The First 30 Days Checklist

Most new-tank trouble is an order problem, not a knowledge problem: fish go in before the tank is cycled, and the water starts swinging. This two-page printable is the order that keeps a tank stable — set it up and let it cycle, first fish only after ammonia and nitrite both read zero, then one small weekly routine.

  • Week 1 — set the tank up and let it cycle, with a daily test log
  • Weeks 2–3 — how to read the peak, and when the tank is cycled
  • Week 4 — first fish, in the right numbers, fed the right amount
  • From day 30 — the 25-minute routine that keeps it stable

Free, one email. We send the checklist link and nothing else unless you buy from us.

The checklist is the skeleton. The Full Tank Mastery Bundle is the whole system: three progressive guides, a tank planner, a water log that explains every number, an algae finder with a picture key, and maintenance schedules — $29 once, with a 30-day refund.
