Why Trust TanninLab

Independent research. Plain answers. No inventory to move.

Our Position

We are not a shop. We do not sell fish, plants, or gear. We research products from manufacturer specifications, labels and published husbandry sources, and we name where each number comes from. We do not run lab or in-tank tests. Brands do not pay for placement and never see our content before publication.

How We Research

Every recommendation is built from manufacturer specifications, product labels, published husbandry sources and owner reports. We set the stated figures side by side and say which source each one comes from. When a claim is only a marketing line, the guide says so.

Independence Guarantee

Affiliate commissions, including Amazon Associates earnings, fund the site and do not change what we recommend. We do not take payment for placement and we do not publish sponsored posts. If the specs or owner reports show a product is a poor fit, we say so, even when it pays a commission.

The Blackwater Perspective

TanninLab has a signature point of view: botanicals and natural blackwater methods can suit many soft-water species, including bettas and shrimp. We base that on published husbandry sources and keeper reports, not ideology. When the evidence contradicts a blackwater practice, we follow the evidence.

Not Veterinary Advice

Our fish and shrimp health guides are general information. If an animal is sick, gasping or losing color fast, ask an aquatic veterinarian or a qualified fish-health specialist instead of relying on a guide alone.

Updates and Corrections

Each guide shows when it was last updated, and we revise guides when specs, labels or sources change. If you find an error, email [email protected] with the link and the fix, and we will check it.
