How we test and score
We evaluate planted tank equipment on the parameters that actually drive plant health and scape longevity, not marketing claims -- because a light with impressive PAR numbers at six inches can deliver less than 20 umol at the substrate of a twelve-inch-deep tank.
Who reviews these picks
Maya Thornton, Planted tank keeper since 2019
Maya has maintained freshwater planted aquariums since 2019, spanning low-tech Walstad tanks, high-tech Iwagumi CO2 setups, and dedicated caridina shrimp aquariums. She reviews equipment with an emphasis on real-world plant growth results and long-term reliability over manufacturer specifications.
What we score on
Every pick is judged on the same criteria. We weight them by what actually matters for the way you will use the gear, then write up the tradeoffs honestly.
PAR and spectrum honesty
We describe light output at substrate depth for the tank size the fixture targets, not peak output at the lens.
CO2 system reliability
Regulators are evaluated on pressure stability across the cylinder life and end-of-tank dump risk, not just initial output precision.
Substrate chemistry
Active soils are assessed for buffering consistency, ammonia release severity, and how they interact with shrimp and plant roots over an 18-month horizon.
Shrimp safety
Fertilizers, conditioners, and equipment are checked for copper content and invertebrate compatibility before any recommendation in a shrimp-kept tank.
Long-term value
Price weighed against reliability across a real maintenance cycle: filter media longevity, bulb replacement cost, regulator rebuild parts availability.
How our picks work
Each category roundup is ranked by our editorial score. The highest-scored option carries the Top Pick badge. Separately, the option that delivers the most for the money carries the Best Value badge. They are often different products on purpose: the best-scored is not always the smartest buy for most people, and we tell you which is which.
What we never do
- We take no payment, free product, or sponsorship in exchange for coverage or a ranking. There are no paid placements.
- We say what is wrong with a product, not just what is right. Every pick lists real tradeoffs.
- We match recommendations to your situation (fitment, skill level, budget, and use case) instead of pushing one product on everyone.
- We keep our picks current and re-check them as products and prices change.
