Every tank has
a story.
A blank glass box. A vision. A spark of creativity.
What happens next is worth remembering.
TankJournal is a free aquarium journaling app. Hobbyists document tank builds with photos, track water parameters, livestock and equipment over time, and share journals with a community of aquarists.
More than a beautiful aquarium
A living, breathing story.
It's the thrill of sketching your first hardscape. The patience of watching a carpet plant take root, leaf by vibrant leaf. The triumph of finding the balance that lets your ecosystem thrive.
Those moments deserve more than a forgotten photo album or a fleeting place in a busy feed. TankJournal is a dedicated home for your aquarium's evolution, the details behind it, and the people who understand why it matters.
Rooted in the hobby.Built for the community.
Meet the founder
Born out of pure
hobbyist passion.
I'm Sonny aka PhoKing. My love for this hobby is anchored right here in the Southern California Aquatic Plants Enthusiasts Club — SCAPE.
SCAPE brings aquarists together around knowledge, scientific understanding, and an appreciation for the art of planted tanks. That same spirit of curiosity and generosity is at the heart of TankJournal.
Like so many of you, I can spend hours admiring stunning aquascapes, vibrant reefs, and tiny ecosystems. But a beautiful picture only tells half the story.
What light grew those plants?
What keeps that water so clear?
What's helping that livestock thrive?
That curiosity is how TankJournal was born.
