I tested my water this morning (using API master test kit) and when I put the drops in the tube to test the ammonia, it didn't turn color at all...what does this mean?
make sure you follow instructions as said if you dont use both bottles the water will not change in some cases .instructions on the back of the cards you get with the test kit i have the same one.
Yea! I was nervous because like a retard I put in a new filter and changed the substrate and most of the water within 2 days! But I can't tell what my ph is?
