Aquarium Guides
Short, practical guides written around our calculators — no fluff, no myths, just the numbers and why they matter.

In progress
We are building a full suite of aquarium tools. Each will follow the same principles as the volume calculator: transparent formulas, sensible defaults and mobile-first design.
- Aquarium heater calculator — wattage from volume and room temperature
- Filter flow calculator — turnover per hour for your tank size
- Water change calculator — how much water to replace and dose
- Aquarium weight calculator — floor load from water, glass and stand
- Aquarium stocking calculator — community compatibility by volume
- CO₂ and lighting calculators — planted tank dosing and photoperiod
