What's New in AquaticLog

26.1.1

July 17, 2026

A big one. AquaticLog has a brand-new look. - A refreshed design throughout, with a deeper, calmer reef-navy theme that puts your tanks, parameters and photos front and center. - Redesigned aquarium switcher with photo tiles, so jumping between tanks is faster and more visual. - Swipe left or right on the aquarium view to move between your tanks even faster. - Now in ten languages, adding Russian and Ukrainian: English, German, Spanish, French, Italian, Dutch, Polish, Russian, Ukrainian and Brazilian Portuguese. - Drag to reorder your aquariums — the home tank switcher follows your order. - Manage your aquariums straight from the tank switcher: rename, reorder, retire or delete a tank, and bring retired tanks back — no digging into Settings. - Add how long each reminder takes and see your total maintenance time per day and per week at a glance. - Track EC as a water parameter, with uS and mS units. - Polished screens across parameters, reminders, inhabitants, photos and more. - Log routine care in one tap: recent products appear on the Dosing and Feeding cards, and your last water change is one tap to repeat — all prefilled with your last amounts. - Copy a snapshot of your tank — parameters, livestock, equipment and schedule — with one tap, ready to paste into forums or messages when you ask for advice. - Adding a dose or feeding suggests products you have logged before, so there is no retyping names and amounts. - Add notes while entering water test results, without returning to parameter history afterward. - Fix ICP results by hand: tap any value in an ICP test to correct a misread number or remove it. - Redesigned species browser: a photo card grid, a quick strip of family and genus groups, and a filter sheet for water type, lifeform, care level, temperament and reef-safe — matching varieties surface right in search. - Redesigned products browser to match: a photo card grid sorted by popularity, category tiles with counts, and category and brand filters over the full catalog. - New product pages show ratings, how many tanks run each product, and dosing guidance — add a product to your tank or shopping list right from its page. - Much faster startup and reminder syncing for accounts with many aquariums. - New to AquaticLog? Log water parameters without limits during your first 30 days. - Try Pro free for 7 days with the yearly plan. - The Pro screen now shows your real yearly savings at a glance. - Performance improvements and bug fixes throughout. Thank you for keeping your tanks with AquaticLog. Your reviews and feedback shape every update, so keep them coming.

10 measurements per month

Limiting you to 10 measurements per month is ridiculous.

Awesome app

Great way to log your water test parameters

What a joke

After 2+ years of using Aquatic Log, now you have to pay for premium to log more than 10 things.

Organized and great features

Great app for chronicling an aquarium. I use it for both a FW and a reef tank. I like seeing the graphs of my parameters and being able to upload ICP tests. I tried a couple other apps but like this one the best by far. I do appreciate not being forced to see ads or urged to buy things. Such a relief. Get this one!

Unhappy

All of a sudden I have lost all my entries of inhabitants. Wasted 3 years of records to be told you have to pay me to keep seeing them.
