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.
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.
Nitrate · last nine 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.
Never miss a water change.
Set a cadence once: weekly change, filter rinse, dosing, RO top-off. Anything overdue rises to the top until it's checked off.
Watch it grow in.
Thirty shots per tank. Look back on a bare setup filling into a mature scape, one month at a time.
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.

Planner
Sketch equipment, stocking, and budget for the next build, then convert it to a real tank
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.
Whatever water you keep.
Guides grouped the way aquarists actually stock: by water, by family, by difficulty. Every profile carries the ranges TankBud checks your tank against.
Too many fish, or room to add?
Set a tank size, add the species you are considering, and get a straight answer on stocking plus temperature and pH fit. It runs on the same curated ranges as the care guides, free and without an account, and the plan saves to the planner when you are ready.

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.
Send the tank,
not screenshots.
Turn on sharing and any tank or plan gets a view-only page at its own link. Post it in the club thread, or send it to the friend who wants the full stock list.

- Client tanks, notes and photos in one workspace
- Service visits logged like any other entry
- Plans that turn into invoices
