Where our facts come from

Equipment specifications come from the maker of each US model, and tank sizes from the tank makers. Fish and plant care ranges are standard hobby guidance; names, origins and adult sizes are checked against Wikipedia. Each sick-fish page lists its references: two chapters of the Merck Veterinary Manual and the University of Florida’s guide to ammonia. The references behind the care guides are listed below.

What a source means

Each source is the maker’s page, manual or published guidance behind the facts shown here. Specifications and dimensions do not change once a model exists, so they carry their source and no date. Model changes, which can move, show the date we last read them. A source is not a promise of current stock or a new test of the equipment.

When a maker doesn’t publish a specification, we say so rather than guess. Different generations and wattages of a model each get their own page. Pump output, filter circulation and maximum flow keep the maker’s own labels; none of them is the flow you’ll get once the filter is running in your tank.

If a detail is missing, the label and manual for your equipment are the best answer. Replaced and renamed models covers the differences that matter.

Calculations and units

The tools use your measurements and visible arithmetic. A US gallon is 231 cubic inches or 3.785411784 liters; a pound is 0.45359237 kilograms. NIST Guide to the SI, Appendix B: conversion factors.

Water weight uses approximately 1 kilogram per liter of freshwater. This is a planning approximation, not a density measurement. A weight total can’t tell you whether the glass, stand or floor will hold it.

Flow is collected volume divided by elapsed time. Turnover divides hourly flow by your actual water volume; it doesn’t pick a rate for your fish. Electricity is watts divided by 1,000, multiplied by operating hours and your tariff. Annual comparisons use a stated 365-day period. The numbers the tools open with are examples, not recommended water changes, schedules or prices.

Manufacturer and care references

Pictures and product choices

Product photos, when available, show the exact Amazon item and link to it. They come through Amazon’s licensed image service and expire within 23 hours. A missing photo does not change the equipment choice. Diagrams of tank measurements and calculation steps are our own explanatory drawings.

Fish and plant photos are real photographs from Wikimedia Commons, listed below with their authors and licenses. The tanks, lineups and scenes drawn to scale are our own drawings.

We compare published specifications and instructions. We do not claim hands-on equipment testing. Retailer commissions do not set product order. See the affiliate disclosure for that relationship.

We resize and crop them to fit and credit them on every page that shows them. Where a photo shows a close relative or a color form, the note says so.
