The Nitrogen Cycle Handbook
$99.00
A new tank kills fish for a reason that is invisible in the water and obvious in a test tube. Ammonia builds with nothing to convert it, and the tank looks perfect the entire time.
This handbook explains what is happening, gives you two methods depending on whether fish are already in the tank, and tells you exactly when the process is finished.
What is inside
- The chemistry in plain language: ammonia, nitrite, nitrate and the two bacteria
- Fishless cycling in nine steps, with a day-by-day expectation table
- Fish-in cycling as a rescue protocol, including the 0.25 ppm water change rule
- Six stall scenarios and how to restart a cycle that has gone quiet
- How to keep the colony alive through medication, filter cleaning and power cuts
- The shortcut that genuinely works, and the one that mostly does not
- A printable cycling log
Who it is for
Anyone setting up a first freshwater tank, and anyone whose fish keep dying in the first two months for no visible reason.
