its not a bad kit at all above.
the real fun is when the tester shows about 4 ppm lol and the tank posting is exactly like yours, fine, nothing wrong, nothing going wrong in the future....when these kits get adulterated the discussions can pan out pages but in the end its all the same (many posters have already added Prime for the first .25 scare, dont disclose it in the description, now its darker reading than yours, but prime is one api adulterant for both ammonia and nitrite false reads/example)
no cycle stalls, no cycle fails to complete, no cycle starves out or gets weak over time. that rule makes ammonia tracing very easy.
case in point, my bacteria have been dead for 90 days but all my life looks great and eats great day to day. *if copper really was a factor the tank would simply crash unable to control ammonia, ammonia never hovers at a set level in a reef tank. when it does, the tester is faulty.
So, as of today, I've: Turned off the skimmer completely for a week (didn't realize that was a thing with bacteria additives) Filtered with carbon for a week ahead of time (turned off now) Pumped 15 gallons (20%) out of the tank Carefully sifted about 15 dead snails out of the sand bed Added 15...
