About AquariumLab
AquariumLab is a science-based fishkeeping resource covering freshwater, saltwater, and planted tank setups. We write practical care guides backed by aquarium science — with honest equipment recommendations and no sponsored fluff.
Our Mission
Too much fishkeeping advice online is based on outdated "rules of thumb" that don't hold up to scrutiny — things like the inch-per-gallon stocking rule or the claim that you need expensive equipment to get started. AquariumLab publishes practical, research-backed guides that help aquarists at every level make better decisions: what fish to start with, how to cycle a tank properly, which filter actually works for their setup, and how to read a water test correctly. Honest equipment recommendations. Real care requirements. No hype.
What We Cover
- Fish Care Guides — Detailed species profiles for freshwater and saltwater fish, including tank size, water parameters, diet, and compatibility.
- Tank Setup & Equipment — Reviews of filters, heaters, lighting, and complete beginner tank setups — with real-world comparisons and honest picks.
- Water Chemistry — The nitrogen cycle, pH, hardness, ammonia, nitrite, nitrate — explained clearly so you can keep water parameters stable.
- Planted Tanks — Beginner-friendly plant guides, CO2 systems, substrate options, and lighting recommendations for live planted setups.
