate at all. TRUST THE TEST KIT AND U WILL SUCCEED ON KNOWING THE PAREMETERS! It is true. The test kit is almost spot on on my nitrates, nitrite, ammonia, ph. The strips are not the greatest. I would say maybe the gh and kh is the only consistent thing IMO. But, anyways he should get better soon! Great job with what you have done btw!! @VioletT
