Fishless Aquarium Cycling Planner: Ammonia Dose Math for Your Tank Volume, Daily Test Log, Nitrite Stall and pH Crash Fixes, the 24 Hour Completion Test, and a Safe First Stocking Day

Cycle a new freshwater tank without fish: work out a starting ammonia dose for your actual water volume, follow a test schedule for ammonia, nitrite, nitrate, and pH, fix a nitrite stall or a pH crash, confirm the cycle with the 24 hour test, and plan the water change and first fish so nothing dies in week one.

Act as an aquarium store manager who has talked hundreds of new fishkeepers through fishless cycling and who knows the usual week three problems: nitrite stuck off the chart, pH falling, and the urge to add fish too early. Inputs: - Tank size, actual water volume after substrate and decor, filter type, heater setting: [TankSetup] - Ammonia source and its strength from the label (pure ammonia solution, ammonium chloride drops, fish food): [AmmoniaSource] - Test kit used and whether it reads total ammonia: [TestKit] - Tap water results: pH, KH, GH, and ammonia straight from the tap, plus the water conditioner used: [TapWater] - Your test log so far, by day: [TestLog] - Fish you plan to keep first: [StockingPlan] - Output format: [Format] Generate: 1. A dose calculation for AmmoniaSource and the real volume in TankSetup to reach about 2 ppm total ammonia, shown as math, with the instruction to add half, test after 30 minutes, then top up, because label strengths vary. 2. A test schedule: what to test each day or every other day in each phase (ammonia dropping, nitrite rising, nitrate appearing), when to redose back to 2 ppm, and what each phase usually looks like in the log. 3. A reading of TestLog: which phase the tank is in and what to do today. 4. Stall fixes: nitrite above what the kit can read (partial water change to bring it down, stop dosing until it falls), pH under about 6.5 or KH near zero (water change or a small baking soda dose to raise KH), and low temperature slowing bacteria. 5. The completion test: dose to 2 ppm and confirm 0 ammonia and 0 nitrite 24 hours later, on two or three days in a row. 6. A first stocking day plan for StockingPlan: a large water change to bring nitrate down, keep dosing until fish arrive, add fish within a day or two, stock gradually, and feed lightly the first week. 7. A note on bottled bacteria: it can shorten the cycle, but the completion test still decides. Constraints: - Use only ammonia without surfactants or fragrance; tell the user to shake the bottle and check for foam. - Do not promise a number of days; cycles vary. - For saltwater tanks or sick fish, say this plan is for freshwater fishless cycling only. No em dashes.
