## Aquarium Size Description
Aquarium Planner & Water Math is a practical aquarium calculator built for freshwater and saltwater keepers who want clean numbers before making changes. Instead of juggling notes, forums, and multiple conversion apps, you can calculate core tank values in one place and move from idea to action with less guesswork.

Whether you are setting up a first tank, resizing a system, balancing routine maintenance, or managing multiple aquariums, this app helps you run the day-to-day math that matters: volume, water weight, water changes, dosing amounts, stocking load, and unit conversion.

Core Aquarium Calculators
- Aquarium size calculator for rectangular, hexagon, cylinder, half-cylinder, and quarter-cylinder tanks.
- Surface area calculator to estimate top area quickly for planning and comparison.
- Aquarium volume calculator with conversions to US gallons, Imperial gallons, liters, cubic inches, and cubic centimeters.
- Water weight calculator in pounds and kilograms with salinity factor support.
- Setup planner that estimates substrate amount and water weight from tank volume.
- Water change calculator that estimates required change percent and approximate gallons to replace.
- Chemical dosing calculator for dechlorinator, fertilizer, salt, and medication workflows.
- Stocking helper that estimates fish-per-gallon ratio and flags light, moderate, heavy, or overstocked bioload ranges.

Built for Real Aquarium Workflows
- Fast forms with direct inputs and clear output labels.
- Designed for practical use during maintenance, setup, and upgrade planning.
- Saved values in key tools so common numbers are easier to reuse.
- Share-ready summaries for logging, team communication, or shop consultation.
- Simple results you can read quickly while standing at the tank.

Included Unit Converters
- Pressure converter: psi, kPa, bar, and atm.
- Temperature converter: Celsius, Fahrenheit, and Kelvin.
- Volume converter: US gal, Imperial gal, liters, in3, and cm3.
- Flow rate converter: US gph, US gpm, L/h, and L/min.

Why Keepers Use It Daily
- Check tank size and water volume before buying equipment.
- Estimate water changes before nitrate correction days.
- Verify dosing totals before adding any treatment.
- Compare stocking plans with a quick bioload estimate.
- Convert pump flow and volume units without opening another app.
- Keep maintenance decisions consistent across tanks.

Useful for Many Types of Keepers
- Beginner aquarium owners learning core maintenance math.
- Intermediate hobbyists tuning routine care and dosing.
- Advanced aquarists managing larger systems and custom geometries.
- Store staff and maintenance providers who need quick, repeatable calculations.

Aquarium Planner & Water Math does not replace species research, quarantine protocol, or veterinary guidance. It gives you a dependable numerical baseline so your husbandry decisions start from solid measurements, not rough estimates.

If you want an aquarium app that focuses on useful calculations, clear outputs, and repeatable maintenance planning, this is a reliable daily tool for freshwater and marine setups.

Typical Weekly Uses
- Pre-mix planning for routine water changes.
- Quick confirmation before dosing supplements or treatments.
- Pump flow conversion when evaluating filter upgrades.
- Stocking ratio checks before adding new fish.
- Setup math for new tanks, quarantine tanks, and temporary grow-out systems.
