Freshwater planted-tank hardware
Lights, substrate, CO2, filters, and heaters — researched, not invented.
Planted Tank Reviews is a research-based guide to the hardware that actually runs a planted aquarium. We compare named SKUs, publish affiliate links with a disclosed Associates tag, and stay off livestock, disease, and medication topics.
Eight hardware pillars
These first guides cover the highest-intent planted-tank hardware queries we mapped from live US search data on 2026-08-24. Each article is a full buying guide, not a thin listicle. This is a research-based site, not a hands-on test lab.

Lights, substrate, pressurized CO2 kits, hang-on-back and canister filters, and heaters. We do not sell or review livestock, live plants as products, or medications.
Named SKUs
When we recommend a light or filter, we name the current model and, when we can verify it, a real Amazon product ID. We do not invent ASINs.
