The first 30 days of a freshwater tank
What actually happens in the water column from setup day to first stable readings — and how to stop the standard new-tank mistakes from killing fish.
The first month of a new freshwater tank is when most of the well-intentioned mistakes happen. Ammonia spikes, premature stocking, water changes that reset the cycle, daily testing that catches drift no one knows how to read yet.
This guide walks the first thirty days as a calendar — what to test, what to do, what to ignore, and how to know the cycle is actually finished. Manfred walks slow, because new tanks reward slow.
Full prose coming soon. The framework, schemas, and dosing calculator referenced here are already live.
