I'm a bit confused with an ammonia spike. The tank is cycling, and it is day 18 today. The ammonia spiked up to about 0.4, which I expected with the Fluval statrum substrate. On day 15 the levels where a trace to 0.1. Today I did a 50% water change and thought I would check, expecting it to be 0 to maybe a trace, and it is 0.6. I plan to do another water change again tomorrow, but I can't understand why it's gone up so far? Would appreciate any help with the reason why.
