One doesn't mean the other...... Cycled tanks can lose their bio-capacity for a variety of reasons. The net result is the same. Just consider it a "mini-cycle!" ; )
Dark yellow ? Use sunlight or a halogen ... The nitrate test can be hard to read (for me atleast) How dark are we talking and are you holding the tube directly to the card just to the right of the colors ?paulz01;2709329; said:Alright guys good news i bought a new test kit. it's the API liquid test comes with 2 bottles of chemicals to test the water.
Anyways the card says 0ppm ammonia is Light yellow. but my reading seem to be Dark yellow. Is this normal? Tested in 3 times now. 8 drops from each bottle in the 5 ml tube.
