A calm home for every tank you keep

Keep a proper record.
Keep a healthier tank.

Water tests, dosing, water changes, livestock, plants: every tank you keep, on one record you'll actually keep up with. No spreadsheet gymnastics, no guessing where the cycle's at.

On the record

One tank.
Everything about it,
in one place.

No feature soup, just the eight things a tank actually needs kept track of, each on its own page and linked to the rest.

Water testspH, ammonia, nitrite, nitrate, GH/KH. Trended, not guessed

RemindersRecurring water changes, dosing, filter media; overdue floats up

LivestockFish, shrimp, snails: counts, sources, and whether your water suits them

PlantsSpecies, placement, light and CO₂ notes for the whole scape

Equipment & materialsFilters, lights, heaters, substrate: what's running and what's on hand

LogsTrims, observations, dosing changes: the running story of the tank

PhotosA visual history of how the scape grew in, month over month

PlannerSketch equipment, stocking, and budget for the next build, then convert it to a real tank

How it works, day to day

Simple to start.
As detailed as you care to get.

Start with a name and a volume. Layer in tests, livestock, and routines as the tank, and your own eye for it, grow.

Water tests

Read the trend,
not the moment.

One reading is a snapshot. Nine of them tell you the tank is drifting before the fish do. Every parameter is plotted against the range your profile expects: freshwater, planted, or cycling.

Reminders

Never miss
a water change.

Set a cadence once: weekly change, filter rinse, dosing, RO top-off. Anything overdue rises to the top of every view until it's checked off.

Photos

Watch it grow in.

Thirty shots per tank. Look back on a bare setup filling into a mature scape, one month at a time. It's the part of the hobby that's easiest to forget you earned.

Stocking & water fit

Will your water
actually suit them?

Every inhabitant is checked against the catalog's temperature, pH, and tank-size ranges, then against your latest test. TankBud tells you who's thriving, who to watch, and exactly which number is off.

Care guides

Whatever water you keep.

Planner

Plan the build.
Track the budget.

Draft a tank before a drop of water goes in: equipment, livestock, plants, hardscape. Watch the cost and the stocking add up, tick things off as they arrive, then convert the whole plan into a real tank.
