Built around the jobs fishkeepers actually do
Check every reading against the right range
Log ammonia, nitrite, nitrate, pH, GH, KH and temperature, plus salinity, calcium, alkalinity and magnesium for reef. Each reading is checked against the band for that tank type.
Test resultsIn or out of rangeKnow when a new tank has cycled
Log ammonia, nitrite and nitrate each day. The tracker reads the curve and shows which stage the tank is in, all the way to Cycled.
Daily NH3, NO2, NO3Cycle stageKeep water changes on schedule
Record water changes, filter cleans, media swaps and dosing. Days since and next due fill in, and the Dashboard counts tanks that are overdue.
Water changes, cleansNext dueKeep a record of every fish, coral and invert
Cost, source and date added for each one, and the date and likely cause if one is lost. The Dashboard shows total spend and your survival rate.
Livestock, costSurvival rateCheck stocking before you buy
Enter the adult size of each species and the Tanks tab estimates the load against tank volume, from Empty to Overstocked.
Adult sizesStocking levelService gear before it fails
Filters, heaters, lights and pumps with service intervals and lifespan, so a bulb or heater that is due shows up on its own.

Before you buy
I keep freshwater, not reef. Is it still a fit?
Yes. Choose Freshwater, Planted, Cichlid, Brackish or Shrimp and your readings are checked against that range. The reef-only columns simply stay empty.
Can I track more than one tank?
Yes. Every log has a Tank column and the Dashboard lines up all your tanks side by side, from a single betta tank to a full fish room.
Can I change the target ranges?
Yes. The low and high values for all six tank types are editable on Settings, along with water change and test intervals and the stocking rule.
How many entries does it hold?
Each log has 500 rows, covering water tests, cycling entries, maintenance, livestock, plants and equipment.
What do I get?
An Excel file (.xlsx), a filled-in sample to look at, and a quick-start PDF guide with a link that makes your own copy in Google Sheets.
How does delivery work?
You get your download links right after checkout, and Stripe emails your receipt. There is nothing to ship and nothing to wait for.
How do I set it up in Google Sheets?
Open the quick-start PDF and click the Google Sheets link. Google makes a copy in your own Drive that only you can edit. You need a free Google account.
Will it work on a Mac?
Yes. It works in Excel on Mac and Windows, and in Google Sheets in any browser.
I'm not a spreadsheet person. Is that a problem?
No. You only type in the yellow cells. Everything in gray works itself out, and the Start Here tab shows you where to begin.
Can I get a refund?
