Here's another update on the tank. It's now day 14 of the cycle and everything is going great and at a fast pace. Here are my parameters so far ammonia is 0ppm after peaking at ~1, nitrite is at ~2ppm after going off the chart, and nitrates are ~40ppm. No algae blooms have happened, only change is powerheads and rock have what I would call a layer of biofilm on them since it's a milky tan color. The only questions I have is when nitrite goes to 0 is the tank considered cycled like freshwater or will nitrates also start to drop, do I need to do a Water change once done, and if so how big? Thank in advance for the help.
