Reef Aquarium
Reef aquariums are the pinnacle of the marine hobby — living coral ecosystems filled with colour, movement, biodiversity, and natural beauty. A reef tank is more than an aquarium; it’s a miniature ocean where corals grow, fish interact, invertebrates clean and forage, and rockwork becomes alive with microfauna.
This is a complete reef‑keeping resource: setup guides, coral care, equipment breakdowns, water chemistry, stocking advice, troubleshooting, and species profiles. Whether you’re building your first nano reef or designing a high‑end SPS system, this is your starting point.
What Makes Reef Aquariums Unique?
Reef tanks combine:
Living corals
Marine fish
Invertebrates
Live rock
Microfauna
Complex water chemistry
High‑end equipment
Dynamic flow and lighting
They are more demanding than fish‑only saltwater tanks, but also more stable and rewarding once properly set up.
Reef aquariums offer:
Vibrant coral colours
Natural reef behaviour
Endless aquascaping creativity
Long‑term coral growth and propagation
A thriving ecosystem that evolves over time
Start Here: The Reef Fundamentals
✔ Reef Aquarium Setup Guide
Tank size, aquascaping, live rock, sand, cycling, equipment, stocking.
✔ Beginner’s Guide to Reef Aquariums
A complete beginner pathway covering coral selection, fish compatibility, maintenance, and common mistakes.
✔ Reef Cycling Guide (Marine Nitrogen Cycle)
How to cycle a reef tank using live rock, bottled bacteria, and proper testing.
✔ Reef Water Chemistry Guide
Alkalinity, calcium, magnesium, pH, salinity, nitrate, phosphate — and how to keep them stable.
✔ Reef Maintenance Guide
Weekly, monthly, and seasonal routines for coral‑safe cleaning and long‑term stability.
Reef Tank Types
Reef aquariums come in three main styles, each with unique care requirements.
Soft Coral Reefs (Beginner‑Friendly)
Low demand, forgiving, great movement.
LPS Coral Reefs (Intermediate)
Large polyp corals, moderate lighting and flow.
SPS Coral Reefs (Advanced)
High‑demand corals requiring strong lighting, stable chemistry, and high flow.
Each reef type has its own extended guide within your reef section.
Explore Coral Groups
Corals are living animals with unique care needs.
Soft Corals
Zoanthids
Mushrooms
Leathers
LPS Corals
Hammer
Torch
Frogspawn
Acan
Candy Cane
SPS Corals
Acropora
Montipora
Birdsnest
Each coral group has its own extended care guide and placement charts.
Reef Fish & Invertebrates
Reef‑safe fish and invertebrates bring movement, colour, and biodiversity.
Reef‑Safe Fish
Clownfish
Gobies
Blennies
Wrasses (reef‑safe species)
Chromis
Reef Invertebrates
Cleaner shrimp
Hermit crabs
Snails
Feather dusters
Sea stars
Your reef section includes compatibility charts, stocking guides, and behaviour notes.
Reef Equipment & Technology
Reef tanks rely on specialised equipment to maintain coral health and water stability.
✔ Protein Skimmers
Remove dissolved organics and improve water clarity.
✔ Wavemakers & Flow Pumps
Essential for coral health, gas exchange, and nutrient transport.
✔ Reef Lighting
PAR, spectrum, photoperiod, and coral‑specific lighting requirements.
✔ RO/DI Systems
Purify water for mixing salt and topping off evaporation.
✔ Auto Top‑Off (ATO) Systems
Maintain stable salinity — critical for reef tanks.
✔ Dosing Pumps
Automate alkalinity, calcium, and magnesium dosing.
✔ Reef Test Kits & Controllers
Monitor alkalinity, calcium, magnesium, nitrate, phosphate, pH, and temperature.
Each equipment category has its own long‑form guide.
Reef Water Chemistry
Reef chemistry is more complex than freshwater or fish‑only saltwater, but also more predictable once mastered.
Key Parameters
Alkalinity (dKH)
Calcium (Ca)
Magnesium (Mg)
Nitrate
Phosphate
Salinity
pH
Temperature
Your chemistry section explains each parameter, how to test it, how to adjust it, and how to maintain stability.
Troubleshooting & Problem‑Solving
Reef tanks can experience unique issues. Your reef section includes complete guides for:
Coral bleaching
Coral recession
Algae control (cyano, dinos, GHA, bubble algae)
Nutrient imbalance
Flow problems
Lighting issues
Salinity swings
Fish disease (marine ich, velvet, brooklynella)
Coral pests (flatworms, nudibranchs, aiptasia)
These guides help readers diagnose issues early and take safe, effective action.
