Have a new set I started Monday. It’s a 54 gallon corner that I am using as a planted scape and fish-less as of now. Wanting a good few cycles before I start introducing fish. My test today indicated that my ammonia is at .25ppm, nitrite is 0 and nitrates were at almost 20ppm, according to API’s master test kit. I am curious as to what I should be expecting as I progress and what % water recommendation would be best moving forward. I took water from an already established tank (roughly 10 gallons), sponge filter from that tank, and Carib-sea eco complete substrate with some Monte Carlo, penny wort and water sprite to start. Any help or advise would be greatly appreciated.
